Description

  The present invention relates to a control device and a control program, and more particularly to a control device and a control program used mainly for dam control.

  For dams, when water is used to supply water downstream or when it is discharged by flood control during flooding, the conditions for the amount of water flowing into the reservoir of the dam and the amount of water discharged from the dam at present For example, the discharge flow rate (ideal discharge flow rate) discharged downstream is calculated. After calculating the ideal discharge flow rate, the target opening degree of the gate (sluice gate) provided in the discharge facility is calculated so that the ideal discharge flow rate is obtained. Since it is difficult to finely adjust the gate to be equal to the ideal discharge flow rate, the target opening is calculated so that the flow rate is as close as possible to the ideal discharge flow rate and does not exceed the ideal discharge flow rate.

Control after calculation of the target opening may be automatic control by the control device when the flow rate is relatively small, for example, downstream discharge for water use purposes, but in discharge with a large flow rate such as during floods. The operator has given permission to change the opening of the gate based on the calculated target opening, monitoring after changing the opening, and giving a stop instruction in case of abnormal discharge (for example, see Patent Document 1).
JP 2000-38715 A

  However, an opening change permission may be given to a gate that should not be opened due to an error in the control program. In such a case, an abnormality will be noticed only after the discharge occurs. Whether or not an abnormality is noticed depends largely on the skill of the operator. If the experience is inexperienced, the abnormality cannot be detected immediately, and overdischarge exceeding the ideal discharge flow may occur.

  The present invention has been made in view of such a point, and an object thereof is to provide a control device and a control program capable of easily and surely preventing erroneous discharge.

  The control monitoring unit 6 acquires the calculation result output from the control calculation unit 2 and determines whether the calculation result is correct. If the calculation result is incorrect, the control monitoring unit 6 releases a signal for stopping the adjustment of the discharge flow rate based on the calculation result. Transmit to device 5.

  According to such a control device 1, the control operation unit 2 performs an operation for determining the discharge amount of the dam 3. The calculation result is transmitted to the discharge device 5 by the transmission unit 4. When the calculation result output from the control calculation unit 2 is acquired by the control monitoring unit 6, the correctness of the calculation result is determined. If the calculation result is incorrect, the signal for stopping the adjustment of the discharge flow rate based on the calculation result Is transmitted to the discharge device 5.

  In order to solve the above problem, in a control program mainly used for dam control, the computer calculates control flow for calculating the discharge flow rate of the dam, and the discharge flow rate based on the calculation result of the control calculation unit. To the discharge device for adjusting the calculation result, transmitting means for transmitting the calculation result, obtaining the calculation result output from the control calculation means to determine the correctness of the calculation result, if the calculation result is incorrect, There is provided a control program that functions as control monitoring means for transmitting a signal for stopping the adjustment of the discharge flow rate based on the calculation result to the discharge device.

  If such a control program is executed by a computer, processing similar to that of the control device is executed.

A keyboard 52 and a mouse 53 are connected to the input interface 105. The input interface 105 transmits a signal sent from the keyboard 52 or the mouse 53 to the CPU 101 via the bus 107.

  The communication interface 106 is connected to the network 10. The communication interface 106 transmits / receives data to / from another computer via the network 10.

  With the hardware configuration as described above, the processing functions of the present embodiment can be realized. In order to perform control in a system having such a hardware configuration, the following functions are provided in the control device 100.

FIG. 4 is a block diagram illustrating functions of the control device.
The control device 100 includes a data storage unit 110, an arithmetic processing unit 120, a control arithmetic unit 130, a control monitoring unit 140, and an input / output processing unit 150.

  The data accumulating unit 110 accumulates (stores) a computation constant 20 necessary for computation processing, a control computation constant 21 necessary for control computation, a reservoir level-opening-discharge flow rate table 30, and a downstream discharge restriction table 40. )is doing. The control calculation constant 21 is a value input by, for example, an operator or the like operating the keyboard 52 or the like.

In the water storage level-opening-discharge flow rate table 30, the relationship among the water storage level, the gate opening, and the discharge flow rate is set.
The downstream discharge limit table 40 is provided to limit the downstream discharge flow rate so as not to cause a sudden change in the river level. The current discharge flow rate and the downstream discharge flow rate corresponding to the current discharge flow rate are provided. And the relationship is set. Although not shown in the drawing, the data storage unit 110 may be provided with a plurality of (other) tables that define the discharge amount to the downstream according to the purpose in order to prepare for an emergency such as a flood. .

The arithmetic processing unit 120 calculates the current discharge flow rate and displays the calculation result on the monitor 51, for example.
The control calculation unit 130 calculates the ideal target discharge flow rate based on the control calculation constant 21, the water level measured by the water level gauge 11, the current gate opening obtained from each discharge device 12, and the downstream discharge restriction table 40. calculate. Then, the control calculation unit 130 calculates each target opening degree of each gate 122 of each discharge device 12 to be controlled (changes the gate opening / closing amount) from the ideal target discharge flow rate. Then, each calculated target opening is transmitted to each discharge device 12 to be controlled via the input / output processing unit 150.

  The control monitoring unit 140 monitors each target opening output from the control calculation unit 130, and when determining that it is abnormal, transmits a stop instruction to each discharge device 12 to be controlled via the input / output processing unit 150. .

The input / output processing unit 150 constitutes an interface between each discharge device 12, the control calculation unit 130, and the control monitoring unit 140.
According to such a control device 100, when an operator or the like inputs a control calculation constant or the like necessary for control calculation using the keyboard 52 or the like, the control calculation constant is stored in the data storage unit 110. Then, when the operator inputs a value (for example, 10 t / sec) for setting the discharge amount of the dam using the keyboard 52 or the like, the control operation unit 130 inputs this value and the water level gauge 11 and each discharge device 12. Based on each current gate opening, the control calculation constant 21 and the lower limit discharge limit table 40, the ideal target discharge flow is calculated. Thereafter, the target opening for each gate 122 is calculated from the ideal target discharge flow, and a transmission confirmation screen for each target opening to each discharge device 12 is displayed on the monitor 51. When the operator permits transmission using the keyboard 52 or the like, the control calculation unit 130 outputs each target opening corresponding to each discharge device 12 to be controlled via the input / output processing unit 150. Thereafter, each target opening output by the control calculation unit 130 is monitored by the control monitoring unit 140, and when it is determined that these target openings are abnormal, the control object is controlled via the input / output processing unit 150. A stop instruction is transmitted to each discharge device 12. Thereby, each discharge device 12 to be controlled stops changing the gate opening degree by the target opening degree.

Next, the calculation operation (process) in which the control calculation unit 130 calculates the target opening degree will be described.
FIG. 5 is a flowchart showing a calculation operation for calculating the target opening.
First, the current discharge flow rate GQot of all the discharge devices 12, that is, the current discharge flow rate GQot for each gate 122 (one gate) is calculated (step S1). Specifically, the current discharge flow rate GQot for each gate 122 is calculated from the water storage level obtained from the water level gauge 11 and the current gate opening of each discharge device 12.

Next, the current discharge flow rate Qot is calculated by adding all the discharge flow rates GQot for each gate 122 calculated in step S1 (step S2).
Next, an ideal target discharge flow MQob for increasing or decreasing the current discharge flow rate Qot is calculated according to the discharge purpose (maintenance of the storage level, lowering of the water level, maintenance of the discharge flow rate, etc.) (step S3).

  Next, in order to secure the ideal target discharge flow rate MQob, the target opening degree G of each gate 122 in each discharge device 12 to be controlled for increasing or decreasing the discharge flow rate is calculated (step S4). Which gate 122 is to be opened and closed is determined by a predetermined priority order.

The calculation operation is thus completed.
Next, the operation of each step of the calculation operation will be described in more detail.
<1> Calculation of Current Discharge Flow Rate GQot in Step S1 In the present embodiment, calculation is performed by an interpolation approximation method using the stored water level-opening-discharge flow rate table 30.

FIG. 6 is a diagram (table) showing a water storage level-opening-discharge flow rate table.
In the water storage level-opening-discharge flow rate table 30 shown in FIG. 6, the opening G _(k) (k = 1 to X) indicates the gate opening (unit: (cm / m)), and the water storage level H _{( m)} (m = 1 to Y) indicates the water storage level (unit: (EL.m)), and the discharge flow rate Q _{(k, m)} depends on the opening G _(k) and the water storage level H _(m) . Shows the discharge flow rate. Hereinafter, a case where the current gate opening degree Gai is between the opening degree G ₍₅₎ and the opening degree G ₍₆₎ will be described as an example.

  The current discharge flow rate GQot is expressed by the following equation (1).

Since the gate opening degree Gai is between G ₍₅₎ and G ₍₆₎ , in equation (1), the discharge flow rates Q1 and Q2 of G ₍₅₎ and G ₍₆₎ at the water storage level Ha are expressed by (2) Calculated by the equation (3).
However, when all the gates 122 of each discharge device 12 are closed (when the control device 100 receives the closing signal), GQot = 0 is set regardless of the calculation result.

It is assumed that the reservoir level Ha of the reservoir 13 is between H ₍₅₎ and H ₍₆₎ .

Since the reservoir level Ha is between H ₍₅₎ and H ₍₆₎ , Q _(5,5) and H _{(6) in the case of} H ₍₅₎ and G ₍₅₎ in equation (2 _). calculating the discharge amount of G ₍₅₎ by using the Q _{(5, 6)} when a G ₍₅₎ and.

Since the reservoir level Ha is between H ₍₅₎ and H ₍₆₎ , Q _(6,5) and H _{(6) in the case of} H ₍₅₎ and G ₍₆₎ in equation (3 _). and calculates the discharge amount of G ₍₆₎ by using a Q _(6,6) when a G _(6).

<2> Calculation of the current discharge flow rate Qot in step S2 When the number of gates of each discharge device 12 is n, the current discharge flow rate Qot is expressed by the following equation (4).

<3> Calculation of ideal target discharge amount MQob in step S3 When a value for setting the discharge amount of the dam is input by the operator, based on the downstream discharge restriction table 40 so as not to cause a sudden change in the river level. To increase or decrease the current discharge flow rate Qot to calculate the ideal target discharge flow rate MQob.

FIG. 7 is a diagram (table) showing a downstream discharge restriction amount table.
The lower limit discharge limit table 40 has columns for a current discharge rate (unit: (m ³ / s)) and a column for an increase in discharge rate (unit: (m ³ / s)). The information arranged in the horizontal direction is associated with each other.

A value for dividing the current discharge flow rate Qot into fixed values is set in the current discharge flow rate column.
In the column for increasing the discharge flow rate, an increase amount for the discharge flow rate every 10 minutes based on the value set in the current discharge flow rate column is set. For example, when the current discharge flow rate Qot is “0.00 to less than 5.00”, the discharge flow rate can be increased only by “1.00” in 10 minutes, but when the current discharge flow rate Qot is “10.01−” Can increase the discharge flow rate by “5.00” in 10 minutes.

<4> Calculation of control target gate opening G in step S4 In order to discharge the calculated ideal target discharge flow rate MQob, the discharge flow rate is increased or decreased at the gate that is opened and closed with priority, and the flow rate close to that flow rate. Is calculated from the water storage level-opening-discharge flow rate table 30 described above to obtain the target opening G for each gate. Specifically, the ideal target discharge flow rate MQob can be obtained as much as possible from the storage water level H _(m) corresponding to the storage water level Ha and the discharge flow rate Q _{(k, m)} corresponding to the ideal target discharge flow rate MQob obtained in <3>. A target opening G that is a close value and does not exceed the ideal target discharge flow rate MQob is uniquely determined for each gate.

  Next, the target opening degree monitoring operation performed by the control monitoring unit 140 will be described. This operation is performed, for example, when the control calculation unit 130 determines the target opening degree G or every minute after the control calculation unit 130 outputs the target opening degree G to each discharge device 12 to be controlled.

FIG. 8 is a flowchart showing the target opening degree monitoring operation.
First, the current discharge flow rate GQot and the current discharge flow rate Qot for each gate calculated by the arithmetic processing unit 120 are read, and the ideal target discharge flow rate MQob and each target opening degree G calculated by the control calculation unit 130 are read (step S11).

  Next, each discharge device to be controlled using each target opening G, current water storage level Ha, water storage level-opening-discharge flow rate table 30, formula (1), formula (2), and formula (3). 12, the control target gate target total discharge flow ΣGQob when each target opening degree G is applied to 12 is calculated. Then, a difference ΔQ between the calculated control target gate target total discharge ΣGQob and the control target gate current total discharge ΣGQot is obtained (step S12). This difference ΔQ is a positive value when the current discharge flow rate is increased, and is a negative value when the current discharge flow rate is decreased.

Next, it is determined whether or not the ideal target discharge flow rate MQob is larger than the current discharge flow rate Qot (step S13).
If the ideal target discharge flow rate MQob is larger than the current discharge flow rate Qot (the current discharge flow rate is increased) (Yes in step S13), whether or not the sum of the current discharge flow rate Qot and the difference ΔQ is smaller than the current discharge flow rate Qot, Then, it is respectively compared whether or not the sum of the current discharge flow rate Qot and the difference ΔQ is larger than the ideal target discharge flow rate MQob (step S14).

When the condition of step S14 is not satisfied (No in step S14), it is determined that the target opening is normal, and the target opening monitoring operation is terminated.
On the other hand, if the condition of step S14 is satisfied, that is, if the current discharge flow rate Qot becomes small despite adding the difference ΔQ, or if the difference ΔQ is added to the current discharge flow rate Qot, the ideal target discharge flow rate MQob is exceeded. If this is the case (Yes in step S14), it is determined that the target opening is abnormal, and a control stop instruction is transmitted to each discharge device 12 to be controlled (step S15).

  In step S13, when the current discharge flow rate Qot is greater than or equal to the ideal target discharge flow rate MQob (No in step S13), it is determined whether the current discharge flow rate Qot is larger than the ideal target discharge flow rate MQob (step S16). .

  If the ideal target discharge flow rate MQob is smaller than the current discharge flow rate Qot (decrease the current discharge flow rate) (Yes in step S16), whether or not the sum of the current discharge flow rate Qot and the difference ΔQ is larger than the current discharge flow rate Qot, Then, it is respectively compared whether or not the value obtained by adding the difference ΔQ to the current discharge flow rate Qot is smaller than the ideal target discharge flow rate MQob (step S17).

When the condition of step S17 is not satisfied (No in step S17), it is determined that the target opening is normal, and the target opening monitoring operation is terminated.
On the other hand, when the condition of step S17 is satisfied, that is, when the current discharge flow rate Qot becomes small despite the addition of the difference ΔQ, or the difference ΔQ is added to the current discharge flow rate Qot to exceed the ideal target discharge flow rate MQob. When it has stopped (Yes in step S17), it is determined that the target opening is abnormal, and a control stop instruction is transmitted to each discharge device 12 to be controlled (step S15).

On the other hand, when the current discharge flow rate Qot and the ideal target discharge flow rate MQob are equal (No in step S17), the increment ΔQ ⁺ and the decrease amount are calculated using the equation (1) and the water storage level-opening-discharge flow rate table 30. ΔQ ⁻ is calculated (step S18). The increase ΔQ ⁺ and the decrease ΔQ ⁻ are expressed by Expression (5) and Expression (6), respectively.
ΔQ ⁺ : ΣGQob ⁺ −ΣGQot (5)
ΔQ ⁻ : ΣGQob ⁻ −ΣGQot (6)
Here, ΣGQob ⁺ indicates the current gate opening +1 (1 cm or 1%) of each discharge device 12 to be controlled, and ΣGQob ⁻ indicates the current gate opening −1 (−) of each discharge device 12. 1 cm or -1%).

Next, whether or not the discharge flow rate obtained by adding the increase ΔQ ⁺ to the current discharge flow rate Qot is smaller than the ideal target discharge flow rate MQob, and the discharge flow rate obtained by adding the decrease ΔQ ⁻ to the current discharge flow rate Qot is the ideal target discharge flow rate MQob. It is compared whether it is larger than each (step S19).

If the condition of step S19 is not satisfied (No in step S19), it is determined that the target opening is normal, and the target opening monitoring operation is terminated.
On the other hand, when the condition of step S19 is satisfied, that is, when the discharge flow rate obtained by adding the increase ΔQ ⁺ to the current discharge flow rate Qot becomes smaller than the ideal target discharge flow rate MQob, or the decrease ΔQ ⁻ is added to the current discharge flow rate Qot. When the released discharge flow rate becomes larger than the ideal target discharge flow rate MQob (Yes in step S19), it is determined that the target opening is abnormal, and a control stop instruction is transmitted to the discharge device (step S15).

This completes the target opening degree monitoring operation.
By the way, in step S12, an erroneous instruction may be transmitted to each discharge device 12, for example, the control calculation unit 130 transmits the target opening degree G to the discharge device 12 that is not a control target due to a program error. In this case, the control target gate target total discharge flow ΣGQob is generally a value separated from the ideal current discharge flow rate MQob. At this stage, the control monitoring unit 140 may transmit a stop instruction. However, steps S13 to S19 are further performed, and as a result, the value is as close as possible to the ideal target discharge flow rate MQob and exceeds the ideal target discharge flow rate MQob. If no flow rate is secured, the stop instruction is not transmitted, and as a result, excessive discharge can be prevented.

  Normally, when the ideal target discharge flow rate MQob calculated by the control calculation unit 130 is equal to the current discharge flow rate Qot, it is not necessary to operate each discharge device 12. However, in general, in a dam, the target opening of the gate of the discharge device to be operated is calculated in consideration of the priority order of the gate to be operated, the discharge device that does not operate due to a failure or the like. Therefore, the target opening value to be instructed and the discharge device to be controlled are changed. Therefore, normally, when the ideal target discharge flow rate MQob and the current discharge flow rate Qot are equal, the target opening degree monitoring operation is ended, and for the operations after No in step S16, for example, the priority order of the gates to be operated is different. Alternatively, it may be performed only when it is desired to perform discharge with correct gate priority. Accordingly, overdischarge can be prevented even when the gate opening degree or the discharge device to be controlled is changed when operation according to the discharge rule is performed.

9 to 11 are diagrams showing examples of the target opening degree monitoring operation shown in FIG.
As shown in FIG. 9, when the ideal target discharge flow rate MQob is larger than the current discharge flow rate Qot, if the current discharge flow rate Qot = 10 m ³ / s and the ideal target discharge flow rate MQob = 20 m ³ / s, the current discharge flow rate Qot when the sum of the difference ΔQ is not in the range of 10m ³ / s~20m ³ / s, it is determined that the target opening is abnormal.

As shown in FIG. 10, when the ideal target discharge flow rate MQob is smaller than the current discharge flow rate Qot, if the current discharge flow rate Qot = 10 m ³ / s and the ideal target discharge flow rate MQob = 5 m ³ / s, then the current discharge flow rate Qot when the sum of the difference ΔQ is not in the range of 5m ³ / s~10m ³ / s, it is determined that the target opening is abnormal.

As shown in FIG. 11, when the current discharge flow rate Qot = ideal target discharge flow rate MQob = 10 m ³ / s, 10 (m ³ / s) + increase ΔQ ⁺ <10 (m ³ / s) or 10 (m ³ / s) + decrease ΔQ ⁻ > 10 (m ³ / s), it is determined that the target opening is abnormal.

  As described above, according to the control device 100, after calculating the target opening degree G of each discharge device 12 from the ideal target discharge flow rate in the water supply flow to be supplied downstream or the discharge by flood control at the time of flood, The monitoring unit 140 monitors the correctness of each target opening G by a separate process, and transmits a stop instruction when an error is found, so that the discharge device 12 starts discharging at the given target opening. Since the discharge can be stopped, it is possible to prevent erroneous discharge, particularly overdischarge.

Further, for example, overdischarge can be more reliably prevented as compared with a control device or the like that performs feedback control in which it is impossible to determine whether or not the target opening is incorrect unless it is discharged once.
In this embodiment, one discharge device 12 has one gate 122, but one discharge device 12 may have a plurality of gates 122.

  As mentioned above, although the control apparatus and control program of this invention were demonstrated based on embodiment of illustration, this invention is not limited to this, The structure of each part is arbitrary structures which have the same function. Can be substituted. Moreover, other arbitrary structures and processes may be added to the present invention.
