[0057] Quasi-synchronous grid connection is a key technology for the safe and reliable connection of power generation equipment and the power grid in a power system. Quasi-synchronous grid connection modules ensure that the power generation equipment and the power grid are synchronized before grid connection by detecting the voltage amplitude, phase angle, and frequency of both, thus achieving safe and reliable grid connection. However, existing grid connection schemes have many problems, mainly in the following aspects:

[0058] (1) High risk of manual operation: There are two ways to connect to the grid at the same time: one is to build the generator set with a bypass; the other is to build it with an external bypass. When using the above methods to achieve secondary grid connection, the power cable must be connected to ensure that the bypass can meet the current carrying capacity.

[0059] (2) High operational complexity: The output cable of the power generation equipment needs to be manually connected to the quasi-synchronous grid connection module and the anti-grid connection point. The operation is cumbersome and grid connection failure is easily caused by incorrect connection.

[0060] (3) In narrow spaces, it is impossible to achieve live connection, which affects the implementation of secondary grid connection.

[0061] (4) Difficult equipment handling: The existing quasi-synchronous grid-connected platforms are large in size and heavy in weight, and the handling and installation process is complicated, especially in complex terrain or emergency tasks, which greatly limits the improvement of work efficiency.

[0062] Based on this, this application provides a generator synchronization device that enables rapid grid connection between the generator vehicle and the mains power grid.

[0063] In one embodiment, a generator synchronization device is provided, such as... Figure 1As shown, the aforementioned generator synchronizing device includes: a housing 10, an interface module 20, a control module 30, and an indicator module 40; the interface module 20 is located on the outside of the housing 10, while the control module and indicator module 40 are located inside the housing 10; the interface module 20 is connected to the control module and indicator module 40 respectively; the interface module 20 is used to connect to the low-voltage main switch of the generator and the mains power supply, and to transmit the electrical parameters of the generator and the mains power supply to the control module 30 and indicator module 40; the indicator module 40 is used to indicate the working status of the generator and the mains power supply, and is also used for touch-based... The system issues a working status control command, generates a working status control signal, and sends the working status control signal to the generator vehicle through the interface module 20 to control the working status of the generator vehicle; the control module 30 is used to set the base load value of the generator vehicle; the base load value is set based on the electrical parameters of the mains power; the indicator module 40 is also used to output a control signal according to the triggered control command when the difference between the electrical parameters of the generator vehicle and the base load value is less than a preset difference, and transmit the control signal to the generator vehicle through the interface module 20 to complete the secondary grid connection of the generator vehicle.

[0064] The electrical parameters of the generator vehicle may include voltage, frequency, load power, etc.

[0065] In the embodiments of this application, Figure 1 A schematic diagram of the generator synchronizing device from multiple angles, such as... Figure 1 As shown, the interface module 20 is located on the outside of the housing 10, while the control module 30 and the indicator module 40 are located inside the housing 10. The interface module 20 is connected to the control module 30 and the indicator module 40, respectively. The interface module 20 is used to make electrical connections with the generator vehicle and the low-voltage main switch of the mains power, and can transmit the electrical parameters of the generator vehicle and the mains power to the control module 30 and the indicator module 40 in real time.

[0066] In this embodiment, the cables extending from the interface module 20 are connected to the control interface of the generator car and the sampling interface of the mains low-voltage switch, respectively, to achieve signal interaction. The indicator module 40 is equipped with corresponding display elements to indicate the working status of the generator car and the mains power, such as the energized status of the power supply side, the energized status of the load side, and the open / closed status of the generator car switch. The operator can trigger working status control commands through the operation buttons on the indicator module 40. The indicator module 40 generates corresponding control signals accordingly and sends them to the generator car through the interface module 20, thereby remotely controlling the start-up, shutdown, and other operations of the generator car.

[0067] In this embodiment, the control module 30 has a parameter setting function, which can set the base load value of the generator vehicle based on the mains electrical parameters collected by the interface module 20. The setting of the base load value is intended to enable the generator vehicle to smoothly bear the load after being connected to the grid, so as to avoid impacting the generator set.

[0068] In this embodiment, during the secondary grid connection process, the real-time electrical parameters of the generator truck are continuously monitored and displayed on the indicator module 40. When the deviation between the electrical parameters of the generator truck and the preset base load value is less than the preset allowable difference, the indicator module 40 can output a corresponding control signal according to the grid connection control command triggered by the operator, and transmit the control signal to the generator truck through the interface module 20, controlling the generator truck to automatically complete the synchronous closing operation with the mains power, thereby achieving a smooth secondary grid connection.

[0069] The aforementioned generator synchronizing device includes: a housing, an interface module, a control module, and an indicator module. The interface module is located on the outside of the housing, while the control module and indicator module are located inside the housing. The interface module is connected to the control module and indicator module, respectively. The interface module is used to connect to the low-voltage main switch of the generator and the mains power supply, and to transmit the electrical parameters of the generator and the mains power supply to the control module and indicator module. The indicator module is used to indicate the working status of the generator and the mains power supply, and also to generate a working status control signal based on a triggered working status control command, and send the working status control signal to the generator through the interface module to control the working status of the generator. The control module is used to set the base load value of the generator. The base load value is set based on the electrical parameters of the mains power supply. The indicator module is also used to output a control signal according to a triggered control command when the difference between the electrical parameters of the generator and the base load value is less than a preset difference, and transmit the control signal to the generator through the interface module to complete the secondary grid connection of the generator. By integrating the interface module, control module, and indicator module into a portable housing, centralized and automated management of generator truck grid connection operations is achieved, improving operational convenience and safety. The indicator module can display the real-time operating status of the mains power and the generator truck and remotely control the generator truck's start and stop. The control module can set the base load value of the generator truck based on the collected mains power electrical parameters, avoiding the impact on the generator set caused by the moment of grid connection. Furthermore, during the secondary grid connection process, the generator truck synchronization device can monitor the deviation between the generator truck's electrical parameters and the preset base load value, and output control signals to complete the synchronization closing when the conditions are met, thereby reducing the difficulty of manual grid connection operations and the risk of misoperation, and ensuring the smooth and reliable load transfer process.

[0070] In one embodiment, such as Figure 2 As shown, the control module 30 includes: a display panel 301 and a first button component 302; the first button component 302 is used to adjust the base load value of the generator vehicle based on the button command triggered by the user; the display panel 301 is used to display the base load value of the generator vehicle, the electrical parameters of the generator vehicle, and the electrical parameters of the mains power.

[0071] In this embodiment, both the display panel 301 and the first button assembly 302 are arranged on the operating surface of the housing 10, facilitating real-time viewing and interaction by the user. After the interface module 20 transmits the collected electrical parameters of the generator vehicle and the mains electrical parameters to the control module 30, the data is displayed in real-time on the display panel 301, providing the user with intuitive data reference. The first button assembly 302 receives button commands triggered by the user. When the user needs to adjust the output of the generator vehicle according to the mains load, they can modify the base load value set by the controller inside the generator vehicle by operating the first button assembly 302. During the adjustment process, the display panel 301 synchronously updates and displays the current base load value, enabling the user to accurately set the base load value to the expected range, thereby ensuring that the generator vehicle can smoothly bear the load after grid connection and avoiding impact on the generator set due to improper parameter settings.

[0072] In the above-mentioned embodiments, a human-machine interface is constructed by setting a display panel and a first button component, which enables operators to simultaneously monitor the real-time electrical parameters of the mains power and the generator vehicle on the sampling box without having to go deep into the generator vehicle. Based on the displayed data, the operator can accurately adjust the base load value of the generator vehicle through the button group, thereby improving the convenience and accuracy of parameter setting. It also ensures that the base load value can accurately match the actual situation of the mains power load, reducing the risk of grid connection impact caused by parameter missetting, and providing reliable data support for the subsequent stable grid connection and secondary grid connection control of the generator vehicle.

[0073] In one embodiment, such as Figure 3 As shown, the aforementioned indicating module 40 includes: a grid connection knob 401, the first position of which represents primary grid connection, and the second position of which represents secondary grid connection; when the difference between the electrical parameters of the generator vehicle and the base load value is less than a preset difference, and the low-voltage main switch of the mains power is disconnected, a control signal is output based on the user's rotation operation of the grid connection knob 401, and the control signal is transmitted to the generator vehicle through the interface module 20 to complete the secondary grid connection of the generator vehicle; the rotation operation is to rotate the indicating position of the grid connection knob 401 from primary grid connection to secondary grid connection.

[0074] In this embodiment, the indicating module 40 is equipped with a grid connection knob 401, which has at least two position states, wherein the first position represents a primary grid connection mode and the second position represents a secondary grid connection mode. The grid connection knob 401 is associated with the internal circuitry and control logic of the indicating module 40 and is used to receive mode switching commands from the user. After the generator completes primary grid connection and enters islanded operation, i.e., when the mains low-voltage switch is open and the load is powered solely by the generator, the control module 30 continuously monitors the deviation between the generator's electrical parameters and the preset base load value. When the deviation is less than a preset allowable difference, the indicating module 40 enters a ready state for secondary grid connection. Furthermore, by rotating the grid connection knob 401, the user rotates the indicator position of the grid connection knob 401 from the first position representing primary grid connection to the second position representing secondary grid connection. The indicator module 40 then triggers the corresponding control signal based on the rotation operation and transmits the control signal to the control system of the generator vehicle through the interface module 20. The generator vehicle then automatically performs synchronous closing with the mains power to complete the secondary grid connection process.

[0075] In the above-mentioned application embodiments, by setting a grid connection knob with primary and secondary grid connection position indicators, the complex mode switching and command triggering functions are integrated, simplifying the operation process; and ensuring that the control signal is only issued when the grid connection conditions are met and the user actively switches the knob, thereby improving the convenience of operation. At the same time, through the dual verification of the physical knob gear limit and electrical logic, the risk of accidental triggering of grid connection commands when the conditions are not met is avoided, providing a clear, safe and reliable operation guarantee for the secondary grid connection operation of the generator vehicle.

[0076] In one embodiment, such as Figure 3 As shown, the above-mentioned indicator module 40 further includes: an indicator component 402 and a button component 403; the indicator component 402 is used to indicate the working status of the generator car and the low-voltage main switch based on the electrical parameters of the generator car; the button component 403 is used to trigger control commands for the working status of the generator car.

[0077] In this embodiment, the indicator module 40 further includes an indicator component 402 and a button component 403. Both the indicator component 402 and the button component 403 are located on the operation panel of the housing 10 for easy observation and operation by the operator. The indicator component 402 is connected to the interface module 20 and is used to receive and display the real-time operating status of the generator car and the mains low-voltage switch. Specifically, the indicator component 402 may include indicator lights or display areas of different colors to reflect the energized status of the power supply side, the energized status of the load side, the open / closed position of the generator car switch, and fault alarms, respectively, so that the operator can intuitively grasp the operation status of the entire power supply system. The button component 403 is connected to the control circuit within the indicator module 40 and is used to receive operation commands triggered by the user. By pressing different buttons, the operator can generate corresponding generator car operating status control commands, such as generator car start commands or shutdown commands. After being processed by the indicator module 40, the commands are transmitted to the generator car through the interface module 20 to realize remote control of the generator car's start and stop. The indicator component 402 and the button component 403 work together to enable the operator to perform control operations while observing the equipment status.

[0078] For example, the circuit diagram of the button assembly 403 is as follows: Figure 4 As shown, the circuit diagram of the indicator component 402 is as follows: Figure 5 As shown.

[0079] In the above-mentioned embodiments, the indicator component can provide real-time and intuitive feedback on the electrical status and opening / closing position of the generator car and the low-voltage main switch, enabling operators to fully grasp the system operating conditions without relying on additional instruments. The button component provides remote control capability for starting and stopping the generator car, thereby achieving the unification of status monitoring and operation control. Operators can execute control commands while observing the real-time status of the equipment, improving work efficiency and convenience, and reducing the risk of misoperation caused by unclear status, thereby enhancing the safety and reliability of the generator car synchronizing device during grid connection operation.

[0080] In one embodiment, such as Figure 6 As shown, the above-mentioned indicator component 402 includes: a live indicator light group 4021 and a switch status indicator light group 4022; the live indicator light group 4021 is used to indicate the live status of the power supply side and the load side of the low-voltage main switch based on the electrical parameters of the mains power; the switch status indicator light group 4022 is used to indicate the switch status of the generator car based on the electrical parameters of the generator car.

[0081] In this embodiment, the indicator module 40 includes an indicator component 402, which can be divided into a live indicator light group 4021 and a switch status indicator light group 4022. The live indicator light group 4021 is connected to the interface module 20 and is used to receive electrical parameters from the mains power side, and accordingly indicate the live status of the low-voltage main power supply side and the load side in real time. The switch status indicator light group 4022 is connected to the interface module 20 and is used to receive electrical parameters from the generator car, and accordingly indicate the open / closed status of the generator car output switch in real time.

[0082] Optionally, the energized indicator group 4021 includes: a power supply side energized indicator 4023 and a load side energized indicator 4024. When the power supply side energized indicator 4023 is lit, it indicates that the power supply side of the low-voltage main switch is energized; when the load side energized indicator 4024 is lit, it indicates that the load side of the low-voltage main switch is energized. The power supply side energized indicator 4023 is connected to the line in the interface module 20 that collects the mains power supply side parameters. When the power supply side of the low-voltage main switch detects voltage at the grid input terminal, this indicator lights up, indicating that the mains input side is energized. The load side energized indicator 4024 is connected to the line in the interface module 20 that collects the load side parameters of the low-voltage main switch. When there is voltage on the load side busbar or line, this indicator lights up to indicate the current energized state of the load side.

[0083] For example, when the mains power is supplied normally, the power supply side energized indicator 4023 lights up; when the generator is connected to the grid or the mains power is restored, the load side energized indicator 4024 lights up accordingly, so that the operator can clearly distinguish the energized status of the high and low voltage sides.

[0084] Optionally, the switch status indicator group 4022 includes: a first generator car closing indicator 4025 and a second generator car opening indicator 4026. The first generator car closing indicator 4025 and the second generator car opening indicator 4026 have different colors. When the first generator car closing indicator 4025 is lit, it indicates that the generator car switch is in the closed position; when the second generator car closing indicator is lit, it indicates that the generator car switch is in the open position. The first generator car closing indicator 4025 is connected to the line in the interface module 20 that collects the status of the generator car switch. When the output switch of the generator car detects that it is in the closed position, this indicator light is lit. Similarly, the second generator car opening indicator 4026 is connected to the corresponding signal acquisition line in the interface module 20. When the output switch of the generator car is in the open position, this indicator light is lit.

[0085] For example, a red light indicates that the generator switch is in the closed position, and a green light indicates that the generator switch is in the open position. With these two sets of indicator lights, operators can intuitively understand the status of key nodes in the entire power supply system without additional measurements.

[0086] In the above-mentioned application embodiments, the complex electrical state is converted into an intuitive optical signal, which reduces the cognitive burden and probability of misjudgment of the operator, and provides clear status basis for each step of the grid connection operation, thereby improving the convenience of operation and further strengthening the safety guarantee capability of the whole device.

[0087] In one embodiment, such as Figure 6 As shown, the button assembly 403 includes: an operation button assembly 4031 and a power switch 4032; the operation button assembly 4031 is used to trigger a control command for the working status of the generator car; the power switch 4032 is used to trigger a control command for the power supply of the synchronous device of the generator car.

[0088] In this embodiment, the operation button assembly 4031 is connected to the control circuit in the indicator module 40 to receive the generator car working status control command triggered by the user and transmit the command to the generator car through the interface module 20; the power switch 4032 is set on the operation panel of the housing 10 and is connected to the power supply line inside the generator car synchronizing device to control the power supply of the input device itself. The operator can control whether the device is powered on and working by switching the power supply.

[0089] Optionally, the operation button assembly 4031 includes: a generator car start button 4033 and a generator car stop button 4034; the generator car start button 4033 is used to trigger a command to start the generator car; the generator car stop button 4034 is used to trigger a command to stop the generator car. The generator car start button 4033 is connected to the circuit corresponding to the start control logic in the indicator module 40. When the user presses the button, a start command is generated and sent to the generator car via the interface module 20 to control the generator car generator set to start running; the generator car stop button 4034 is connected to the circuit corresponding to the stop control logic. When pressed, a stop command is generated and transmitted to the generator car to control the generator car generator set to stop running.

[0090] In the above-mentioned embodiments, the power switch independently controls the power supply of the generator synchronizing device, ensuring that the equipment is powered off when not in use; the generator start button and stop button in the operation button assembly are designed independently, allowing operators to remotely control the start and stop of the generator through simple pressing actions, avoiding direct contact with the local control panel of the generator, preventing the risk of accidental touch through physical isolation, making remote start and stop control more reliable, and improving the convenience and safety of operation during grid connection.

[0091] In one embodiment, such as Figure 7As shown, the interface module 20 includes: a communication cable interface 201 and a sampling control line interface 202; the communication cable interface 201 is used to connect to the generator vehicle via a communication cable; the sampling control line interface 202 is used to connect to the low-voltage main switch of the mains power via a sampling control line.

[0092] In this embodiment, the communication cable interface 201 is used to establish a wired connection with the operation panel or control system of the generator vehicle via a communication cable, enabling data interaction and control signal transmission between the device and the generator vehicle. The sampling control line interface 202 is used to connect to a modified sampling interface on the low-voltage main switch on the mains side via a sampling control cable, thereby enabling the acquisition of mains electrical parameters and the control of the opening and closing of the low-voltage main switch. Optionally, the sampling control line interface 202 includes a first interface and a second interface. The first interface is used to connect to the power supply side of the low-voltage main switch, and the second interface is used to connect to the load side of the low-voltage main switch.

[0093] For example, a circuit diagram of the communication cable interface 201 that connects to the generator vehicle is shown below. Figure 8 As shown, 3 represents the on / off state of the mains power switch, 4 represents the on / off state of the generator car switch, 5 represents the remote start signal of the generator car, 6 represents the shield for communication with the unit controller, 7 represents L for CAN communication, 8 represents H for CAN communication, 9 represents 24V taken from the generator car power supply, and 10 represents 0V taken from the generator car power supply.

[0094] In the above-mentioned embodiments, the independent interface design avoids signal confusion and wiring errors, enabling on-site operators to quickly identify and complete the connection of the corresponding cables, thereby improving the convenience and reliability of equipment deployment.

[0095] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.
