变电站用低压交流环网故障的危害
Fault Hazard of Substation Low-voltage AC Ring Network
摘要
Abstract
This paper studies various faults of ring network of the substation low-voltage AC system (hereinafter referred as system) and analyzes characteristic quantity of the system as well as action situation of relay protection equipment and automatic transfer switching equipment (ATS).It finally draws conclusions that fault types of the ring network directly affecting the system can cause relay protection operation immediately while those fault types indirectly affecting the system will cause relay protection maloperation and expand influencing range of faults, and faults of multi-phase ring network may cause abnormal switch of ATS.It proposes to study methods for exploring faults of AC ring networks.关键词
