摘要
针对分布式电源广泛接入对配电网保护系统带来的适应性挑战,分析了传统保护配置失效的机理,构建了分层保护架构,提出了动态整定与容错调度控制策略,阐述了复合判据在故障识别中的应用,介绍了保护系统的通信协同机制。结合典型节点故障场景进行仿真建模与响应分析,结果表明该策略在故障识别准确性、动作时效性与系统鲁棒性方面均有显著提升。
Given the adaptability challenges posed by the widespread integration of distributed generation to the distribution network protection system,this paper analyzes the mechanisms behind the failure of traditional protection configurations,constructs a hierarchical protection architecture.The paper proposes dynamic setting and fault-tolerant scheduling control strategies,elaborates on the application of composite criteria in fault identification,and introduces the communication coordination mechanism of the protection system.Through simulation modeling and response analysis based on typical node-fault scenarios,the proposed strategy significantly improves fault-identification accuracy,action timeliness,and system robustness.
