Fig. 4 is a flowchart illustrating a method for displaying index information of a wind farm according to another exemplary embodiment, where the method for displaying index information of a wind farm may be applied to an index information display system, where a fan device, a wind farm, and a computer device are present, and the method is performed by the computer device. For example, the fan apparatus may be any of the fan apparatuses 110 shown in fig. 1, the wind farm may be any of the wind farms 120 shown in fig. 1, and the computer apparatus may be the computer apparatus 130 shown in fig. 1. As shown in fig. 4, the method for displaying index information of a wind farm may include the following steps:

in step 401, a computer device obtains historical data information for at least one fan device in a wind farm.

In the embodiment of the disclosure, the computer device may collect the historical data information of at least one fan device monitored by the computer device through a special system for wind farm data collection.

Wherein the historical data information includes operational data information and time data information, the wind farm being comprised of the at least one wind turbine device. The history data information includes power generation amount information, and time information in each power generation state, wherein the power generation amount information includes: the actual power generation amount and the theoretical power generation amount of the corresponding fan; the time information includes: total time, no connection time, no calculation time, and unavailable time.

Alternatively, the computer device may sample data in the SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control system), and the obtained sampled data is the historical data information.

Alternatively, the user may enter a time frame in the private system, which is a period of time that requires querying the historical data information.

For example, if the user needs to evaluate the running condition of the fan equipment in 10 th month 1 of 2019 and the power generation condition of the wind farm, inputting 0 point in 10 th month 1 of 2019 to 0 point in 10 th month 2 of 2019 as a time range in the special system, and querying the actual power generation amount and the theoretical power generation amount of each fan equipment which can be monitored by the computer equipment in the time range, and the connectionless time, the uncomputed time and the unavailable time of each fan equipment in the running process. According to the obtained historical data information of each fan device, the actual power generation amount and the theoretical power generation amount of the whole wind power plant formed by each fan device can be obtained, and the average connectionless time, the average non-calculation time and the average unavailable time of the wind power plant in the production process can be obtained.

In step 402, the computer device determines power generation index information for the at least one fan device, and power generation index information for the wind farm, based on historical data information for the at least one fan device.

In the embodiment of the disclosure, the computer equipment determines index information of each fan equipment according to at least one data information of actual power generation amount, theoretical power generation amount, connectionless time, non-calculation time and unavailable time of each fan equipment, and determines index information of a wind farm formed by each fan equipment according to historical data information of each fan equipment.

The power generation index information comprises at least one of energy availability EBA, time availability TBA and lost electric quantity. The method for determining three power generation index information according to the historical data information of each fan device is as follows:

1) The power generation index information is the energy availability EBA

Optionally, when the index information at least includes the energy availability EBA, the actual power generation amount of each fan device is compared with the theoretical power generation amount to obtain the energy availability EBA of each fan device, and the sum of the actual power generation amounts of the at least one fan device and the theoretical power generation amount of the at least one fan device in the wind farm is compared to obtain the energy availability EBA of the wind farm.

Wherein eba= (actual power generation amount of the fan apparatus)/(theoretical power generation amount of the fan apparatus). Eba=sum (actual power generation per fan in the wind farm)/sum (theoretical power generation per fan in the wind farm).

For example, when the actual power generation amount of the fan apparatus is a and the theoretical power generation amount of the fan apparatus is B, eba=a/B of the fan apparatus. When a wind farm includes three fan devices, and the actual power generation amounts are C, D and E, respectively, and the theoretical power generation amounts are F, G and H, EBA of the wind farm is (c+d+e)/(f+g+h).

The energy availability EBA of the wind power plant is index information used for measuring the production efficiency of the wind power plant, and the larger the EBA value is, the higher the power generation efficiency of the wind power plant is.

2) The power generation index information is the time availability TBA

Optionally, when the index information at least includes the time availability TBA, comparing a difference value between the total time, the unavailable time and the non-calculated time of each fan device with a difference value between the total time and the non-calculated time of each fan device to obtain a time availability TBA of each fan device, and taking the unavailable time of the at least one fan device in the wind farm as an average value to obtain an unavailable time average value; averaging the non-calculated time of the at least one fan device in the wind farm to obtain a non-calculated time average; and comparing the difference value between the total time and the first time average value with the difference value between the total time and the non-calculated time average value to obtain the time availability TBA of the wind power plant, wherein the first time average value is the sum of the non-available time average value and the non-calculated time average value.

Wherein tba= (total time-available time-not calculated time)/(total time-not calculated time) of the fan device. Eba=1 of the wind farm-average of time unavailable to each fan device in the wind farm/(total time-average of time not calculated by each fan device in the wind farm).

Wherein, no calculation time = no connection state time caused by non-faulty shutdown and non-maintenance shutdown + manual shutdown time caused by non-maintenance and fault.

For example, fig. 5 is a schematic diagram of a time range corresponding to a non-faulty shutdown of a fan apparatus according to the present embodiment, and the non-connection state of the fan apparatus is divided into two types, one type is a non-connection state time caused by the non-faulty shutdown and the non-maintenance shutdown, and the other type is a non-connection time caused by the faulty shutdown. Wherein, the connectionless state time caused by non-fault shutdown and non-maintenance shutdown = the connectionless time caused by maintenance shutdown-the connectionless time caused by fault shutdown within the time range, wherein, the connectionless time = the unknown state time + the connectionless state time, the state of the operation process of the fan device and the corresponding time range are as shown in fig. 5, the sum of the unknown state and the connectionless state time equals the connectionless time, the connectionless time = t2+t3+t4+t6.

The connectionless time caused by the shutdown is a time when the state of the fan apparatus immediately after the shutdown state is an unknown state or a connectionless state until the state of the fan apparatus becomes the unknown state and the connected state, as the connectionless time caused by the shutdown. For example, as shown in fig. 5, the connectionless time=t2+t3+t4 caused by the failed shutdown.

Similarly, fig. 6 is a schematic diagram of a time range corresponding to a non-maintenance shutdown of a fan apparatus according to the present embodiment, in which the non-connection time caused by the maintenance shutdown is the non-unknown state or the non-connection state of the fan apparatus immediately after the maintenance shutdown state, until the state of the fan apparatus becomes the non-unknown state and the connection-present state, which is the non-connection time caused by the maintenance shutdown. For example, as shown in fig. 5, the connectionless time=t2+t4+t5 caused by maintenance stoppage.

In addition, the non-maintenance and non-failure induced manual downtime = statistical time range in which the fan status is the time of manual downtime-maintenance downtime-failure downtime. Fig. 7 is a schematic diagram of a time range corresponding to a non-maintenance and non-failure-induced manual shutdown according to the present embodiment, as shown in fig. 7, manual shutdown time=t2+t5+t7. Wherein the manual downtime caused by the maintenance downtime is a time range in which the state immediately after the maintenance downtime is a manual downtime until the fan state is a non-manual downtime state, for example, as shown in fig. 7, the manual downtime caused by the maintenance downtime=t2. The state immediately after the fail-stop-caused manual stop time is a manual stop until the fan apparatus state is a time range of the non-manual stop state, for example, as shown in fig. 7, the fail-stop-caused manual stop time=t7.

The time availability TBA of the wind power plant is index information used for measuring the normal working time of a generator set of the wind power plant, and the larger the TBA value is, the higher the power generation efficiency of the wind power plant is.

3) The power generation index information is the lost electric quantity

Optionally, when the index information at least comprises the lost electric quantity, taking the sum of theoretical generated energy in a fan fault shutdown time range and a fan maintenance time range as the fan fault lost electric quantity; the sum of theoretical power generation capacity and actual power generation capacity in the power limiting operation and power limiting shutdown time range of the fan are subjected to difference value, and the power loss electric quantity of the fan is determined; taking the sum of the fan fault loss electric quantity and the fan limited power loss electric quantity as the loss electric quantity of the fan equipment; and determining the lost electric quantity of the wind farm according to the lost electric quantity of the fan equipment.

Wherein, fan fault loss electric quantity=theoretical generated energy in the fan fault shutdown and fan maintenance time range, fan electricity limiting loss electric quantity=theoretical generated energy-actual generated energy during fan power limiting operation and power limiting shutdown. Lost power of fan equipment = fan electricity limiting lost power + fan fault lost power.

Wherein, the full wind farm electricity limiting loss electricity quantity=max (sum of full wind farm fan theoretical electricity quantity within the full wind farm electricity limiting time range-power limiting set value time, 0); full wind farm fan fault loss electric quantity=min (min (sum of full wind farm fan theoretical electric energy generation amount, full wind farm power limit electric energy) -sum of full farm fan actual electric energy generation amount), sum of full wind farm fan fault shutdown loss electric quantity; full wind farm lost electricity = full wind farm electricity limiting lost electricity + full wind farm fault lost electricity.

The lost electric quantity of the wind power plant comprises the lost electric quantity of the fan equipment in the fault, power limit and full-field power limit states, and is mainly used for analyzing index information of the cause of the fault of the fan equipment of the wind power plant, and the smaller the lost electric quantity value is, the higher the power generation efficiency of the wind power plant is.

In step 403, the computer device determines, according to the time information in the historical data information of the at least one fan device, the respective credibility of the power generation index information of the at least one fan device and the power generation index information of the wind farm.

In the embodiment of the disclosure, in order to increase the actual credibility of each index information, the computer device sets different credibility calculation methods for each index information, and calculates the credibility of each index information according to the time data information.

The reliability is used for representing the difference between the running condition and the actual running condition of the fan equipment and the wind farm displayed by the index information.

Alternatively, the larger the value of the credibility is, the smaller the difference between the calculation result of the corresponding index information and the actual running condition is.

The calculation method for determining the reliability of the index information energy availability EBA, the time availability TBA and the lost electric quantity is as follows:

1) Reliability of energy availability EBA

Optionally, the computer device obtains the EBA credibility of each fan device according to the ratio of the connectionless time to the total time of each fan device, and obtains the EBA credibility of the wind farm according to the ratio of the average value of the connectionless time to the total time of the at least one fan device.

Optionally, the reliability of the energy availability EBA is determined by the connectionless time.

Wherein, the reliability of EBA index=1-connectionless time/total time. Wind farm EBA reliability = 1-average/total time of fan equipment connectionless time under the wind farm.

2) Reliability of time availability TBA

Optionally, the computer device obtains the reliability of the TBA of each fan device according to the ratio of the non-calculation time to the total time of each fan device; and obtaining the TBA credibility of the wind power plant according to the ratio of the average value of the non-calculated time of the at least one fan device to the total time.

Optionally, the confidence level of the time availability TBA is determined by the non-calculation time.

Where the confidence level of the TBA indicator = 1-no time/total time calculated. Wind farm TBA reliability = 1-average/total time of fan non-calculated time under the wind farm.

3) Reliability of lost electric quantity

Optionally, the reliability of the lost power is determined by the connectionless time.

Where fan failure loses power reliability = 1-no connection time/total time due to fan failure. Fan limit power loss power confidence = 1-fan limit induced connectionless time/total time. Wind farm electricity limiting loss power reliability = 1-no connection time/total time. Wind farm fault loss power reliability = 1-no connection time/total time. Fan loss electric quantity reliability= (fan electricity limit electric quantity loss + fan fault reliability x fan fault electric quantity loss)/fan loss electric quantity; if the lost power is 0, the reliability is 1. Wind farm loss power reliability= (wind farm electricity limit reliability wind farm electricity limit loss power + wind farm fault reliability wind farm fault loss power)/wind farm loss power. If the lost power is 0, the reliability is 1. Total time = number of fans x statistical time range.

In step 404, the computer device displays the power generation index information of the at least one fan device, the power generation index information of the wind farm, and the reliability.

In the embodiment of the disclosure, the computer device may directly display each index information and the corresponding reliability on a display interface of the computer device, and the user may check and analyze the index information, or may set a predetermined weight for each index information, rank each fan device according to the power generation power according to the predetermined weight and the reliability, rank each wind farm according to the power generation power condition, and display the ranking result on the display interface.

Optionally, the computer device orders the fan device and the wind farm according to the power generation power conditions according to the preset weight and the corresponding credibility set by each power generation index information.

Fig. 8 is a schematic diagram of a page directly displayed on a page with EBA as an index and corresponding reliability, where, as shown in fig. 8, the page may be displayed in a form of a table, and includes historical data information such as actual power generation amount, theoretical power generation amount, connectionless time and the like required by calculating EBA, a control for selecting a time range, and a control for selecting a querying fan or a wind farm, and may be queried and derived.

Optionally, the computer device may rank by index weighting, and finally obtain a composite score, measure fan performance and wind farm efficiency by three indexes, and calculate the composite score.

For example, a user may set a weight w for each index, a fan composite score=w1×normalized eba+w2×normalized tba×tba reliability+w3×normalized lost power×lost power reliability, where w1+w2+w3=1, the EBA of the normalized fan= (current fan EBA-query minimum EBA)/(query maximum EBA) query minimum EBA of all fans), the normalized TBA and EBA, and the normalized lost power=1- (current fan lost power-query minimum lost power)/(query maximum total fan minimum lost power), and finally obtain a composite score. Similarly, the method can be applied to wind power plants, the comprehensive score of each wind power plant is calculated, and each wind power plant is compared.
