The Technology for Selective Coordination of Multilevel Protection in Intelligent Power Distribution System
摘要
Abstract
Smart grid is the future development direction of the electric industry. The reliability and continuity of the power supply is particularly concerned by people. Multilevel protection in intelligent power distribution is critical. The conventional method for short circuit fault in low-voltage system is over-current protection. But it has disadvantages such as inadequate of speed and reliability and inadequate of the ability to coordinate at each level etc. In order to research the mechanism of the full range of selective coordination of multi-level protection and improve the existing lack of selective protection, based on the review of applied research of selective protection methods of short-circuit fault in recent years, the paper proposed the experimental system and control and test device technology solution of multi-level selective short-circuit fault protection, and provide an experimental basis for research of low-voltage multi-level selective coordination protection.关键词
