| 摘 要： | 分布式发电以其能源多样化、环保、节能、高效等多方面的优越性得到越来越广泛的应用.分析了分布式发电(DG)接入配电网后对继电保护的影响及解决措施.重点讨论了10 kV配电网广泛采用的电流保护在接入DG后,DG容量、接入位置对电流保护动作行为的影响,提出了在双侧电源线路上增设断路器、采用方向比较式纵联保护作为主保护、电流保护作为后备保护的保护配置方案,为完善和改进分布式发电的继电保护技术提供一定的参考.

| Abstract: | Distributed generation is widely used for its energy diversification,environmental protection,energy saving and high efficiency.The DG capacity and location influence on current protection action after the connection of DG is analyzed.After the connection of DG,The influence of current protection widely adopted in 10 kV distribution network on DG capacity and location is emphatically discussed.Relay protection that adding circuit breaker to double power line,taking direction comparison pilot protection system as the main protection and the current protection as the back up protection is presented.It provides reference for completing and improving relay protection of DG. |
