智能化高压电器与配电网保护自动化

Intelligent HV Apparatus and Distribution Automatic Protection

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的作用及运行条件 ,并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 pricipal function and effect of automatic protection of distribation system and the related two operating modes such as American Britain mode and Japanese mode are destribed. The characteristic function and restrictive condition of the intelligent HV switches such as the mechatronic recloser and sectionalizer etc. are analysed. Then in view of the pratice 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.
