Description

FIELD OF THE INVENTION

The invention relates to power supply systems of electric networks and distribution of electric energy, in particular to block electric stations for servicing AC networks, and can be used as a backup or emergency source of power supply.

The well-known "Mobile power station" is protected by the RF patent for invention No. 2295189 (IPC H02J 3/38, H02J 9/06, published on March 10, 2007, application No. 20055132860 dated October 26, 2005). Known mobile power plant contains two power units, each of which includes a power plant as part of an engine, functional technological systems, a frequency correction unit, a sensor unit, an actuator unit and a parameter control unit, a generator complex comprising an alternating current generator, voltage correction unit, voltage regulator, unit control panel, switching device consisting of three switches, input circuit, two consumer power lines and a power line o external network management network control unit of the automated system of emergency control including a unit of information collection and processing unit, a station, a computer system and a data transmission unit to which are connected the communication link from the superior control system. A well-known power plant increases the reliability of power supply to consumers. But a well-known power plant does not contain a fire extinguishing system among functional technological systems, which reduces its fire safety.

The well-known "Container for power, control and auxiliary electrical equipment of the upper power drive of the drilling rig" according to the patent of the Russian Federation for utility model No. 167726 (IPC B65D 88/74, G12B 9/00, Н05К 5/00, publ. 10.01.2017, application No. 2016102756 dated January 27, 2016). Known container for power, control and auxiliary electrical equipment of the upper power drive of the drilling rig, contains a base with all-welded frame with a roof and compartments. The base of the container is made in the form of a welded frame with a metal sheet rigidly mounted on it, which is mounted indented from the supporting surface. In this case, the frame is divided into insulated and non-insulated compartments. The uninsulated compartment is lower in height than the insulated compartment, and at least one vent fungus is placed in this drop. The well-known technical solution provides increased reliability of the structure, improved maintainability by providing convenient access for installation, dismantling and maintenance of the electrical equipment installed in it, in improving the thermal insulation of the internal volume of the container when the outside temperature changes (from + 45 ° C to -60 ° C) , to increase the safety of equipment during its transportation. However, the known container provides the placement of only electrical equipment intended for the top power drive of the drilling rig, and does not allow you to place power sources, the power plant in the form of a diesel generator unit with a gas exhaust and fuel system,

As the closest analogue, “Block-complete automated power plant” can be adopted according to the patent of the Russian Federation for utility model No. 167363 (IPC H02J 3/00, published on January 10, 2017, application No. 2015144452 dated October 15, 2015). According to the specified patent, the well-known block-complete automated power plant contains a warmed block box with ventilation openings with air valves, airtight entries in the end walls for docking with other block containers. It consists of two compartments, aggregate and control, equipped with separate inputs. In the first aggregate compartment, a redundant external power source is fixed in the form of a high-power diesel generator, a fuel tank, a fuel oil tank, batteries, electric air valves for electric air supply, electric air valves for heat dissipation. In the second compartment, a shield of own needs is fixed, connected with a generator shield. In this case, the power input busbars from the diesel generator are connected through the generator circuit breaker with the output busbars of the generator shield to the complete transformer substation, which is connected to the main external power supply to provide voltage supply and shutdown.

The well-known solution of the closest analogue provides uninterrupted power to consumers of electricity, not allowing a break in the power supply (consumers). But the known solution does not ensure the safety of the power plant due to the placement of the diesel generator and the fuel tank in the same zone close to each other. In addition, the mount of the diesel generator does not contain anti-vibration devices, and the gas exhaust system is not equipped with a bellows compensator and a removable silencer, which does not reduce the noise of the diesel generator.

In FIG. 1 shows the design of BAECT and the layout of its equipment.

Structurally, the BAEKT includes a housing 1 in the form of a container block module, a power plant, which can contain one or a group of diesel generator units 5 and a gas exhaust system, a fuel system, technological and general ventilation equipment, air heating equipment, a main and emergency power supply system , a system of basic and emergency electric lighting and a fire extinguishing system and burglar alarm.

The housing has a doorway 4, openings of ventilation hatches, openings and channels, including cable channels 33, channels for mounting gas exhaust elements, fuel supply channels of the fuel system. Inside the body of the wall 3 and the ceiling are made heat and noise insulated using material, for example, mineral wool and sheathed with steel profiled sheet. Floor 2 of the housing is equipped with a frame 6 for mounting the diesel generator unit 5 and a crate made of a channel, filled with heat and noise insulation material, for example, in the form of mineral wool, and welded with a corrugated metal sheet. The walls 3 and the ceiling of the housing 1 are provided with drain holes and grooves for draining accidentally spilled technical fluids. In addition, cable channels are placed inside the housing on floor 2 and walls 3 and are made of non-combustible material: metal on the floor and plastic on the walls. At the same time, the holes made are equipped with glands for cable passage.

The diesel generator unit 5 is placed inside the housing near the end wall 3, opposite the end wall 3, equipped with a doorway 4. It is mounted on the frame 6, which is a power frame, by means of attachment points 7 (see Fig. 2 and Fig. 3), equipped with anti-vibration devices. Anti-vibration devices are made in the form of pillows, which are made of plastic material in a hemispherical or cylindrical shape, or in a combination of the above forms, and the eyes of the attachment points 7 of the diesel generator set 5. The pillows and eyes of the anti-vibration devices of the attachment points 7 of the diesel generator set 5 reduce the level noise, the likelihood of breakdowns and accidents, and increase the safety and life of the diesel generator set.

At the same time, the diesel generator unit 5 is equipped with an electric generator with a voltage regulator, an electric generator shield 28 and an electronic control panel 29. The electric generator provides external power supply. The electronic control panel 29 is configured to automatically control the diesel generator unit 5.

The gas exhaust system includes an exhaust pipe 10 with thermal insulation, a bellows expansion joint 11 and a silencer 12. The silencer 12 is mounted on brackets on the outside of the end wall 3 of the housing with the possibility of dismantling in the transport and installation in the working position.

The fuel system includes a supply tank 13, which is equipped with a fuel level sensor 19, an oil tank, direct and return fuel lines 15 and 16, a filler neck 17, a manual fuel transfer pump 18. The filler neck 17 enters one of the ends of the consumable tank 13 and the other inlet end is installed on the wall 3 of the housing and is equipped with a fueling hatch with a lid. A manual pump for transferring fuel 18 to a supply tank 13 from external containers is installed on the direct fuel line 15. The inlet end of the direct fuel line 15 is installed on the wall 3 of the housing and is equipped with a hatch with a lid. The consumable tank 13 is made with a pallet 14, is equipped with a fuel level sensor 19, is located near the doorway 4 inside the housing and is connected to the direct and return fuel lines 15 and 16. The fuel lines are laid along the fuel supply channels of the floor 2 of the body and are protected by a metal box, which increases the fire protection of BAECT .

Ventilation and air heating equipment is located in the area of the diesel generator unit 5. It includes a supply universal air valve 22 with an electric actuator 24 and an exhaust universal air valve 23 with an electric actuator 24, an exhaust duct fan 25, an electric heater 26, air temperature sensors 27, and temperature regulators. Universal air valves and duct fans are installed in openings outside the housing. At the same time, it is possible to install a group of universal air valves and duct fans in the housing, depending on the dimensions of the BAEKT housing. Apertures 20, 21 of universal air valves and duct fans are equipped with metal grilles and protective covers. The protective covers are open in the working position and closed in the transport position.

The main and emergency power supply system consists of an auxiliary shield 30, a battery 31, sockets with main 220 V and emergency 12 power lines 32, 33, power and control cables. The auxiliary shield 30 is equipped with elements for automatic control of the main and emergency power supply. It contains control circuits for ventilation and heating equipment, the internal electrical system of the electric lighting system, lines and sockets of power supply to consumers. The battery 31 is mounted on the frame 6 of the diesel generator unit. It is electrically connected to the auxiliary needs panel 30 and provides emergency internal power supply to BAEKT. In this case, the main and emergency power supply system may include one or a group of batteries for reliable and uninterrupted power supply. Sockets with main and emergency power supply lines 32, 33 are powered from the auxiliary needs panel 30 and provide power to consumers. Power and control cables of the main and emergency power supply systems are connected on one side with the auxiliary shield 30 and on the other with elements of the diesel generator unit 5. They are laid in the floor 2 and walls 3 of the building through openings and in channels made of non-combustible material. The auxiliary shield 30, the shield of the power generator 28 and the electronic control panel 29 are located on the wall 3 of the housing close to each other. While the shield of own needs 30 is electrically connected to the shield of the generator 28.

The main and emergency electric lighting system consists of switches and fixtures of the internal power supply network installed inside the BAEKT housing. The switches 35 and the lamps 37 of the main electric lighting are powered through the auxiliary needs panel 30 from the electric generator, and the switches 36 and the lamps 38 of the emergency electric lighting are supplied from the battery 31.

The fire extinguishing and security alarm system includes a control fire and security device 39 (OPP), a remote start-up, a group of electrically connected fire detectors, security sensors, information lines of fire and security alarms, sound and light annunciators, fire extinguishing module 40 (MPT) and a group of fire extinguishers 41.

BAECT works as follows.

On the basis of remote control signals, either from external devices for automatic input of backup power supply, or from a switch on the electronic control panel of the diesel generator set, the diesel generator set is started and stopped.

During the operation of the diesel generator set, the frame on which the diesel generator set is mounted perceives and withstands bending and torque moments from it. The pillows and eyes of the anti-vibration devices of the fasteners of the diesel generator set, made on the frame, significantly reduce the impact on the body of vibration. At the same time, noise and the likelihood of breakdowns and accidents are reduced, the work safety and the service life of the diesel generator set are increased. The silencer also provides a gas exhaust silencer when exhaust gases are exhausted from a diesel generator set. At the same time, the bellows compensator compensates for the extension effects on the exhaust pipe of the temperature and pressure of the exhaust gases and reduces the likelihood of malfunctions of the gas exhaust system. If it is necessary to transport to another place where external power supply is connected, the BAEKT is brought into the transport position, in which the muffler is removed to ensure the safety of the BAEKT transportation. When brought into working position, the muffler is reinstalled on the brackets on the outside of the end wall of the BAECT housing.

Connection of the load to the electric generator and external power supply from it is carried out on command from the electronic control panel of the diesel generator unit.

The diesel generator set is supplied with fuel from the supply tank, the tank fuel level sensor is connected to the electronic control panel of the diesel generator set and generates signals: “Fuel level for two hours of operation”, “Emergency fuel level”. The first signal is transmitted from the electronic control panel of the diesel generator set to an external monitoring system, the second signal leads to an emergency stop of the diesel generator set. The fuel tank is replenished with a manual fuel transfer pump through a hatch with a lid from external containers.

When the diesel generator set is idle, the BAECT auxiliary supply systems are supplied from external sources of power supply.

When the diesel generator set is started, the supply air universal valve opens, and when the air temperature in the BAECT housing is above plus 25 ° C, the exhaust universal air valve of the technological ventilation equipment automatically opens. In case of reaching air temperature plus 50 ° С, an alarm is generated in the auxiliary panel to stop the diesel generator unit.

If the “Winter - Summer” switch located in the auxiliary needs panel is in the “Winter” position and the temperature in the BAEKT case has dropped below + 10 ° С, the group of electric heaters of the air heating equipment is automatically turned on. When the diesel generator unit is running, the operation of the air heating equipment is blocked. When the “Summer - Summer” switch is in the “Summer” position and the temperature in the BAECT housing rises above + 25 ° С, the general ventilation equipment is turned on - the supply and exhaust universal air valves open and the retractable duct fan is turned on. It is possible to force the general ventilation equipment to be switched on with the help of a toggle switch installed on the auxiliary needs panel. When the diesel generator unit is running, the operation of general ventilation equipment is blocked.

Emergency light fixtures receive power from the battery during emergency power supply.

In the event of a fire, the fire extinguishing and burglar alarm system gives a command to stop the diesel generator unit and to deenergize the BAECT electrical equipment.

Thus BAECT ensures low noise operation, increases safety and reliability, both in the working position and during its transportation by various modes of transport.

For the implementation of BAECT use standard materials and industrial equipment of manufacturing enterprises, which indicates the industrial applicability of the proposed technical solution.
