摘要
智能变电站设备因其具有信息数字化、功能集成化、结构紧凑化、状态可视化等主要技术特征,对电网运行提出了更高要求。同时,智能变电站的保护因其外回路设计不同、保护装置设计原理的不同对继电保护定值整定也提出了新的要求。结合目前已运行的110k V智能变电站的实际情况,对110k V智能变电站变压器保护定值的整定计算原则进行分析,杜绝继电保护定值误整定事故,确保智能变电站的安全运行。
The equipment of intelligent substations has some main technical characteristics of information digitization, funiction integration, structure compactibility and state visualizationm, so higher requirements are proposed for the retwork running. Meanwhile, the new requirements for different relay protection setting are proposed because of different external- loop design and protection design proinciple of the intelligent substation. Combining actual situation of 110 kV substation at present, analyze the setting calculation principle of the transformer protection setting for 110 kV in telligent substation, elimination accident of the error setting of the. relay prrtection setting, thus ensuring safe operation of intelligent substa- tions.
