[0038] In one embodiment, each power equipment of the corresponding group is provided with a sensor device, and the sensor device is used to detect the status parameters of each power equipment. The sensor device is communicatively connected with the control mechanism to transmit the detected status parameters of each power equipment to the control mechanism, so that the control mechanism can control each power equipment according to the status parameters of each power equipment transmitted by the sensor device.

[0039] In an optional embodiment, there are multiple units, and different units have their own corresponding unit numbers. On the basis of the unit number, each power device in the unit is further numbered according to different power devices, so as to be based on the unit number and the power device number. Optionally, the sensor device can be numbered according to the detected power device number. When the sensor device transmits the state parameters of the detected power device to the control device, the state parameters of the detected power device are numbered using the power device number, so that after receiving the state parameters of the power device, the control mechanism stores them according to the power device number, so that when it is used later, the parameters of the power device can be obtained according to the power device number. It is also possible to obtain the state parameters corresponding to each power device included in the mechanism according to the mechanism number.

[0040] Step 204, determining the current operating state of the unit to be processed according to the unit control state parameters, the unit outlet circuit breaker state parameters, the operating condition flow parameters, the unit operating speed and the switch closing state parameters.

[0042] Optionally, a preset state parameter may be set for each power device, and the current operating state of the unit to be processed may be determined by comparing the state parameter of each power device with the preset state parameter corresponding to each power device.

[0043] In an optional embodiment, corresponding preset parameters are obtained according to the unit number, and the preset conditions include preset unit control state parameters, preset unit output circuit breaker state parameters, preset operating condition process parameters, preset unit operating speed and preset switch closing state parameters.

[0044] Among them, the preset unit control state parameters are used to characterize the normal operation of the unit, the preset unit outlet circuit breaker state parameters are used to characterize the normal operation of the circuit breaker, the preset operating condition process parameters are used to characterize that the back-to-back dragging engineering process, the black start operating condition process and the line charging operating condition process are not running, the preset unit operating speed is used to determine the speed of the unit operation, and the preset switch closed state parameters are used to characterize that the switch is in an open state.

[0046] In one embodiment, the current operating state of the unit to be processed is determined according to the matching result of the state parameter of each power device with the preset state parameter corresponding to each power device. Optionally, when the unit control state parameter matches the preset unit control state parameter, the unit circuit breaker state parameter matches the preset unit circuit breaker state parameter, the unit transformer parameter matches the preset unit transformer parameter, the unit operating speed matches the preset unit operating speed, and the switch closing state parameter matches the preset switch closing state parameter, it is determined that the current operating state of the unit to be processed is an operating state that requires forced tripping.

[0047] In an optional embodiment, to improve practicality, when transmitting electric energy from the unit to the outside, a multi-way switch circuit can be set for the unit, for example, for unit 1, a switch circuit 1 and a switch circuit 2 can be set. Optionally, the switch circuit can include at least one switch, for example, the switch circuit 1 includes a switch YACL10 GS101 (5002), and the switch circuit 2 can include three switches YACL10 GS101 (5001), YACL10 GS101 (5003) and YACL10GS101 (5004).

[0048] Optionally, corresponding to switch line 1, when switch YACL10 GS101 (5002) is closed, unit 1 can realize external power transmission; corresponding to switch line 2, YACL10 GS101 (5001), YACL10 GS101 (5003) and YACL10 GS101 (5004) need to be closed to realize external power transmission.

[0049] Optionally, when there is only one switch in the external switching line, the preset switch closing state parameter is used to characterize that the switch is in an open state; when there are multiple switches in the external switching line, the preset switch closing state parameter is used to characterize that any switch is in an open state.

[0050] In an optional embodiment, multiple units can use the same switching line for external transmission. For example, when unit 1 and unit 2 realize external power transmission, they both use line 1 and line 2.

[0051] Optionally, different units may use different external transmission switch lines, for example, unit 1 and unit 2 use line 1 and line 2, while unit 3 and unit 4 use line 3 and line 4.

[0052] In one embodiment, when any one of the first matching result between the unit control state parameter and the preset unit control state parameter, the second matching result between the unit output circuit breaker state parameter and the preset unit output circuit breaker state parameter, the third matching result between the operating condition flow parameter and the preset operating condition flow parameter, the fourth matching result between the unit operating speed and the preset unit operating speed, and the fifth matching result between the switch closing state parameter and the preset switch closing state parameter does not match, it is determined that the current operating state of the unit to be processed is an operating state that does not require forced tripping. Optionally, when the current operating state of the unit to be processed is an operating state that does not require forced tripping, the corresponding power equipment when the matching result does not match can be obtained, an alarm signal is generated according to the power equipment, and the alarm signal is transmitted to the corresponding terminal device of the safety officer to provide the safety officer with a check.

[0053] In one embodiment, when the first matching result of the unit control state parameter and the preset unit control state parameter, the second matching result of the unit output circuit breaker state parameter and the preset unit output circuit breaker state parameter, the third matching result of the operating condition flow parameter and the preset operating condition flow parameter, the fourth matching result of the unit operating speed and the preset unit operating speed, and the fifth matching result of the switch closing state parameter and the preset switch closing state parameter all do not match, it can be considered that the unit to be processed is currently in normal operating state and the unit to be processed will not be processed.

[0054] Step 206: When the current operating state of the unit to be processed is a preset state, the unit to be processed is controlled to be forced to trip.

[0055] In an optional embodiment, a control signal may be set corresponding to the current operating state of the unit. For example, when the current operating state is a forced tripping state, the corresponding control signal is a forced tripping signal.

[0056] In one embodiment, after determining the current operating state of the unit to be processed, the current operating state is matched with a preset state. When the current operating state is determined to be the preset state, a corresponding control signal is obtained according to the preset state so that the unit to be processed can be controlled according to the control signal.

[0057] Optionally, when the current operating state of the unit to be processed is an operating state requiring forced tripping, a forced tripping control instruction is generated; the forced tripping control instruction is used to control the forced tripping of the unit to be processed.

[0058] Among them, the unit to be processed is controlled to be forced to trip according to the forced trip control instruction.

[0059] Optionally, when it is determined that the unit needs to be forced to trip, a forced trip instruction may be generated, and the unit may be controlled according to the forced trip instruction.

[0060] In one embodiment, a forced trip switch may be provided for the unit, and the forced trip switch is used to implement the forced tripping of the unit. Optionally, when the forced trip switch is disconnected, it indicates that the unit has been forced to trip. Optionally, the forced trip switch may be a 500kV switch.

[0061] In an optional embodiment, the forced tripping of the unit to be processed is controlled according to the forced tripping control instruction, including: determining the number of the corresponding forced tripping switch according to the unit number; and controlling the forced tripping switch corresponding to the number of the forced tripping switch to trip according to the forced tripping instruction.

[0062] Optionally, the intelligent switch includes a forced trip switch, and the forced trip switch is used to realize the forced tripping of the unit. Optionally, each power device included in the unit corresponds to its own forced trip switch, and a forced trip switch can also be set for the unit, so as to realize the control of the forced tripping of the entire unit by using a forced trip switch.

[0063] In one embodiment, when the current operating state of the unit is a state requiring forced tripping, it indicates that the unit needs to be forced tripped. Optionally, the forced tripping switch corresponding to the unit is obtained according to the unit number, and the forced tripping switch is controlled to operate to realize the forced tripping of the unit. Optionally, the forced tripping switch operation can be controlled to disconnect the forced tripping switch, and the forced tripping switch is set on the unit bus. When the forced tripping switch is in the disconnected state, it indicates that the unit has been forced to disconnect.

[0064] Optionally, the forced trip switches corresponding to the units may be numbered based on the unit number, so that when it is determined that the unit needs to be forced to trip, the corresponding forced trip switch is determined according to the unit number, and the forced trip switch is controlled to be disconnected to achieve forced tripping of the unit.

[0065] In one embodiment, a forced trip instruction is used to control the forced trip switch corresponding to the unit to be disconnected, so as to achieve forced tripping of the unit.

[0066] In an optional embodiment, it is detected whether the information of forced tripping corresponding to other units transmitted by other units is received; if so, the number of times the information of forced tripping corresponding to other units transmitted by other units is received is determined; when the number of times the information of forced tripping corresponding to other units is greater than or equal to a preset number, a forced tripping instruction is generated, and the forced tripping of the unit to be processed is controlled according to the forced tripping instruction.

[0067] In one embodiment, there may be multiple sets, and optionally, there are at least three sets.

[0068] In one of the embodiments, when there are at least three units, a linkage mechanism can be set between the units. However, when multiple units have been forced to trip, the current unit to be processed is also forced to trip.

[0069] Optionally, on the server side, a detection thread may be set for each unit to detect whether the current unit has received the forced tripping information corresponding to other units, and the number of times the forced tripping information corresponding to other units has been received.

[0070] Optionally, after a forced trip command is generated for a certain unit, forced trip information is generated based on the forced trip signal and sent to other units except the certain unit.

[0071] In one embodiment, when the server sends the forced tripping information corresponding to the unit, it performs statistics on the sending unit. When the number of statistics is greater than or equal to a preset number, a forced tripping instruction is generated for the unit, and the unit is controlled to be forced to trip according to the forced tripping instruction.

[0072] Optionally, a detection thread may be provided on the unit side to detect whether information on forced tripping of other units has been received, and when it is detected that information on forced tripping of other units has been received, the number of times the information on forced tripping of other units has been received is counted.

[0073] Optionally, when the number of times is greater than a preset number of times, a forced tripping instruction may be generated by a control mechanism on the unit side, and the unit may be controlled to forced trip according to the forced tripping instruction.

[0074] In an optional embodiment, the units are connected to each other in communication, and the information of forced tripping corresponding to other units can also be sent by other units.

[0075] In the above-mentioned unit control method, when the unit control is realized, the current operating state of the unit is determined according to the unit control state parameters in the unit line, the unit outlet circuit breaker state parameters, the working condition process parameters, the unit operating speed and the switch and state parameters, and the unit is controlled according to the current operating state of the unit. The control of the unit using multiple parameters can effectively ensure the accuracy of the unit control, so that when disconnection occurs, it can effectively ensure that the unit can trip accurately and timely, and effectively ensure the safety of the unit.
