摘要
三峡左岸电站由于装机容量巨大,500 kV系统发生故障时的非周期分量将对母线保护生产极为不利的影响,母线保护的选型必须考虑防止电流互感器饱和而导致的误动及500 kV母线电流互感器变化不一致等方面的问题。
The installed capacity of generators in Three Gorges Project Left Bank Powerhouse is very largeso the acylic component caused by the short circuit faults will make a very bad influence to busbar protection.Based on this casethe issues such as the maloperation of busbar protection caused by saturated CT and ratio difference current of transformer of busbar CTshould be considered when making the selection for busbar protection.
