Abstract

The invention relates to the technical field of computer information and the technical field of electrical automation, in particular to a protection constant value intelligent setting system based ona distribution network line. The protection constant value intelligent setting system based on the distribution network line comprises a file processing and importing module, a version library input module, a graph-model integration module, a constant value intelligent setting module and a constant value list management module. According to the invention, efficient, visual and automatic distribution network line multivariable multi-version protection constant value intelligent setting software is provided for relay protection professionals of power enterprises, and the problems of long distribution network line protection constant value setting period, high difficulty, low efficiency and error proneness existing in the relay protection profession at present are solved.

Description

technical field [0001] The present invention relates to the field of computer information technology and the field of electrical automation technology, and more specifically, to an intelligent setting system for protection setting value based on distribution network lines. Background technique [0002] Feeder automatic switch is divided into automatic circuit breaker and automatic load switch. The automatic circuit breaker has a protection configuration, which can realize fault tripping. When the distribution network line fails, the automatic circuit breaker is used to replace the tripping of the substation outlet switch, which can reduce the scope of power failure and improve the reliability of power supply. Although the automatic load switch cannot trip when a fault occurs, it has the functions of voltage closing, non-voltage opening and locking opening and closing. By cooperating with the automatic circuit breaker and automatic load switch tripping, the fault isolation ca...
