摘要
简要介绍传统配电网的3段式电流保护原理,根据配电网网络结构具体分析分布式电源接入导致配电网继电保护误动和拒动的可能,以及分布式电源对重合闸的影响,总结减少分布式电源接入对配电网继电保护影响的主要方法。同时对接入分布式电源后的配电网继电保护提出完善措施和建议。
The paper outlines principle of three-section current protection of traditional distribution system; based on structure of distribution system, it elaborates on possibilities of maloperation and failure to operation in distribution system due to integration of distributed generation, as well as impact of distributed generation integration on switch reclosing. It also summarizes methods for reducing impact of distributed generation inte- gration on relay protection of distribution system ; meanwhile, it presents measures and suggestions to perfect distribution networks after integration of distributed generation.
