摘要
随着超高压电网线路主保护配置的加强,后备保护整定原则具备了简化的基础。针对西北电网的结构、运行特征以及继电保护的配置特点,通过对实际电网保护定值的分析和计算,评价了现有整定原则下后备保护定值的运行性能,提出了西北电网后备保护整定原则的简化方案。应用情况表明,整定原则的简化对电网建设及安全运行有很大的促进和提高。
With the strengthen of the EHV relay configuration, the backup relay setting coordination rules can be simplified. According to characteristics of topology and operation of northwest power grid and protection, relay configuration, a series of calculation and analysis are implemented and the performance of the current backup relay setting is evaluated, then the simplified coordination rules are presented. Application verifies that the rules proposed is effective and feasible.
