[0034] This embodiment provides a test method for a generator set controller that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0035] Figure 2 This is a flowchart of a test method for a generator set controller according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:

[0036] Step S201: Receive control signals from the generator set controller. The control signals include a start signal, a stop signal, a closing signal, and a opening signal. The start signal is a signal to control the three-phase power supply to start. The stop signal is a signal to control the three-phase power supply to stop. The closing signal is a signal to control the connection of the transmission line between the three-phase power supply and the generator set controller. The opening signal is a signal to control the disconnection of the transmission line between the three-phase power supply and the generator set controller. The three-phase power supply is used to simulate the generator set outputting a power generation signal. The power generation signal is any one or more of a voltage signal, a frequency signal, and a phase signal.

[0037] Specifically, the functions of the generator set controller include controlling the start and stop of the generator set, as well as controlling the generator set to connect to and disconnect from the power transmission circuit. These functions are achieved by issuing corresponding control signals, namely start signal, stop signal, closing signal, and opening signal. The generator set outputs a power generation signal through a three-phase power supply to simulate the generator set output, thereby testing the functions of the generator set controller.

[0038] Step S202: In response to the control signal, the analog device is controlled to output an analog signal. The analog device includes at least the three-phase power supply. The analog signal is a feedback signal generated in response to the control signal.

[0039] Specifically, in response to the above control signal, the analog device outputs an analog signal. For example, the three-phase power supply outputs a power generation signal in response to the start signal, or the three-phase power supply stops outputting a power generation signal in response to the stop signal. In step S203, it is determined whether the generator set controller is faulty based on the above control signal and the above analog signal.

[0040] Specifically, after the generator set controller sends a control signal, it can determine whether the function corresponding to the control signal of the generator set controller is normal by whether the analog device responds to the control signal and feeds back the corresponding analog signal. After testing all functions, it can be determined whether the generator set controller is faulty and the corresponding fault type.

[0041] In the aforementioned test method for the generator set controller, firstly, control signals from the generator set controller are received. These control signals include a start signal, a stop signal, a closing signal, and a opening signal. The start signal controls the start of the three-phase power supply, the stop signal controls the stop of the three-phase power supply, the closing signal controls the connection of the transmission line between the three-phase power supply and the generator set controller, and the opening signal controls the disconnection of the transmission line between the three-phase power supply and the generator set controller. The three-phase power supply is used to simulate the generator set outputting a power generation signal, which is any one or more of a voltage signal, a frequency signal, and a phase signal. Then, in response to the control signals, a simulation device is controlled to output a simulation signal. The simulation device includes at least the three-phase power supply, and the simulation signal is a feedback signal generated in response to the control signals. Finally, based on the control signals and the simulation signals, it is determined whether the generator set controller is faulty. This method uses the control signal issued by the generator set controller to cause the analog device to respond to the control signal and output a corresponding analog signal, thus simulating the control process of the generator set controller. Based on the control signal and the analog signal, it can determine whether the generator set controller is faulty, thereby realizing the functional test of the generator set controller and solving the problem of difficulty in testing the function of the generator set controller in the prior art.

[0042] To test the functions corresponding to the generator set controller's closing and opening signals, in an optional embodiment, the simulation device further includes an ATS simulation module. This ATS simulation module simulates power switching via an ATS system. The simulated signals include the generator signal, the conduction feedback signal, and the disconnection feedback signal. Step S202 includes:

[0043] Step S2021: In response to the above-mentioned start signal, control the above-mentioned three-phase power supply to output the above-mentioned power generation signal, and in response to the above-mentioned closing signal, control the above-mentioned ATS analog module to conduct the transmission lines of the above-mentioned three-phase power supply and the above-mentioned generator set controller and output the above-mentioned conduction feedback signal.

[0044] In step S2022, in response to the shutdown signal, the three-phase power supply is controlled to stop outputting the power generation signal, and in response to the trip signal, the ATS analog module is controlled to disconnect the transmission lines of the three-phase power supply and the generator set controller and output the disconnection feedback signal.

[0045] Specifically, the ATS simulation module is used to simulate ATS power switching, controlling the connection and disconnection of the transmission line between the three-phase power supply and the generator controller. When the user operates the switch, triggering the starting conditions, the generator controller sends a start signal. In response to this start signal, the generator controller controls the three-phase power supply to output the generated signal. After the three-phase power supply starts without fault, the generator controller sends a closing signal, controlling the ATS simulation module to connect the transmission line between the three-phase power supply and the generator controller, and outputs the connection feedback signal to indicate successful connection. The generator controller then receives the generated signal from the three-phase power supply and can test the power generation. To test whether the generator set controller can properly control the generator set's start-up and circuit breaker closing functions, similarly, when the user operates the switch to trigger the shutdown condition, the generator set controller can send a trip signal to control the ATS simulation module to disconnect the three-phase power supply and the generator set controller's transmission lines, and output the disconnection feedback signal to indicate that the tripping was successful. The generator set controller will no longer receive the three-phase power supply's output power signal. Upon receiving the disconnection feedback signal, the generator set controller can send a shutdown signal. In response to the shutdown signal, the three-phase power supply will stop outputting the power signal, thus testing whether the generator set controller can properly control the generator set's shutdown and circuit breaker closing functions.

[0046] To determine whether the generator set startup function is normal, in one optional embodiment, after controlling the three-phase power supply to output the generation signal in response to the startup signal, and controlling the ATS analog module to connect the transmission lines of the three-phase power supply and the generator set controller and output the connection feedback signal in response to the closing signal, step S203 includes:

[0047] Step S2031: If the above-mentioned analog device does not receive the above-mentioned start signal and / or the above-mentioned generator set controller does not receive the above-mentioned power generation signal, it is determined that the function of the above-mentioned generator set controller in controlling the generator set start is faulty.

[0048] Step S2032: When the above-mentioned analog device receives the above-mentioned start signal and the above-mentioned generator set controller receives the above-mentioned power generation signal, it is determined that the function of the above-mentioned generator set controller in controlling the generator set start is fault-free.

[0049] Specifically, if the aforementioned analog device does not receive the aforementioned start signal, it indicates that the generator set controller cannot send the start signal normally, and the start control function is faulty. If the aforementioned analog device receives the aforementioned start signal, but the aforementioned generator set controller does not receive the aforementioned power generation signal, then the closing function of the transmission line connecting the aforementioned three-phase power supply and the aforementioned generator set controller is faulty. Only when the aforementioned analog device receives the aforementioned start signal and the aforementioned generator set controller receives the aforementioned power generation signal, it indicates that the generator set starts normally and outputs a power generation signal to the generator set controller, that is, both the start control function and the closing control function are fault-free.

[0050] To test the function of the generator set controller in balancing the output power of the parallel generator sets, in an optional embodiment, after controlling the three-phase power supply to stop outputting the generation signal in response to the shutdown signal, and controlling the ATS simulation module to disconnect the transmission lines of the three-phase power supply and the generator set controller and output the disconnection feedback signal in response to the trip signal, step S203 further includes:

[0051] Step S2033: If the above-mentioned analog device does not receive the above-mentioned shutdown signal and / or the above-mentioned generator set controller receives the above-mentioned power generation signal, it is determined that the function of the above-mentioned generator set controller in controlling the shutdown of the generator set has failed.

[0052] Step S2034: If the above-mentioned analog device receives the above-mentioned shutdown signal and the above-mentioned generator set controller does not receive the above-mentioned analog signal, it is determined that the function of the above-mentioned generator set controller in controlling the shutdown of the generator set is fault-free.

[0053] Specifically, if the aforementioned analog device does not receive the aforementioned shutdown signal, it indicates that the generator set controller cannot normally issue a shutdown signal, and the shutdown control function is faulty. If the aforementioned analog device receives the aforementioned shutdown signal and the aforementioned generator set controller receives the aforementioned power generation signal, then the tripping function of disconnecting the aforementioned three-phase power supply and the transmission line of the aforementioned generator set controller is faulty. Only if the aforementioned analog device receives the aforementioned shutdown signal and the aforementioned generator set controller does not receive the aforementioned analog signal, it indicates that the output power generation signal cannot be sent to the generator set controller and the generator set shuts down normally, that is, both the shutdown control function and the tripping control function are fault-free.

[0054] To test the generator set alarm function, in an optional implementation, after controlling the ATS simulation module to connect the three-phase power supply and the generator set controller's transmission lines and output the connection feedback signal, step S203 further includes:

[0055] Step S2035: If the generator set controller does not receive the conduction feedback signal and does not issue the first alarm signal, it is determined that the alarm function of the generator set controller has malfunctioned.

[0056] After controlling the ATS simulation module to disconnect the three-phase power supply and the generator set controller's transmission lines and output the disconnection feedback signal, step S203 further includes:

[0057] Step S2036: If the generator set controller does not receive the disconnection feedback signal and does not issue a second alarm signal, it is determined that the alarm function of the generator set controller has malfunctioned.

[0058] Specifically, if the generator set controller does not receive the aforementioned conduction feedback signal or the aforementioned disconnection feedback signal, it will issue a corresponding alarm signal. If no alarm signal is issued, it indicates that the alarm function is faulty. Of course, this is not limited to the absence of feedback; other faults can also issue corresponding alarm signals to remind personnel to perform maintenance.

[0059] To test the function of the generator set controller in balancing the output power of parallel generator sets, in one optional embodiment, the three-phase power supply includes a first three-phase power supply and a second three-phase power supply, the generator set controller includes a first generator set controller and a second generator set controller, the ATS simulation module includes a first ATS simulation module and a second ATS simulation module, and step S202 includes:

[0060] Step S2023: In response to the first start signal output by the first generator set controller, control the first three-phase power supply to output a first power generation signal, and in response to the first closing signal output by the first generator set controller, control the first ATS analog module to conduct the transmission lines of the first three-phase power supply and the first generator set controller and output a first conduction feedback signal.

[0061] In step S2024, in response to the second start signal output by the second generator set controller, the second three-phase power supply is controlled to output a second power generation signal, and in response to the second closing signal output by the second generator set controller, the second ATS analog module is controlled to conduct the transmission lines of the second three-phase power supply and the second generator set controller and output a second conduction feedback signal.

[0062] Specifically, there can be multiple generator sets. After the single-unit mode function test of a single generator set is completed, it is also necessary to test the dual-unit parallel function test of two generator sets connected in parallel. The first three-phase power supply and the second three-phase power supply are started and connected in parallel respectively. Based on whether the output power of the first three-phase power supply and the second three-phase power supply are the same, the function of the generator set controller to balance the output power of the parallel generator sets can be tested.

[0063] To test the function of the generator set controller in balancing the output power of the parallel generator sets, in an optional embodiment, after controlling the second three-phase power supply to output a second generation signal in response to the second start signal output by the second generator set controller, and controlling the second ATS simulation module to conduct the transmission lines of the second three-phase power supply and the second generator set controller and output a second conduction feedback signal in response to the second closing signal output by the second generator set controller, step S203 further includes:

[0064] Step S2037: If the first generator controller does not receive the first feedback signal from the second generator controller, it is determined that the communication function of the first generator controller is faulty, and / or, if the second generator controller does not receive the second feedback signal from the first generator controller, it is determined that the communication function of the second generator controller is faulty. The first feedback signal is the first power generation signal forwarded by the first generator controller to the second generator controller, and the second feedback signal is the second power generation signal forwarded by the second generator controller to the first generator controller.

[0065] Step S2038: If the first power generation signal and the second power generation signal are different, it is determined that the synchronization function of the first generator set controller and the second generator set controller has failed.

[0066] Step S2039: If the output power of the first three-phase power supply and the output power of the second three-phase power supply are different, determine that the first generator set controller or the second generator set controller has a reverse power fault.

[0067] Specifically, the first generator set controller and the second generator set controller are communicatively connected to determine whether the generation signals of the two parallel three-phase power supplies are consistent. If the feedback signal between the first and second generator set controllers cannot be received, it indicates a communication function failure. If the communication function is not faulty, but the first and second generation signals are different, it indicates a synchronization function failure between the first and second generator set controllers. Furthermore, if the settings of the first and second three-phase power supplies are different during synchronization, the setting knob can be manually adjusted to make them the same, simulating speed regulation. Additionally, if the output power of the first and second three-phase power supplies is different, a reverse power fault occurs.

[0068] To test for other functional failures, in one optional embodiment, the simulation device further includes a signal simulator, which is used to simulate the sensors of the generator set generating corresponding detection signals. After determining whether the generator set controller is faulty based on the control signal and the simulated signal, the method further includes:

[0069] Step S301: If the generator set controller does not receive the detection signal from the signal simulator and does not issue a third alarm signal, it is determined that the alarm function of the generator set controller is faulty.

[0070] Step S302: If the signal value of the detection signal of the above-mentioned signal simulator exceeds the corresponding predetermined range and the above-mentioned generator set controller does not issue a fourth alarm signal, it is determined that the alarm function of the above-mentioned generator set controller has malfunctioned.

[0071] Specifically, the unit fault signals can be set on the panel. The fault setting method uses a toggle switch. In addition to circuit breakage faults, fault settings can also be set for some sensors that are out of the predetermined range or distorted through the signal simulator.

[0072] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the test method for the generator set controller of this application will be described in detail below with reference to specific embodiments.

[0073] This embodiment relates to a specific test method for a generator set controller, such as... Figure 3 As shown, it includes the following steps:

[0074] Step S1: Single-unit simulated generator start-up: The user operates the switch to trigger the start-up conditions; the generator controller outputs a start-up signal; if no fault is set, the PLC collects the corresponding signal and controls the three-phase power supply to generate a power generation signal; the generator controller issues a closing command; the ATS simulation module simulates automatic switching, and the three-phase power supply and the generator controller are connected. During the start-up and operation of the unit, if any fault is set, the generator controller will generate corresponding alarm information.

[0075] Step S2: Single-unit simulated unit shutdown: The user operates the switch to trigger the shutdown condition; the generator set controller sends a trip signal; the ATS simulation module simulates automatic switching; the three-phase power supply is disconnected from the generator set controller; if there is no fault setting, the PLC stops the three-phase power supply output after acquiring the signal.

[0076] Step S3: Parallel Simulation Unit Start-up: After the first three-phase power supply (main unit) starts up, the corresponding ATS simulation module closes. The second three-phase power supply (auxiliary unit) starts up. The output signal of the first three-phase power supply is used as the busbar signal and connected to the busbar voltage monitoring point of the second generator unit controller. If the settings of the first three-phase power supply are the same as those of the second three-phase power supply, that is, the generated signals are consistent, then the ATS simulation module corresponding to the second three-phase power supply closes.

[0077] Step S4: Disconnecting the communication line will generate a communication failure alarm; if the two three-phase sources are set differently during synchronization, synchronization will fail; if the two three-phase sources are set to different power during parallel operation, a reverse power / overpower alarm will be generated; if the closing feedback is set to disconnect during the closing process, a closing failure alarm will be generated; if the two three-phase sources are set differently during synchronization, the setting knob can be manually adjusted to make them the same to simulate speed regulation; the unit fault signal can be set on the panel, and the fault setting method uses a toggle switch. In addition to circuit breakage faults, some sensor out-of-calibration or distortion faults can also be set through the simulator.

[0080] The following describes the testing apparatus for the generator set controller provided in the embodiments of this application. The apparatus includes:

[0081] A three-phase power supply is electrically connected to the generator set controller. The three-phase power supply is used to simulate the generator set outputting a power generation signal to the generator set controller.

[0082] Specifically, the functions of the generator set controller include controlling the start and stop of the generator set, as well as controlling the generator set to connect to and disconnect from the power transmission circuit. These functions are achieved by issuing corresponding control signals, namely start signal, stop signal, closing signal, and opening signal. The generator set outputs a power generation signal through a three-phase power supply to simulate the generator set output, thereby testing the functions of the generator set controller.

[0083] The analog device is communicatively connected to the generator set controller. The analog device is used to output analog signals in response to control signals issued by the generator set controller. The control signals include start signals, stop signals, closing signals, and opening signals. The start signal controls the start of the three-phase power supply; the stop signal controls the stop of the three-phase power supply; the closing signal controls the connection of the transmission line between the three-phase power supply and the generator set controller; the opening signal controls the disconnection of the transmission line between the three-phase power supply and the generator set controller; and the power generation signal is any one or more of voltage signals, frequency signals, and phase signals.

[0084] Specifically, in response to the aforementioned control signal, the analog device outputs an analog signal. For example, a three-phase power supply outputs a generating signal in response to a start signal, or a three-phase power supply stops outputting a generating signal in response to a stop signal.

[0085] The host computer is communicatively connected to both the generator set controller and the analog device. The host computer is used to determine whether the generator set controller is faulty based on the control signals and the analog signals.

[0086] Specifically, after the generator set controller sends a control signal, it can determine whether the function corresponding to the control signal of the generator set controller is normal by whether the analog device responds to the control signal and feeds back the corresponding analog signal. After testing all functions, it can be determined whether the generator set controller is faulty and the corresponding fault type.

[0087] In the aforementioned test device for the generator set controller, a three-phase power supply is electrically connected to the generator set controller. This three-phase power supply is used to simulate the generator set outputting a power generation signal to the generator set controller. An analog device is communicatively connected to the generator set controller. This analog device is used to control the output of analog signals in response to control signals issued by the generator set controller. These control signals include a start signal, a stop signal, a closing signal, and a opening signal. The start signal controls the start of the three-phase power supply; the stop signal controls the stop of the three-phase power supply; the closing signal controls the connection of the transmission line between the three-phase power supply and the generator set controller; and the opening signal controls the disconnection of the transmission line between the three-phase power supply and the generator set controller. The power generation signal is any one or more of a voltage signal, a frequency signal, and a phase signal. A host computer is communicatively connected to both the generator set controller and the analog device. The host computer is used to determine whether the generator set controller is faulty based on the control signals and the analog signals. This device uses the control signal sent by the generator set controller to cause the analog device to respond to the control signal and output a corresponding analog signal, simulating the control process of the generator set controller. Based on the control signal and the analog signal, it can determine whether the generator set controller is faulty, thus realizing the functional test of the generator set controller and solving the problem of difficulty in testing the function of the generator set controller in the prior art.

[0088] To test the functions corresponding to the generator set controller's closing and opening signals, in one optional embodiment, the simulation device further includes an ATS simulation module. This ATS simulation module simulates power switching via an ATS system. The simulated signals include the generator signal, the on-feedback signal, and the off-feedback signal. The host computer includes:

[0089] The first control module is used to control the three-phase power supply to output the power generation signal in response to the start signal, and to control the ATS analog module to conduct the transmission lines of the three-phase power supply and the generator set controller and output the conduction feedback signal in response to the closing signal.

[0090] The second control module is used to control the three-phase power supply to stop outputting the power generation signal in response to the shutdown signal, and to control the ATS analog module to disconnect the transmission lines of the three-phase power supply and the generator set controller and output the disconnection feedback signal in response to the trip signal.

[0091] Specifically, the ATS simulation module is used to simulate ATS power switching, controlling the connection and disconnection of the transmission line between the three-phase power supply and the generator controller. When the user operates the switch, triggering the starting conditions, the generator controller sends a start signal. In response to this start signal, the generator controller controls the three-phase power supply to output the generated signal. After the three-phase power supply starts without fault, the generator controller sends a closing signal, controlling the ATS simulation module to connect the transmission line between the three-phase power supply and the generator controller, and outputs the connection feedback signal to indicate successful connection. The generator controller then receives the generated signal from the three-phase power supply and can test the power generation. To test whether the generator set controller can properly control the generator set's start-up and circuit breaker closing functions, similarly, when the user operates the switch to trigger the shutdown condition, the generator set controller can send a trip signal to control the ATS simulation module to disconnect the three-phase power supply and the generator set controller's transmission lines, and output the disconnection feedback signal to indicate that the tripping was successful. The generator set controller will no longer receive the three-phase power supply's output power signal. Upon receiving the disconnection feedback signal, the generator set controller can send a shutdown signal. In response to the shutdown signal, the three-phase power supply will stop outputting the power signal, thus testing whether the generator set controller can properly control the generator set's shutdown and circuit breaker closing functions.

[0092] To determine whether the generator set start-up control function is working properly, in one optional implementation, the host computer further includes:

[0093] The first determining module is used to determine that the generator set controller's function of controlling the generator set to start malfunctions after responding to the start signal, controlling the three-phase power supply to output the power generation signal, and responding to the closing signal, controlling the ATS analog module to conduct the transmission lines of the three-phase power supply and the generator set controller and output the conduction feedback signal, in the case that the analog device does not receive the start signal and / or the generator set controller does not receive the power generation signal.

[0094] The second determining module is used to determine that the generator set controller's function of controlling the generator set to start is fault-free when the above-mentioned analog device receives the above-mentioned start signal and the above-mentioned generator set controller receives the above-mentioned power generation signal.

[0095] Specifically, if the aforementioned analog device does not receive the aforementioned start signal, it indicates that the generator set controller cannot send the start signal normally, and the start control function is faulty. If the aforementioned analog device receives the aforementioned start signal, but the aforementioned generator set controller does not receive the aforementioned power generation signal, then the closing function of the transmission line connecting the aforementioned three-phase power supply and the aforementioned generator set controller is faulty. Only when the aforementioned analog device receives the aforementioned start signal and the aforementioned generator set controller receives the aforementioned power generation signal, it indicates that the generator set starts normally and outputs a power generation signal to the generator set controller, that is, both the start control function and the closing control function are fault-free.

[0096] To test the function of the generator set controller in balancing the output power of parallel generator sets, in one optional implementation, the host computer further includes:

[0097] The third determining module is used to determine that the generator set controller's function of controlling the generator set to stop outputting the generating signal is faulty after responding to the shutdown signal, controlling the three-phase power supply to stop outputting the generating signal, and responding to the tripping signal, controlling the ATS analog module to disconnect the transmission lines of the three-phase power supply and the generator set controller and outputting the disconnection feedback signal. In the case that the analog device does not receive the shutdown signal and / or the generator set controller receives the generating signal, the generator set controller's function of controlling the generator set to stop is faulty.

[0098] The fourth determining module is used to determine that the generator set controller's function of controlling the generator set to shut down is fault-free when the above-mentioned analog device receives the above-mentioned shutdown signal and the above-mentioned generator set controller does not receive the above-mentioned analog signal.

[0099] Specifically, if the aforementioned analog device does not receive the aforementioned shutdown signal, it indicates that the generator set controller cannot normally issue a shutdown signal, and the shutdown control function is faulty. If the aforementioned analog device receives the aforementioned shutdown signal and the aforementioned generator set controller receives the aforementioned power generation signal, then the tripping function of disconnecting the aforementioned three-phase power supply and the transmission line of the aforementioned generator set controller is faulty. Only if the aforementioned analog device receives the aforementioned shutdown signal and the aforementioned generator set controller does not receive the aforementioned analog signal, it indicates that the output power generation signal cannot be sent to the generator set controller and the generator set shuts down normally, that is, both the shutdown control function and the tripping control function are fault-free.

[0100] To test the generator set alarm function, in one optional implementation, the host computer further includes:

[0101] The fifth determination module is used to determine that the alarm function of the generator set controller is malfunctioning after the ATS simulation module controls the three-phase power supply and the transmission line of the generator set controller to conduct and outputs the conduction feedback signal, and the generator set controller does not receive the conduction feedback signal and does not issue the first alarm signal.

[0102] The sixth determination module is used to determine that the alarm function of the generator set controller has malfunctioned after the ATS simulation module disconnects the three-phase power supply and the transmission line of the generator set controller and outputs the disconnection feedback signal, and the generator set controller does not receive the disconnection feedback signal and does not issue a second alarm signal.

[0103] Specifically, if the generator set controller does not receive the aforementioned conduction feedback signal or the aforementioned disconnection feedback signal, it will issue a corresponding alarm signal. If no alarm signal is issued, it indicates that the alarm function is faulty. Of course, this is not limited to the absence of feedback; other faults can also issue corresponding alarm signals to remind personnel to perform maintenance.

[0104] To test the function of the generator set controller in balancing the output power of parallel generator sets, in one optional embodiment, the three-phase power supply includes a first three-phase power supply and a second three-phase power supply; the generator set controller includes a first generator set controller and a second generator set controller; the ATS simulation module includes a first ATS simulation module and a second ATS simulation module; and the host computer further includes:

[0105] The third control module is used to control the first three-phase power supply to output a first power generation signal in response to the first start signal output by the first generator set controller, and to control the first ATS analog module to conduct the transmission lines of the first three-phase power supply and the first generator set controller and output a first conduction feedback signal in response to the first closing signal output by the first generator set controller.

[0106] The fourth control module is used to control the second three-phase power supply to output a second power generation signal in response to the second start signal output by the second generator set controller, and to control the second ATS analog module to conduct the transmission lines of the second three-phase power supply and the second generator set controller and output a second conduction feedback signal in response to the second closing signal output by the second generator set controller.

[0107] Specifically, there can be multiple generator sets. After the single-unit mode function test of a single generator set is completed, it is also necessary to test the dual-unit parallel function test of two generator sets connected in parallel. The first three-phase power supply and the second three-phase power supply are started and connected in parallel respectively. Based on whether the output power of the first three-phase power supply and the second three-phase power supply are the same, the function of the generator set controller to balance the output power of the parallel generator sets can be tested.

[0108] To test the function of the generator set controller in balancing the output power of parallel generator sets, in one optional implementation, the host computer further includes:

[0109] The seventh determining module is configured to, in response to the second start signal output by the second generator set controller, control the second three-phase power supply to output a second power generation signal, and in response to the second closing signal output by the second generator set controller, control the second ATS analog module to conduct the transmission lines of the second three-phase power supply and the second generator set controller and output a second conduction feedback signal, and determine that the communication function of the first generator set controller is faulty if the first generator set controller does not receive the first feedback signal from the second generator set controller, and / or determine that the communication function of the second generator set controller is faulty if the second generator set controller does not receive the second feedback signal from the first generator set controller, wherein the first feedback signal is the first power generation signal forwarded by the first generator set controller to the second generator set controller, and the second feedback signal is the second power generation signal forwarded by the second generator set controller to the first generator set controller;

[0110] The eighth determining module is used to determine that the synchronization function of the first generator set controller and the second generator set controller has failed when the first power generation signal and the second power generation signal are different.

[0111] The ninth determining module is used to determine whether the first generator set controller or the second generator set controller has a reverse power fault when the output power of the first three-phase power supply and the output power of the second three-phase power supply are different.

[0112] Specifically, the first generator set controller and the second generator set controller are communicatively connected to determine whether the generation signals of the two parallel three-phase power supplies are consistent. If the feedback signal between the first and second generator set controllers cannot be received, it indicates a communication function failure. If the communication function is not faulty, but the first and second generation signals are different, it indicates a synchronization function failure between the first and second generator set controllers. Furthermore, if the settings of the first and second three-phase power supplies are different during synchronization, the setting knob can be manually adjusted to make them the same, simulating speed regulation. Additionally, if the output power of the first and second three-phase power supplies is different, a reverse power fault occurs.

[0114] The tenth determination module is used to determine whether the generator set controller is faulty after determining whether the generator set controller is faulty based on the control signal and the analog signal. If the generator set controller does not receive the detection signal from the signal simulator and does not issue a third alarm signal, the module determines that the alarm function of the generator set controller is faulty.

[0115] The eleventh determination module is used to determine that the alarm function of the generator set controller is malfunctioning when the signal value of the detection signal of the above-mentioned signal simulator exceeds the corresponding predetermined range and the generator set controller does not issue a fourth alarm signal.

[0116] Specifically, the unit fault signals can be set on the panel. The fault setting method uses a toggle switch. In addition to circuit breakage faults, fault settings can also be set for some sensors that are out of the predetermined range or distorted through the signal simulator.

[0117] The aforementioned generator set controller testing device includes a processor and a memory. The receiving unit, control unit, and determining unit are all stored as program units in the memory, and the processor executes these program units stored in the memory to achieve the corresponding functions. All of the above modules are located in the same processor; alternatively, the modules may be located in different processors in any combination.

[0147] This application also provides a computer program product that, when executed on a data processing device, is suitable for executing an initialization program having at least the following method steps:

[0148] Step S201: Receive control signals from the generator set controller. The control signals include a start signal, a stop signal, a closing signal, and a opening signal. The start signal is a signal to control the three-phase power supply to start. The stop signal is a signal to control the three-phase power supply to stop. The closing signal is a signal to control the connection of the transmission line between the three-phase power supply and the generator set controller. The opening signal is a signal to control the disconnection of the transmission line between the three-phase power supply and the generator set controller. The three-phase power supply is used to simulate the generator set outputting a power generation signal. The power generation signal is any one or more of a voltage signal, a frequency signal, and a phase signal.

[0149] Specifically, the functions of the generator set controller include controlling the start and stop of the generator set, as well as controlling the generator set to connect to and disconnect from the power transmission circuit. These functions are achieved by issuing corresponding control signals, namely start signal, stop signal, closing signal, and opening signal. The generator set outputs a power generation signal through a three-phase power supply to simulate the generator set output, thereby testing the functions of the generator set controller.

[0150] Step S202: In response to the control signal, the analog device is controlled to output an analog signal. The analog device includes at least the three-phase power supply. The analog signal is a feedback signal generated in response to the control signal.

[0151] Specifically, in response to the above control signal, the analog device outputs an analog signal. For example, the three-phase power supply outputs a power generation signal in response to the start signal, or the three-phase power supply stops outputting a power generation signal in response to the stop signal. In step S203, it is determined whether the generator set controller is faulty based on the above control signal and the above analog signal.

[0152] Specifically, after the generator set controller sends a control signal, it can determine whether the function corresponding to the control signal of the generator set controller is normal by whether the analog device responds to the control signal and feeds back the corresponding analog signal. After testing all functions, it can be determined whether the generator set controller is faulty and the corresponding fault type.
