摘要
介绍了几种馈线自动化实现模式的工作原理及优缺点。针对其存在的过分依赖通信网络、不能一次性实现故障的切除与隔离以及分支线故障造成全线的短时停电等问题,提出了三级级差保护与电压时间型分段器及集中式故障处理的配合实现的馈线自动化新模式,并分析了方案的可行性与实现方法。
This paper introduces the operating principle, advantages and disadvantages of several automatic realization mode of feeder. Aiming at the problems, such as over - dependence on communication network, failure of fault elimination and insulation at the first time and short - time whole line outage caused by branch line fault, the paper also proposes the new automatic mode of feeder which adopts the cooperation of three - stage - difference protection and voltage - time type of sectionalizer to deal with fault, and analyzes the feasibility and realization of the plan.
