[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] The tripping control method of the generator set provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown in the figure, the generator set includes a main processor 101 and a standby processor 102. The main processor and the standby processor 102 are connected to each other.

[0051] When the main processor 101 fails, the standby processor 102 can first obtain at least one type of trip signal of the generator set from the main processor 101, and obtain the unit speed of the generator set and the circuit breaker disconnection condition of the generator set. Secondly, the standby processor 102 can disconnect the outlet switch of the generator set according to the type of the trip signal obtained, the unit speed and the circuit breaker disconnection condition. Thirdly, the standby processor 102 can determine the target control component from the multiple shutdown control components of the generator set according to the type of the trip signal obtained and generate a shutdown control instruction corresponding to the target control component, and the shutdown control instruction is used to instruct the target control component to perform a shutdown operation. Finally, the standby processor 102 can send a shutdown control instruction to the target control component.

[0052] It should be understood that the embodiments of the present application do not limit the types of the main processor 101 and the backup processor 102. In some embodiments, the main processor and the backup processor may be a programmable logic controller (PLC) on a generator set.

[0053] In an exemplary embodiment, Figure 2 As shown, a tripping control method for a generator set is provided, and the method is applied to Figure 1 The following is an example of the backup processor of the generator set in FIG. 1 , including S201-S205:

[0054] S201. Obtain at least one type of trip signal of a generator set from a main process of the generator set.

[0055] In the present application, when the main processor of the generator fails, the backup processor can obtain at least one type of trip signal of the generator set from the main processor of the generator set.

[0056] The trip signal may include a quick shutdown (QSD) type trip signal and an emergency shutdown (ESD) type trip signal.

[0057] Exemplarily, the triggering conditions of the QSD type tripping signal include abnormal current or voltage of the generator set, such as a tripping signal triggered by a short circuit, overload, etc.

[0058] Exemplarily, the triggering condition of the ESD type trip signal includes receiving an external safety risk alarm signal, for example, a trip signal triggered by an external safety risk alarm signal such as fire or gas leakage.

[0059] It should be understood that since an ESD type trip signal is generally required to handle an emergency dangerous situation, the response speed of a QSD type trip signal is slower than that of an ESD type trip signal.

[0060] It should be noted that the backup processor may only obtain a QSD type trip signal, or only obtain an ESD type trip signal, or obtain both a QSD type trip signal and an ESD type trip signal at the same time, or obtain both a QSD type trip signal and an ESD type trip signal in sequence, and the embodiments of the present application do not impose any restrictions on this.

[0061] In some embodiments, the main processor and the backup processor can obtain at least one type of trip signal from each other. The QSD type and ESD type trip signals generated by the backup processor can be sent to the main processor through communication and hard wiring. The QSD type and ESD type trip signals generated by the main processor are also sent to the backup PLC through communication and hard wiring.

[0062] In some embodiments, both the main processor and the standby processor can generate a watchdog fault signal. When the main processor fails, the watchdog fault signal of the main processor can be sent to the standby processor, so that the standby processor can perform the tripping control of the generator set. When the standby processor fails, the watchdog fault signal of the standby processor can be sent to the main processor, so that the main processor can perform the tripping control of the generator set.

[0063] S202: Obtain the unit speed of the generator set and the circuit breaker disconnection condition of the generator set.

[0064] In this step, after the backup processor of the generator set obtains at least one type of trip signal of the generator set from the main processor of the generator set, the generator set speed and the circuit breaker disconnection condition of the generator set can be obtained.

[0065] It should be understood that the embodiments of the present application do not limit how to obtain the unit speed of the generator set. In some embodiments, the generator set is provided with a unit speed measuring device, and the backup processor determines the unit speed of the generator set by reading the counting pulses in the unit speed measuring device.

[0066] It should be understood that the embodiments of the present application do not limit the conditions for disconnecting the circuit breaker of the generator set. In some embodiments, the condition for disconnecting the circuit breaker of the generator set may be that the actual active power value of the generator set allows the circuit breaker to be disconnected.

[0067] S203: Disconnect the outlet switch of the generator set according to the type of the acquired trip signal, the unit speed and the circuit breaker disconnection condition.

[0068] In this step, after the standby processor obtains the unit speed and the circuit breaker disconnection condition, the outlet switch of the generator set can be disconnected according to the type of the obtained trip signal, the unit speed and the circuit breaker disconnection condition.

[0069] In some embodiments, if a QSD type trip signal is obtained, the circuit breaker disconnection condition information is met, and the unit speed is greater than or equal to the speed threshold, the outlet switch of the generator set is disconnected.

[0070] Among them, the speed threshold can be set according to actual conditions, such as 90%, 80%, etc.

[0071] Exemplarily, when a QSD type trip signal appears, the outlet switch of the generator set may be disconnected when the actual active power value of the generator set allows disconnection of the circuit breaker and the speed of the generator set is ≥90%.

[0072] In some embodiments, if a QSD type trip signal is obtained, the delay time of the QSD type trip signal exceeds a preset time length, and the unit speed is greater than or equal to a speed threshold, the outlet switch of the generator set is disconnected.

[0073] Among them, whether the delay time of the QSD type trip signal exceeds the preset time can be determined by a timer, and the timer is reset when the actual value of the active power of the generator group allows the circuit breaker to be disconnected. The preset time can be specific according to the actual situation, and the embodiment of the present application does not limit this.

[0074] For example, if a QSD type trip signal is delayed for a preset period of time after being actuated, a command may be issued to disconnect the generator set's export switch when the unit speed is ≥90%.

[0075] In some embodiments, if an ESD type trip signal is obtained and the unit speed is greater than or equal to a speed threshold, the outlet switch of the generator set is disconnected.

[0076] Exemplarily, when an ESD type trip signal appears and the unit speed is ≥90%, the outlet switch of the generator set is immediately disconnected.

[0077] Exemplarily, after a QSD type trip signal appears, if the circuit breaker disconnected position signal is not received within a certain period of time, an ESD type trip signal is triggered. When the backup processor obtains the ESD type trip signal, the generator set's outlet switch is disconnected when the unit speed is ≥90%.

[0078] In other embodiments, if the outlet switch of the generator set is disconnected and a QSD type trip signal is obtained, the operation of the excitation component of the generator set is stopped after the generator set is shut down. If the outlet switch of the generator set is disconnected and an ESD type trip signal is obtained, the operation of the excitation component of the generator set is cut off during the operation of the generator set.

[0079] Exemplarily, when a QSD type trip signal appears, after the outlet switch of the generator set has been disconnected, a command is issued to stop the excitation of the excitation component. When an ESD type trip signal appears, after the outlet switch of the generator set has been disconnected, a command is immediately issued to trip the excitation, that is, to cut off the operation of the excitation component of the generator set during the operation of the generator set.

[0080] It should be understood that the embodiments of the present application do not limit how to verify that the outlet switch of the generator set is disconnected. In some embodiments, the backup server can determine that the outlet switch of the generator set is disconnected when any of the following conditions are met. The conditions include: receiving feedback information that the circuit breaker outlet switch is disconnected from the main processor through communication and the communication between the main processor and the backup processor is normal; receiving feedback information that the circuit breaker outlet switch is disconnected from the main processor through hard wiring and the communication between the main processor and the backup processor fails.

[0081] S204. According to the type of the acquired trip signal, determine a target control component from multiple shutdown control components of the generator set and generate a shutdown control instruction corresponding to the target control component, wherein the shutdown control instruction is used to instruct the target control component to perform a shutdown operation.

[0082] In this step, after the standby processor obtains at least one type of trip signal, it can also determine the target control component from multiple shutdown control components of the generator set according to the type of the obtained trip signal and generate a shutdown control instruction corresponding to the target control component.

[0083] In some embodiments, if a QSD type trip signal or an ESD type trip signal is obtained, it is determined that the components to be controlled in the generator set include an emergency shutdown solenoid valve and a main water inlet valve in the generator set. Subsequently, the standby processor can generate a first shutdown control instruction corresponding to the emergency shutdown solenoid valve and a second shutdown control instruction corresponding to the main water inlet valve, the first shutdown control instruction is used to instruct the emergency shutdown solenoid valve to perform an emergency shutdown operation, and the second shutdown control instruction is used to instruct the main water inlet valve to close.

[0084] For example, when a QSD type trip signal or an ESD type trip signal appears, the standby processor may determine that the emergency shutdown solenoid valve is a component to be controlled. Subsequently, the standby processor may immediately generate a first shutdown control instruction to instruct the emergency shutdown solenoid valve to close to complete the emergency shutdown operation, and the emergency shutdown solenoid valve is on the speed governor of the generator set.

[0085] For example, when a QSD type trip signal or an ESD type trip signal appears, the standby processor may determine that the main water inlet valve is a component to be controlled. Subsequently, the standby processor may be a component to be controlled. Subsequently, the standby processor may issue a second shutdown control instruction to instruct the main water inlet valve to close.

[0086] In other embodiments, if a QSD type trip signal is obtained, the standby processor may also send an excitation adjustment instruction to the excitation component in the generator set, and the excitation adjustment instruction is used to reduce the excitation current of the generator set. Subsequently, the standby processor may obtain the reactive power of the generator set. If the absolute value of the reactive power of the generator set is less than the reactive power threshold, the standby processor may send a reset instruction to the excitation component.

[0087] Exemplarily, when a QSD type trip signal appears, the standby processor may also immediately send an excitation adjustment instruction to the excitation component, so that the excitation component reduces the excitation current of the generator set to reactive power. Subsequently, the standby processor may obtain the reactive power of the generator set, and when the absolute value of the reactive power of the generator set is less than the reactive power threshold, the excitation component may be reset by sending a reset instruction.

[0088] Among them, the reactive power threshold can be specifically set according to actual conditions, and the embodiments of the present application do not limit this.

[0089] In some embodiments, the backup processor may also trip the protection mode of the relay protection device of the generator set based on the type of the acquired trip signal.

[0090] Exemplarily, when a QSD type trip signal appears and an ESD type trip signal does not appear, the backup processor immediately issues an instruction to the relay protection device, thereby setting the protection mode of the relay protection device to the QSD mode. When an ESD type trip signal appears, an instruction is immediately issued to the relay protection device, thereby setting the protection mode of the relay protection device to the ESD mode.

[0091] It should be understood that in the present application, the backup processor does not have electrical brake and mechanical brake activation and deactivation control.

[0092] S205: Send a shutdown control instruction to the target control component.

[0093] The trip control method of the generator set provided by the embodiment of the present application first obtains at least one type of trip signal of the generator set from the main processing of the generator set, and obtains the unit speed of the generator set and the disconnection condition of the circuit breaker of the generator set. Secondly, according to the type of the trip signal obtained, the unit speed and the disconnection condition of the circuit breaker, the outlet switch of the generator set is disconnected. Thirdly, according to the type of the trip signal obtained, the target control component is determined from the multiple shutdown control components of the generator set and a shutdown control instruction corresponding to the target control component is generated, and the shutdown control instruction is used to instruct the target control component to perform a shutdown operation. Finally, the shutdown control instruction is sent to the target control component. Since at least one type of trip signal is obtained from the main processing of the generator set by the backup processor of the generator set, and then the backup processor disconnects the outlet switch of the generator set based on the type of the trip signal obtained, and the shutdown control instructions of the multiple shutdown control components of the generator set are generated and sent, so that when the main processor fails, the generator set can also be guaranteed to be safely shut down, thereby improving the operating safety of the generator set.

[0094] The following describes how to determine a target control component from multiple shutdown control components of a generator set and generate a shutdown control instruction corresponding to the target control component. Figure 3 A flow chart of another method for controlling the tripping of a generator set provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the tripping control method of the generator set includes S301-S305:

[0095] S301. Obtain at least one type of trip signal of a generator set from a main process of the generator set.

[0096] S302: Obtain the unit speed of the generator set and the circuit breaker disconnection condition of the generator set.

[0097] S303: Disconnect the outlet switch of the generator set according to the type of the acquired trip signal, the unit speed and the circuit breaker disconnection condition.

[0098] S304: If a QSD type trip signal or an ESD type trip signal is obtained, it is determined that the components to be controlled in the generator set include an emergency shutdown solenoid valve and a main water inlet valve in the generator set.

[0099] S305, generating a first shutdown control instruction corresponding to the emergency shutdown solenoid valve and a second shutdown control instruction corresponding to the main water inlet valve, the first shutdown control instruction is used to instruct the emergency shutdown solenoid valve to perform an emergency shutdown operation, and the second shutdown control instruction is used to instruct the main water inlet valve to close.

[0100] The following describes how to trip the excitation current. Figure 4 A flow chart of another method for controlling the tripping of a generator set provided in an embodiment of the present application is shown as follows: Figure 4 As shown, the tripping control method of the generator set includes S401-S408:

[0101] S401. Obtain at least one type of trip signal of a generator set from a main process of the generator set.

[0102] S402: Obtain the unit speed of the generator set and the circuit breaker disconnection condition of the generator set.

[0103] S403: Disconnect the outlet switch of the generator set according to the type of the acquired trip signal, the unit speed and the circuit breaker disconnection condition.

[0104] S404. According to the type of the acquired trip signal, determine a target control component from multiple shutdown control components of the generator set and generate a shutdown control instruction corresponding to the target control component, where the shutdown control instruction is used to instruct the target control component to perform a shutdown operation.

[0105] S405: Send a shutdown control instruction to the target control component.

[0106] S406: If a QSD type trip signal is obtained, an excitation adjustment instruction is sent to an excitation component in the generator set, where the excitation adjustment instruction is used to reduce the excitation current of the generator set.

[0107] S407: Obtain reactive power of the generator set.

[0108] S408: If the absolute value of the reactive power of the generator set is less than the reactive power threshold, a reset instruction is sent to the excitation component.

[0109] The trip control method of the generator set provided by the embodiment of the present application first obtains at least one type of trip signal of the generator set from the main processing of the generator set, and obtains the unit speed of the generator set and the disconnection condition of the circuit breaker of the generator set. Secondly, according to the type of the trip signal obtained, the unit speed and the disconnection condition of the circuit breaker, the outlet switch of the generator set is disconnected. Thirdly, according to the type of the trip signal obtained, the target control component is determined from the multiple shutdown control components of the generator set and a shutdown control instruction corresponding to the target control component is generated, and the shutdown control instruction is used to instruct the target control component to perform a shutdown operation. Finally, the shutdown control instruction is sent to the target control component. Since at least one type of trip signal is obtained from the main processing of the generator set by the backup processor of the generator set, and then the backup processor disconnects the outlet switch of the generator set based on the type of the trip signal obtained, and the shutdown control instructions of the multiple shutdown control components of the generator set are generated and sent, so that when the main processor fails, the generator set can also be guaranteed to be safely shut down, thereby improving the operating safety of the generator set.

[0110] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0111] Based on the same inventive concept, the embodiment of the present application also provides a trip control device for a generator set for implementing the trip control method of the generator set involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of the trip control device for one or more generator sets provided below can refer to the limitations of the trip control method for the generator set above, and will not be repeated here.

[0112] In an exemplary embodiment, Figure 5 As shown, a trip control device 500 of a generator set is provided, which is applied to a backup processor of the generator set, including: an acquisition module 501, a disconnection module 502 and an instruction sending module 503, wherein:

[0113] The acquisition module 501 is used to acquire at least one type of trip signal of the generator set from the main processing of the generator set, and different types of trip signals have different triggering conditions and response speeds; and acquire the generator set speed and the breaker disconnection condition of the generator set.

[0114] The disconnection module 502 is used to disconnect the output switch of the generator set according to the type of the trip signal, the unit speed information and the circuit breaker disconnection condition information obtained.

[0116] In one of the embodiments, the types of trip signals include quick power shutdown (QSD) type trip signals and emergency power shutdown (ESD) type trip signals.
