摘要

针对未来智能配电网提出一种基于通用面向对象变电站事件(GOOSE)的自适应级联方向闭锁保护方案。定义了保护的参考方向整定规则和闭锁方向规则

使保护方案能够根据故障位置自适应改变闭锁方向。利用GOOSE在保护之间交换方向闭锁信号

使得保护之间具有互操作性。新方案具有良好的适应性

能够适应含多微网的闭环或开环运行的配电网

允许配电网工作于孤岛或并网等模式

并能快速切除线路和母线等多种元件故障。在电压互感器断线、断路器失灵以及通信失效等异常情况下

该保护方案仍具有很高可靠性。

Abstract

For the future smart distribution network

a general object-oriented substation event (GOOSE) based adaptive directional interlocking scheme (GADIS) is proposed. By defining the rules for setting reference directions and interlocking directions

the novel protection scheme is enabled to adaptively change the interlocking direction according to the fault position. Furthermore

the interoperability between protections is achieved by exchanging the blocking signals using GOOSE. Well adaptable to both closed loop and open loop distribution networks composed of several microgrids

the proposed scheme functions properly both in the islanded and grid-connected modes of the distribution network and is capable of clearing various component faults such as line fault and bus fault. In cases of voltage transformer breaking

breaker failure and communication failure

the proposed scheme is still reliable. This work is supported by National Key Technologies R&D Program (No. 2013BAA01B04) and National Invention Patent (No. CN103022993A).
