Abstract: A Network Distributed High Voltage Direct Current Power Supply Management Method, includes the following steps: multiple high voltage direct current power supply devices are deployed in parallel connected, ensuring that at least one high voltage direct current power supply device not needs to connect with load; there are four power supply modes pre-set in each high voltage direct current power supply device, and the first detection node and the second detection node are set in each device; detect the status of the first detection node and the second detection node, and adopt the predetermined method to change the power supply mode of the high voltage direct current power supply device as per the predetermined condition.

Abstract: A Network Distributed Dynamic Equalized Power Supply Method includes the following steps: multiple High Voltage Direct Current power supply devices deployed in parallel, the entire High Voltage Direct Current power supply devices parallel connected via the Direct Current Power Grid; there being four power supply modes pre-set in each device, the initial setting part being that the power supply mode of back-up High Voltage Direct Current power supply device being mode B, and the rest being mode A, the power supply voltage of the entire High Voltage Direct Current power supply devices to the Direct Current Power Grid being the same. As per the operation status of one certain High Voltage Direct Current power supply device or the change of power supply load, the power supply mode of the High Voltage Direct Current power supply device and the power supply voltage to the Direct Current Power Grid are changed.
