摘要:
针对含有分布式电源的小电阻接地方式配电网建立了小电阻接地故障分析模型,通过对线路故障点零序导纳的提取,说明了零序导纳法的应用流程和原理.根据分布式电源接入系统的变压器接线形式不同,分析了主要接线形式下的配电网零序网络.根据所提的方法说明了故障定位的流程.最后利用仿真分析验证了所提方法的有效性,并为含有分布式电源的小电阻接地方式的继电保护配置提供了参考.
Abstract:
A low- resistance ground fault analysis model for low-resistance grounding distribution networks containing distributed power sources is established．The application flow and principle of zerosequenc admittance method are explained through the extraction of zero-sequence admittance at fault points．According to the different wiring forms of the transformer in the distributed power connection system , the zero sequence network of the distribution network under the main wiring form is analyzed．According to the method proposed , the fault location process is explained．Finally , simulation analysis is used to verify the effectiveness of the method proposed , and provide a corresponding reference for the configuration of relay protection with distributed power sources with low resistance grounding．
