摘要
从地级电网实际情况出发,介绍整定计算所遵循的原则以及整定计算中所遇到的一些特殊问题的处理办法,分析并提出了110kV微机线路保护的简化原则和优化方案。为继电保护工作者在整定计算环节中通过分析规程并结合保护特性研究简化计算方法提供了策略性的建议,对确保电网运行安全可靠、减少误整定、提高工作效率具有实际意义。
According to the real conditions of area power grid,the calculation principles and the methods of solving some special problems in relay protection setting are introduced.Analyze and advance the optimization and predigesting of the setting calculation principle of 110kV microcomputer protection.It will be a strategic advice for the relay protection operators to predigest the calculation method passing through analysis of the regulations and the study of protection characteristic in the setting calculation teach.It has practical meaning on insureing power network operation on the safe side、reducing mistake calculations and increasing work efficiency.
