摘要
从西北电网750 kV示范工程试验系统入手,认真分析、研究、计算、校核了750 kV系统零起升流、升压试验时是否会发生自励磁现象、试验系统各变压器分接头位置能否满足各级电压运行的要求,提出零起升流、升压试验方案。针对试验方案,做出相应的事故预想,最后给出试验结果。
Based on the experimental system of 750kV demonstration project in northwest power grid of China, the self-excitation phenomenon at starting procedure and the location of transformer taps are studied. The selection of transformer taps must meet the need of different voltage levels. According to the study, the experiment schemes of voltage and current rising from zero are proposed. The accident prospecting is put forward on the experiment schemes. The experiment results are also presented.
