在现行的相关规范和标准下,母线保护装置运用于旁路代路方式时存在拒动和误动的隐患。论文深入分析了旁路在不同代路运行方式下母线保护的电流计算、逻辑判断以及开入和开出情况,并给出了相应的回路改进方案,且对旁路代路运行方式的软件程序设计提供了思路,为旁路代路下母线保护的安全稳定运行增加了一道保障。
Under the current relevant codes and standards
there are hidden dangers of misoperation when busbar protection device is used in bypass switching mode. The current calculation
logic judgment
input and output of busbar protection under different bypass operation modes are analyzed. At the same time
the corresponding circuit improvement scheme is given
and the idea of software program design of bypass operation mode is proposed
which provides a guarantee for the safe and stable operation of busbar protection under bypass switching mode.
