广州地区110kV微机线路保护整定计算原则的修正和简化

Modifying and Predigesting of the Setting Calculation Principle of 110kV Microcomputer Line Protection in Guangzhou Area

针对广州电网实际情况,对110kV微机线路保护的部分整定计算原则进行了修正和简化,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,提高工作效率提供了策略性建议。

Aiming at practicaI situation in Guangzhou power network, the author modified and predigested a part ol the setting calculation principle of l lOkV microcomputer Iine 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 characteristic in the .setting calculation tache and to boost work efficiency.
