摘要
主要从三个方面对继电保护整定计算工作进行简化:取消零序Ⅰ段、简化零序Ⅳ段计算、统一相间距离保护和接地距离保护。
This paper simplified the setting value calculation of relay protection in the following three aspects : cancel zero sequence zone I, simplify calculation of zero sequence zone Ⅳ and unify phase distance protection with ground distance protection.
