摘　　要：从咸宁电网实际情况出发,提出了110kV微机主变保护整定计算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 Xianning Power Grid, the calculation principles and the methods of solving some special problem in relay protection setting are introduced. Analyze and advance the optimization and predigesting of the setting calculation principle of 110kV microcomputer protection. It would 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 char- acteristic in the setting calculation teach. It takes practical meaning on insure power network operation on the safe side, reduce mistake calculation and boost work efficiency.
