[0024] This application provides a power supply control device, which includes: Power supply equipment; Multiple switching devices, each of which has its input terminal electrically connected to the output terminal of the power supply device, and each of which has its output terminal electrically connected to the corresponding load connection terminal of the power supply control device. In the case where the power supply control device is in load balancing mode, the first and second parts of multiple switching devices are simultaneously supplied with electrical energy from the target power supply device in the power supply device.
[0025] In this embodiment, the power supply device can be a generator, such as a thermal power generator, a wind power generator, a diesel generator, etc., which is not limited here.
[0026] In this embodiment, as Figure 1As shown, there are two power supply devices, namely power supply device 1a and power supply device 1b, and two switching devices, namely switching device 2a and switching device 2b.

[0028] In some embodiments, the switching device further includes a plurality of main switches, the first end of each main switch being electrically connected to the output end of the corresponding power supply device, and the second end of each main switch being electrically connected to the first end of the corresponding single-sided switch.
[0029] In this embodiment, as Figure 2 As shown, the power supply devices are power supply devices G1-Government Power Supply Device GN+1, and multiple main switches are main switches DQ13-DQ(N+1)3. The output terminal of power supply device G1 is electrically connected to the first terminal of main switch DQ13, the output terminal of power supply device GN is electrically connected to the first terminal of main switch DQN3, and the output terminal of power supply device G(N+1) is electrically connected to the first terminal of main switch DQ(N+1)3.
[0030] In this embodiment, by setting a main switch, rapid electrical isolation of the power supply device is achieved, serving as the last switch to confirm connection when the power supply device needs to be used as a backup output.
[0031] In some embodiments, the switching device includes a plurality of single-sided switches, wherein a first end of each single-sided switch is used to be electrically connected to the output end of a corresponding power supply device, and a second end of each single-sided switch is used to be electrically connected to the output end of the switching device.
[0032] In this embodiment, as Figure 2As shown, the power supply device is power supply device G1-power supply device GN+1, and the multiple single-sided switches are single-sided switches DQ11-single-sided switch DQ(N+1)1.

[0033] In this embodiment, the single-sided switch is installed between the power supply device and the busbar of the corresponding section (busbar A section or busbar B section) to realize the connection and disconnection of the corresponding power supply device.
[0034] In some embodiments, the switching device further includes a bus switch circuit, wherein the second end of each single-sided switch is electrically connected to the corresponding input end of the bus switch circuit, and the output end of the bus switch circuit serves as the output end of the switching device.
[0035] In this embodiment, by setting a bus switch circuit, the safety factor of the power supply device for supplying power to the load can be further improved.
[0036] In some embodiments, the bus switch circuit includes a plurality of bus input switches, a bus, and a bus output switch. The first end of each bus input switch is electrically connected to the second end of the corresponding single-sided switch. The second end of each bus switch is electrically connected to the corresponding input end of the bus. The output end of the bus is electrically connected to the first end of the bus output switch. The second end of the bus output switch serves as the output end of the bus switch circuit.
[0037] In this embodiment, as Figure 2 As shown, the bus switch circuits are bus switch circuit 4a and bus switch circuit 4b. Bus switch circuit 4a includes bus input switches Q11-Q1(N+1), the bus of bus switch circuit 4a is bus A, and the bus output switch of bus switch circuit 4a is bus output switch QL12. Bus switch circuit 4b includes bus input switches Q21-Q2(N+1), the bus of bus switch circuit 4b is bus B, and the bus output switch of bus switch circuit 4b is bus output switch QL22. When the main switch DQ13 is closed and the single-sided switch DQ11 is closed, the bus input switch Q11 and the bus output switch QL22 are closed, enabling the power supply device to provide power to the load connection terminal of load 3.
[0038] In this embodiment, by setting a bus input switch, a bus, and a bus output switch, the safety factor of the power supply device for supplying power to the load can be further improved.
[0039] In some embodiments, the power supply control device further includes a tie switch, which is disposed between the busbars of any two switching devices.
[0040] In this embodiment, as Figure 2 As shown, the tie switch includes tie switch QL11 and tie switch QL21. The first end of tie switch QL11 is connected to bus A, the second end of tie switch QL11 is electrically connected to the first end of tie switch QL21, and the second end of tie switch QL21 is connected to bus B, so as to realize the flexible cross-section access of the power supply control device.
[0041] In some embodiments, the power supply control device further includes a control circuit, and a plurality of switching devices are communicatively connected to the control circuit.
[0042] In this embodiment, the control circuit can be an MCU chip. This control circuit can control the single-sided switch, main switch, bus input switch, bus output switch and tie switch in the switching device to turn off or close, effectively improving the response speed of the power supply control device.
[0043] In some embodiments, the power supply control device further includes multiple detection circuits, the sampling terminals of which are electrically connected to the output terminals of the power supply device, and the multiple detection circuits are communicatively connected to the control circuit.
[0044] In this embodiment, the detection circuit may include at least one of a current sensor, a voltage sensor, and a temperature sensor. The current sensor or voltage sensor may be located at the output terminal of the power supply device or at the lower end of the circuit breaker configured in the power supply device, directly detecting the electrical parameters of the power supply device and feeding them back to the control circuit. The temperature sensor may be installed at key heat-generating parts of the power supply device (such as windings, bearings, heat dissipation systems, etc.), obtaining temperature signals and feeding them back to the control circuit.
[0045] In some embodiments, such as Figure 2 As shown, power supply unit GN+1 serves as a globally shared backup. The control circuit monitors the voltage, current, frequency, temperature, and calculated load rate of each power supply unit in real time through its detection circuits. When the control circuit detects uneven load, it performs calculations using optimization algorithms and drives corresponding single-sided switches (such as single-sided switch DQ12 and other cross-segment tie switches for low-power scheduling) for dynamic fine-tuning. This achieves cross-segment load balancing in the power supply control unit, ensuring that all power supply units operate within an efficient and safe operating range.
[0046] In some examples, such as Figure 2As shown, in the event of a failure in power supply unit G1, power supply unit GN+1 switches power. The control circuit controls the main switch DQ13 to open, achieving electrical hard isolation. Subsequently, it either simultaneously disconnects its output single-sided switch DQ11 and operates or blocks its cross-section interconnection single-sided switch DQ12 according to the electrical connection situation to ensure that the fault point is completely cleared. Then, the backup power supply unit GN+1 is activated, and the control circuit controls the corresponding output main switch DQ(N+1)3 and the necessary single-sided switches DQ(N+1) to close. This power supply unit GN+1 can be flexibly connected to bus A or bus B through its independent single-sided switches.
