摘要
阐述了配电系统保护自动化的主要功能和作用,以及与之有关的两种运行方式—美英式和日本式,分析了智能化高压开关诸如机电一体重合器和分段器等作用和条件,结合国内电网运行实际,提出了若干配合原则、配合要求和配合实例。
The principal function and effect of automatic protection of distribution system and the related two operating modes such as American-Britain mode and Japanese mode are described. The characteristic function and restrictive condition of the intelligent HV switches such as the mechatronic rccloser and sectionalizer etc. are analysed. Then in view of the practice in domestic electric power network operation, the principle and requirement of the configuration are suggested. The cases and problems existing in the automatic protection of distribution system are investigated and the methods and direction for the performance of DA engineering are indicated.
