Master-slave intelligent power distribution automation system

Abstract

The invention discloses a master-slave intelligent power distribution automation system, which belongs to the technical field of electric power. The master-slave intelligent power distribution automation system comprises a power distribution system and a master-slave system, wherein the power distribution system comprises N switching stations connected in series between two transformer substations, and a second circuit breaker of a superior switching station in the N switching stations is connected with a first circuit breaker of a subsequent switching station adjacent to the superior switching station; one switching station between the first switching station and the last switching station is provided with a connection circuit breaker, and the master-slave system comprises intelligent acquisition control terminals configured for incoming and outgoing lines of each switching station and an intelligent control host configured at any switching station. The technical problems of quickly and accurately positioning the fault, limiting the power failure range to the minimum and quickly recovering the power supply of the non-fault area at the downstream of the fault point when various types of fault happen to the power distribution network system can be solved, the operation and maintenance lean level of the power distribution network is improved, the management modernization of the power distribution network is realized, and the power supply reliability requirement of the A+ area is met.

Description

technical field [0001] The invention belongs to the field of electric power technology, in particular to a master-slave intelligent power distribution automation system. Background technique [0002] As the country accelerates the transformation of economic development mode and the adjustment of industrial structure, the load of important users such as high-tech, high-value-added industries, and high-precision manufacturing enterprises is getting heavier, and the quality of life and electrification of residents are getting higher and higher, while the distribution network directly User-oriented, its safety and reliability play a vital role in the development of the national economy. With the development of distribution network topology, the strengthening of power electronic characteristics of the power grid, and the increase of power penetration rate, traditional distribution network protection is facing adaptability problems, and the original protection configuration scheme...
