摘要
3/2接线方式的复杂性主要体现在断路器继电保护及自动装置的配合上。介绍了3/2接线特殊运行方式下线变串开关自动重合闸与保护配合的情况。并以"N-1"原则为指导,分析了特殊运行方式事故情况下,继电保护和自动重合闸装置的动作过程及其对主设备和系统的影响,提出了重合闸方式应根据系统结构和现场运行条件转换的方案。
The complexity of 3/2 connection manifests in the coordination of relay protection with automatic device. This paper introduces the coordination of automatic reclosing of circuit breaker in line-transformer strings with 3/2 connection and the relay protection. Based on the principle of N-1, the paper analyzes the action process between the relay protection and automatic reclosing with 3/2 connection by the accident time as well as its affection on the main equipment and system, and proposes the scheme to convert the mode of the automatic reclosing according to system structure and fieht operation condition.
