安徽220kV电网“六统一”继电保护设备应用研究

摘要

在简要介绍＂六统一＂基本含义基础上,结合安徽电网继电保护运行实际,重点研究＂六统一＂继电保护设备技术原则及配合原则,探讨＂六统一＂推广应用的重点和难点并提出解决策略,研究结果保障了＂六统一＂继电保护设备在安徽电网的推广及应用期间电网的安全稳定运行,具有一定的工程参考价值。%Under the introduction of ″six unification″,considering the operation fact of Anhui electrical power grid,both the technical principle and the matching rule are discussed in detail in this paper.Those problems during the process of popularization and their solutions are also proposed in the paper.Research about ″six unification″ relay protection is beneficial to its application in Anhui power grid and the security of Anhui power grid during the application process,therefore has high engineering practical value.
