摘要
本文中对220kV枢纽变电所三种主接线方案进行了可靠性计算及分析。方案1(一倍半开关接线,220kV主变通过开关接母线)在保证河北南网220kV系统安全稳定运行方面,尤其在避免系统严重事故发生方面,优于其它两方案,是可靠性较高的方案。
In this Paper, the reliability calculation and analysis are performed for three types of one line diagram of a 220kV hub substation. The first type (1(1/2) Circuit breaker scheme 220kV main transformer
connected via breaker onto the bus) is superior to the other two regarding the stable and safe operation of the Southern Hebei 220kV grid, especially in the aspect of avoiding the occurrence of severe faults of the system It is a scheme with higher reliability.
