Abstract

The invention provides a high-reliability operation mode switching method for a DC power distribution system. First, the operation modes of the DC power distribution system are divided into a three-terminal power supply mode, a double-terminal isolation mode, a double-terminal power supply mode, a single-terminal power supply mode and an STATCOM mode, and then, the system is freely switched amongthe five operation modes according to topological structure changes. By employing the method, rapid and smooth switching of the operation modes of the controllable equipment in the DC power distribution system is achieved so as to meet the current topological structure or operation state of the system, the reliability of power supply to the loads in the DC power distribution system is improved, and long-term stable work of the DC power distribution system is guaranteed.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method for switching a highly reliable operation mode of a DC power distribution system. Background technique [0002] Compared with the concept of AC distribution network, there is also a DC distribution network. The DC distribution network provides the load with the DC bus, and the DC load can be directly powered by the DC bus; while the AC load needs to be powered after passing through the inverter equipment. If the proportion of DC load in the load is large, DC power distribution will have a greater advantage. Compared with the AC distribution network, the DC distribution network has small line loss, high reliability, no need for phase frequency control, and strong ability to accept distributed power sources. [0003] With the widespread application of DC power distribution technology, the research on DC power distribution system has become more and more in-depth....
