Abstract

The embodiment of the invention discloses a distributed feeder system and a power distribution system. The distributed feeder system comprises a communication terminal and a distributed terminal, wherein each automatic switch is connected with one distributed terminal; each distributed terminal is connected with one communication terminal; each communication terminal is accessed to a communicationnetwork; the distributed terminals are used for collecting switch information of the automatic switches connected with the distributed terminals; the switch information is sent to other distributed terminals through the communication terminal; and the switch information, which is collected by other distributed terminals, of the automatic switches is received through the communication terminal, the line fault condition is judged according to the collected switch information and the received switch information, and a control instruction is generated to control the automatic switches connected with the distributed terminals. According to the embodiment of the invention, the communication function between the distributed terminals is realized by the communication terminal, the distributed terminals keep the functions except the communication function, the body debugging of the distributed terminals can be separated from the debugging of the communication terminal during debugging, the debugging is simple and flexible, and the power-off debugging is not needed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of power distribution, and in particular to a distributed feeder system and a power distribution system. Background technique [0002] In the field of power distribution technology, the feeder automation in the power grid is divided into fast-acting and slow-acting distributed feeder automation. Compared with the fast-acting distributed feeder automation, the slow-acting distributed feeder automation adopts open-loop operation. Power direction protection is adopted, the fault processing time is relatively sufficient, and the requirements for equipment are relatively low, so it is widely used in distribution network automation. [0003] In feeder automation, distributed terminals mostly use complete sets of equipment. Distributed terminals integrate three remote functions such as voltage and current collection, fault detection, and switch control, as well as functions such as fast co...
