| 摘 要： | 随着新能源利用的不断提高,微电网受到了越来越多的关注。在微网孤岛运行结构特点研究基础上,提出了一种基于负序方向元件的微网孤岛运行保护方案。该方案只需比较保护安装处的负序电压与电流的相角差即可判别故障方向,且具有很好的抗过渡电阻能力。基于PSCAD/EMTDC搭建的仿真模型验证了结论的正确性。

| Abstract: | More attention is paid to the micro-grid with the continuous development of new energy utilization.A protection scheme for micro-grid in island operation is proposed based on the negative sequence directional component.This novel protection scheme only needs to compare the phase difference between negative sequence voltage and current in relay location,and it has a good adaptation of fault resistance.The simulation results based on PSCAD/EMT-DC prove the correctness of the conclusions. |
