Description

Technical Field

[0001] This application relates to the field of smart grid technology, and in particular to a unit control method, apparatus, computer equipment, computer-readable storage medium, and computer program product. Background Technology

[0002] Currently, power stations or power plants use a single outgoing line to transmit electricity. When this only outgoing line breaks, a signal must be immediately sent to trip the operating generator to ensure its safety. If the generator cannot trip immediately, it can only rely on overspeed protection to trip during power generation, which cannot effectively guarantee the generator's safety. Therefore, the current generator control method cannot effectively guarantee the generator's safety. Summary of the Invention

[0012] In one embodiment, the method further includes: detecting whether information of forced tripping corresponding to other units is received from other units; if so, determining the number of times information of forced tripping corresponding to other units is received from other units; when the number of information of forced tripping corresponding to other units is greater than or equal to a preset number, generating a forced tripping control command, and controlling the unit to be processed to forcibly trip according to the forced tripping control command.

[0013] Secondly, this application also provides a unit control device, comprising:

[0016] The trip control module is used to force the unit to trip when the current operating status of the unit meets the preset conditions.

[0017] Thirdly, this application also provides a computer device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps in the above-described method embodiments.

Utilizing multiple parameters to control the unit effectively ensures the accuracy of unit control, thereby ensuring accurate and timely tripping of the unit in the event of disconnection or other situations, effectively guaranteeing the unit's safety.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] The unit control method provided in this application embodiment can be applied to, for example, Figure 1In the application environment shown, unit 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or placed on a cloud or other network server. Sensors in unit 102 detect the status parameters of the electrical equipment included in the unit and transmit them to server 104. Server 104 obtains the unit number of the unit to be processed and retrieves the unit control status parameters, unit outlet circuit breaker status parameters, operating process parameters, unit operating speed, and switch closing status parameters in the corresponding unit line. Based on these parameters, server 104 determines the current operating status of the unit to be processed. When the current operating status of the unit to be processed is a preset state, the server forces the unit to trip. Unit 102 can include, but is not limited to, various intelligent power devices. Server 104 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0029] In one exemplary embodiment, such as Figure 2 As shown, a unit control method is provided, which is applied to... Figure 1 Taking the server in the example, the explanation includes the following steps 202 to 206. Wherein:

[0030] Step 202: Obtain the unit number of the unit to be processed, and obtain the unit control status parameters, unit outlet circuit breaker status parameters, operating process parameters, unit operating speed and switch closing status parameters in the unit circuit corresponding to the unit number.

[0031] Among them, the generator unit is an electrical equipment that converts other forms of energy (mechanical energy, hydraulic energy, etc.) into electrical energy for output.

[0032] Optionally, the unit may include, but is not limited to, control mechanisms, circuit breakers, transformers, intelligent switches, and sensing devices. Optionally, the control mechanism may include, but is not limited to, a PLC (Programmable Logic Controller) or other control servers; there is no limitation thereto.

[0033] The unit control status parameters are used to characterize the operating control signal parameters received by the unit from the control mechanism. Optionally, the control status parameters may include, but are not limited to, normal operation, forced trip, no operation, and black start status. Optionally, the black start status may include the unit being in a black start steady state, or the unit not being in a black start steady state.

[0034] The status parameters of the unit's outlet circuit breaker are used to characterize the operating status parameters of the unit's circuit breakers. Optionally, the status parameters of the unit's circuit breaker may include, but are not limited to, normal operation, abnormal operation, and no operation.

[0035] Operating condition process parameters are used to characterize the unit's operating condition parameters. Optionally, operating condition process parameters may include, but are not limited to, the following: the back-to-back drive process, the black start process, and the line charging process are all not running; or any one of the back-to-back drive process, the black start process, and the line charging process is running.

[0036] The unit operating speed is used to characterize the current operating speed of the unit. Optionally, the unit operating speed can be obtained through sensing devices. In one embodiment, the unit operating speed can be the speed of the unit's generator.

[0037] Switch closure state parameters are parameters used to characterize the current closed state of the switch. Optionally, switch closure state parameters may include, but are not limited to, open state, closed state, etc.

[0038] In one embodiment, each power device in the corresponding unit is equipped with a sensor to detect the status parameters of each power device. The sensor is connected to the control mechanism to transmit the detected status parameters of each power device to the control mechanism so that the control mechanism can control each power device according to the status parameters transmitted by the sensor.

[0039] In one optional embodiment, there are multiple generating units, each with its own corresponding unit number. Each electrical device within a unit is further numbered based on its unit number, allowing for identification based on both the unit number and the device number. Optionally, the sensing device can number the detected electrical devices. When transmitting the detected status parameters of an electrical device to the control device, the sensing device uses the device number to number the detected status parameters. This allows the control mechanism to store the received status parameters based on the device number, enabling subsequent retrieval of the device's parameters. Alternatively, the status parameters of each electrical device within the mechanism can be obtained based on the mechanism number.

[0040] Step 204: Determine the current operating status of the unit to be processed based on the unit control status parameters, the unit outlet circuit breaker status parameters, the operating process parameters, the unit operating speed, and the switch closing status parameters.

[0041] The current operating status is used to characterize the current operating condition of the unit to be processed. Optionally, the current operating status may include, but is not limited to, normal operating status, forced tripping status, etc.

[0042] Optionally, preset status parameters can be set for each power device, and the current operating status of the unit to be processed can be determined by comparing the status parameters of each power device with the corresponding preset status parameters.

[0043] In an optional embodiment, the corresponding preset parameters are obtained according to the unit number. The preset conditions include preset unit control status parameters, preset unit outlet circuit breaker status parameters, preset operating condition process parameters, preset unit operating speed, and preset switch closing status 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 drive process, black start process, and line charging process are not running; the preset unit operating speed is used to determine the unit's operating speed; and the preset switch closing state parameters are used to characterize that the switch is in the open state. Optionally, the preset unit operating speed can be greater than or equal to 101% or less than or equal to 99%. Optionally, corresponding to the preset unit control state parameters, the unit is in normal operation at this time and is not in the black start steady state.

[0045] Optionally, the status parameters of each power device are compared one by one with the corresponding preset status parameters to obtain the comparison results of the status parameters of each power device with their respective preset status parameters. Optionally, the matching results are based on the first matching result of the unit control status parameters and the preset unit control status parameters, the second matching result of the unit outlet circuit breaker status parameters and the preset unit circuit breaker status parameters, the third matching result of the unit transformer parameters and the preset unit transformer parameters, the fourth matching result of the unit operating speed and the preset unit operating speed, and the fifth matching result of the switch closing status parameters and the preset switch closing status parameters.

[0046] In one embodiment, the current operating state of the unit to be processed is determined based on the matching result between the state parameters of each power device and the preset state parameters corresponding to each power device. Optionally, when the unit control state parameters match the preset unit control state parameters, the unit circuit breaker state parameters match the preset unit circuit breaker state parameters, the unit transformer parameters match the preset unit transformer parameters, the unit operating speed matches the preset unit operating speed, and the switch closing state parameters match the preset switch closing state parameters, the current operating state of the unit to be processed is determined to be an operating state requiring forced tripping.

[0047] In an optional embodiment, to improve practicality, multiple switching lines can be provided for the unit when transmitting electrical energy from the unit to the outside. For example, for unit 1, switching line 1 and switching line 2 can be provided. Optionally, the switching lines can include at least one switch. For example, switching line 1 includes switch YACL10 GS101 (5002), while switching line 2 can include three switches YACL10 GS101 (5001), YACL10 GS101 (5003), and YACL10GS101 (5004).

[0048] Optionally, for switch line 1, when switch YACL10 GS101(5002) is closed, unit 1 can transmit power externally; for switch line 2, YACL10 GS101(5001), YACL10 GS101(5003) and YACL10 GS101(5004) must all be closed in order to transmit power externally.

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

[0050] In an alternative embodiment, multiple units may use the same power transmission switching line. For example, when unit 1 and unit 2 transmit power, they both use line 1 and line 2.

[0051] Alternatively, different units can use different external power supply switch lines. For example, units 1 and 2 use line 1 and line 2, while units 3 and 4 use line 3 and line 4.

[0052] In one embodiment, when any one of the following does not match: a first matching result of the unit control status parameters with preset unit control status parameters, a second matching result of the unit outlet circuit breaker status parameters with preset unit outlet circuit breaker status parameters, a third matching result of the operating process parameters with preset operating process parameters, a fourth matching result of the unit operating speed with preset unit operating speed, or a fifth matching result of the switch closing status parameters with preset switch closing status parameters, the current operating state of the unit to be processed is determined to be 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 results do not match can be obtained, an alarm signal can be generated based on the power equipment, and the alarm signal can be transmitted to the terminal equipment corresponding to the safety officer for the safety officer to investigate.

[0053] In one embodiment, if none of the following matches are found: the first matching result of the unit control status parameters with the preset unit control status parameters; the second matching result of the unit outlet circuit breaker status parameters with the preset unit outlet circuit breaker status parameters; the third matching result of the operating process parameters with the preset operating process parameters; the fourth matching result of the unit operating speed with the preset unit operating speed; and the fifth matching result of the switch closing status parameters with the preset switch closing status parameters, then the unit to be processed can be considered to be in normal operating condition and no processing is required.

[0054] Step 206: When the current operating state of the unit to be processed is the preset state, control the unit to be processed to trip by force.

[0055] In an optional embodiment, a control signal can be set according to the current operating state of the unit. For example, when the current operating state requires forced tripping, 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, the 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 that requires forced tripping, a forced tripping control command is generated; the forced tripping control command is used to control the forced tripping of the unit to be processed.

[0058] Among them, the forced trip control command controls the unit to be processed to trip.

[0059] Optionally, when it is determined that the unit needs to be forcibly tripped, a forced trip command can be generated, and the unit can be controlled according to the forced trip command.

[0060] In one embodiment, a forced trip switch can be installed for the generating unit to achieve forced tripping. Optionally, when the forced trip switch is open, it indicates that the generating unit has been forcibly tripped. Optionally, the forced trip switch can be a 500kV switch.

[0061] In an optional embodiment, controlling the unit to be processed to trip according to the forced trip control command includes: determining the number of the corresponding forced trip switch according to the unit number; and controlling the forced trip switch corresponding to the number of the forced trip switch to trip according to the forced trip command.

[0062] Optionally, the intelligent switch includes a forced trip switch, which is used to achieve forced tripping of the unit. Optionally, each electrical device in the unit has its own forced trip switch, or a single forced trip switch can be set for the entire unit to achieve forced tripping control of the entire unit.

[0063] In one embodiment, when the current operating state of the unit is one requiring forced tripping, it indicates that a forced trip of the unit is necessary. Optionally, the forced trip switch corresponding to the unit is obtained based on the unit number, and the forced trip switch is controlled to achieve forced tripping of the unit. Optionally, controlling the operation of the forced trip switch can be done by disconnecting the forced trip switch. A forced trip switch is set on the unit bus, and when the forced trip switch is in the open state, it indicates that the unit has been forcibly disconnected.

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

[0065] In one embodiment, a forced trip command is used to control the corresponding forced trip switch of the unit to open, thereby achieving forced tripping of the unit.

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

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

[0068] In one embodiment, when there are at least three units, a linkage mechanism can be set between each unit. However, if multiple units have been forcibly tripped, the unit currently to be processed will also be forcibly tripped.

[0069] Optionally, on the server side, a detection thread can be set up for each unit to detect whether the current unit has received forced trip information from other units, and the number of times it has received forced trip information from other units.

[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 besides that unit.

[0071] In one embodiment, when the server sends the forced trip information corresponding to the unit, it counts the number of times the information is sent to the unit. When the count is greater than or equal to a preset number, a forced trip command is generated for the unit, and the unit is forced to trip according to the forced trip command.

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

[0073] Optionally, when the number of trips exceeds the preset number, the control mechanism on the unit side can generate a forced trip command, and control the unit to trip in a forced manner according to the forced trip command.

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

[0075] In the aforementioned unit control method, when implementing unit control, the current operating status of the unit is determined based on the unit control status parameters in the unit circuit, the status parameters of the unit's output circuit breaker, the operating process parameters, the unit's operating speed, and the switch and status parameters. Control of the unit is then implemented based on this current operating status. Utilizing multiple parameters to control the unit effectively ensures the accuracy of unit control, thereby ensuring accurate and timely tripping of the unit in the event of disconnection or other situations, effectively guaranteeing the unit's safety.

[0076] In one exemplary embodiment, such as Figure 3 As shown, a unit control method is provided, which is applied to... Figure 1 Taking the server in the example, the explanation includes the following steps 302 to 310. Wherein:

[0077] Step 302: Obtain the unit number of the unit to be processed, and obtain the unit control status parameters, unit outlet circuit breaker status parameters, operating process parameters, unit operating speed and switch closing status parameters in the unit circuit corresponding to the unit number.

[0078] Step 304: Obtain the corresponding preset unit control status parameters, preset unit circuit breaker status parameters, preset unit transformer parameters, preset unit operating speed, and preset switch closing status parameters according to the unit number.

[0079] Among them, the preset unit control status parameters are used to characterize the normal operation of the unit, the preset unit outlet circuit breaker status 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 drive process, black start process and line charging process are not running, the preset unit operating speed is used to determine the speed of the unit operation, and the preset switch closing status parameters are used to characterize that the prime number switch is in the open state.

[0080] Step 306: Determine whether the unit control status parameters match the preset unit control status parameters, whether the unit outlet circuit breaker status parameters match the preset unit outlet circuit breaker status parameters, whether the operating condition flow parameters match the preset operating condition flow parameters, whether the unit operating speed matches the preset unit operating speed, and whether the switch closing status parameters match the preset switch closing status parameters. If yes, proceed to step 308; otherwise, proceed to step 318.

[0081] Step 308: Determine that the current operating status of the unit to be processed is an operating status that requires forced tripping.

[0082] Step 310: Determine whether the current operating status of the unit to be processed is an operating status that requires forced tripping. If yes, proceed to step 312; otherwise, proceed to step 318.

[0083] Step 312: Generate a forced trip control command.

[0084] Among them, the forced trip control command is used to control the unit to be processed to trip.

[0085] Step 314: Determine the corresponding forced trip switch number based on the unit number.

[0086] Step 316: Control the forced trip switch corresponding to the number of the forced trip switch to trip according to the forced trip command.

[0087] Step 318: Check whether information from other units indicating that they have been forcibly tripped has been received. If yes, proceed to step 320; otherwise, proceed to step 324.

[0088] Step 320: Determine the number of times the information of forced tripping corresponding to other units is received from other units.

[0089] Step 322: Determine whether the number of times the information of forced tripping corresponding to other units transmitted by other units is greater than or equal to the preset number. If yes, proceed to step 312; otherwise, proceed to step 324.

[0090] Step 324: Obtain the unit number of other units to be processed, and continue to step 302.

[0091] In this embodiment, when implementing unit control, the current operating status of the unit is determined based on the unit control status parameters in the unit circuit, the status parameters of the unit's output circuit breaker, the operating process parameters, the unit's operating speed, and the switch and status parameters. Control of the unit is then implemented based on this current operating status. Utilizing multiple parameters to control the unit effectively ensures the accuracy of unit control, thus ensuring accurate and timely tripping of the unit in the event of disconnection or other situations, effectively guaranteeing the unit's safety.

[0092] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
