分布式发电对配电网继电保护的影响研究

Research on the Impact of Distributed Generation on Relay Protection in Distribution Networks

新能源发电逐渐取代传统能源发电已经成为我国电力产业一大发展趋势。为了能够缓解能源紧张、减少有毒有害气体排放,新能源发电技术的应用愈加广泛,分布式发电技术也应运而生。虽然分布式发电技术推动了电力产业变革进程,但也给电力系统运行控制造成巨大影响,特别是配电网继电保护方面。传统配电网保护策略已经无法适用于分布式发电并网模式,必须要对配电网保护进行改进和调整。基于此,分析了分布式发电的含义,探究分布式发电对配电网继电保护的影响,并有针对性地提出几点解决对策,旨在降低分布式发电对配电网继电保护的负面影响。

The gradual replacement of traditional energy power generation by new energy power generation has become a major development trend in China's power industry.In order to alleviate energy shortages and reduce toxic and harmful gas emissions,the application of new energy power generation technology is becoming increasingly widespread,and Distributed Generation technology has also emerged.Although Distributed Generation technology has promoted the transformation process of the power industry,it has also had a huge impact on the operation and control of the power system,especially in the field of distribution network relay protection.The traditional distribution network protection strategy is no longer applicable to the distributed generation grid connection mode,and it is necessary to improve and adjust the distribution network protection.Based on this,the meaning of distributed generation is analyzed,and the impact of distributed generation on distribution network relay protection is explored.Several targeted solutions are proposed to reduce the negative impact of distributed generation on distribution network relay protection.
