The present disclosure relates to the field of power systems, and in particular, to a one-key starting and stopping method and device for a multi-terminal flexible DC power distribution system. The method is used in a central controller, and the method includes: obtaining operation mode parameters, which are used to indicate the operation mode of the multi-terminal flexible DC power distribution system; when receiving a one-key start instruction, according to The operation mode parameters start the multi-terminal flexible DC power distribution system; and / or, when a one-key stop command is received, the multi-terminal flexible DC power distribution system is stopped according to the operation mode parameters. Embodiments of the present disclosure realize automatic control of the multi-terminal flexible DC power distribution system through one-key start and stop commands, ensuring the reliable operation of the multi-terminal flexible DC power distribution system and improving system stability.
Description
technical field [0001] The present disclosure relates to the field of power systems, and in particular to a one-key start-stop method and device for a multi-terminal flexible DC power distribution system. Background technique [0002] The multi-terminal flexible DC power distribution system is a DC-oriented power distribution system. It uses the flexible DC technology of the converter and the characteristics of flexible and controllable power flow to solve the problems of new energy access, DC load efficient power supply, and It provides an effective method for the problem of insufficient reactive power in the load center. [0003] At present, the multi-terminal flexible DC power distribution system is usually controlled to start or stop by manual operation. Since there are many control devices for each converter station in the multi-terminal flexible DC power distribution system, the operating conditions change rapidly, especially when multiple converter stations are invol...
