| 摘 要： | 传统的放射状链式配电网接入分布式发电系统后,配电网继电保护及安全自动装置的配置和整定变得非常复杂和困难。详细分析了分布式电源的接入对原有的配电网继电保护和安全自动装置运行的影响,提出了一种在分布式电源并网时的保护及自动装置配置方案,该方案将配电网原有的距离保护改造为允许式方向纵联保护,提高了并网变电站的供电可靠性,具有实际可行性。

| Abstract: | After the distributed generation connected to the traditional radial distribution system ,the configuration and setting of relay protection and safety automatic devices become very complicated and difficult. The impact of distributed generation to the running of primal relay protection and automatic devices of distribution system is discussed in detail in this paper, a configuration of relay protection and safety automatic devices for the distributed generation connected to the electrical system is proposed, it has high reliability and practical feasibility by turning the primal distance protection into permissive pilot direction protection. |
