摘要
针对分布式电源接入会使电网运行方式发生变化,相关备自投配置需要进行改造设计的情况,分析分布式电源对备自投装置及其二次回路的影响,介绍分布式电源单独出线、T接出线2种并网方式相应备自投二次回路的改造设计方案,并说明利用该方案进行改造设计提高了备自投装置的安全可靠性。
In view of the situation that distributed generation is connected in electric power network and busbar automatic trans- fer is reformed, the influence of distributed generation on busbar automatic transfer is introducted. Aiming at multi-terminal lines and single line network synchronization mode of distributed generaror,secondary circuit design and reformation of busbar automatic transfer are analysed and discussed, reformation design is illustrated through this project, in order to ensure the safety and reliabilityof automatic transfer device.
