摘要
为了进一步提升配电网继电保护水平,要结合其实际特性,充分分析分布式光伏电源对其产生的影响,以便落实更加可控的资源处理控制模式,在维持应用效能的同时,为配电网运行质量全面优化提供保障,实现经济效益和安全效益和谐统一的目标.简要分析了光伏电池输出特性和自适应电流速断保护,着重讨论了分布式光伏电源对配电网保护产生的影响,针对具体工作提出了相应建议.
In order to further improve the relay protection level of distribution network,it is necessary to fully analyze the influence of distributed photovoltaic power supply on it in combination with its actual characteristics,so as to implement a more controllable control mode of resource treatment,ensure the overall optimization of distribution network operation quality while maintaining application efficiency,and achieve the goal of harmonious unification of economic benefits and safety benefits.This paper briefly analyzes the output characteristics of photovoltaic cells and adaptive current quick-break protection,emphatically discusses the influence of distributed photovoltaic power supply on distribution network protection,and puts forward some corresponding suggestions for specific work.
