继电保护与配电自动化配合的配电网故障处理
Relay protection and distribution automation based fault allocation and restoration for distribution systems
摘要
Abstract
To coordinate the relay protection with the distribution automation system (DAS), the probability and strategy of multi-grade protection are discussed. For time-grading cooperation depending on time delay, the approaches are divided into two classes according to different operation mechanisms, driving technology and fault detection algorithms. The centralized fault allocation and restoration modes based on relay protection and distribution automation are discussed. The setting principles of two-grade time-grading protection and three-grade time-grading protection are suggested. The hybrid approach of multi-grade protection and distribution automation system for centralized fault allocation and restoration is proposed. The way to combine multi-grade protection with voltage-time type feeder automation is suggested, which can avoid the whole feeder outage due to any fault on a branch. Examples are given to explain the proposed ideas.关键词
