摘要

微网故障检测与保护的研究是配电网领域的热点问题。文中首先分析了微网保护面临的主要问题

然后提出了一种新的对含有逆变器分布式电源的微网内部故障的保护方法:实时计算分布式电源等效工频阻抗幅值的变化情况来识别微网内部线路故障;利用不平衡电流来识别微网内部负荷故障;最后基于PSACD/EMTDC搭建的仿真模型验证了新方法的正确性。

Abstract

The detection fault method and protection for micro-grid is a hot issue in distribution system.The major problem that the micro-grid facing is first analyzed. Then

a novel protection method for the micro-grid that includes inverter is first proposed in this paper. The micro-grid line fault can be discriminated by calculating the amplitude of equivalent impedance

and the load fault can be identified by the unbalanced current. At last

the simulation results prove the new method to be reasonable.
