摘要
介绍了桐柏抽水蓄能电站一号机在2007年7月中旬三次出现在并网瞬间机端电压偏高且无功瞬时值较高的现象,对此问题进行分析,指出导致异常的4个原因。针对每种可能性均介绍了处理经过并进行了试验,介绍了最终处理措施。介绍了经验。
The phenomenon of abnormal high terminal voltage and instantaneous high reactive power occurred three times in July of 2007 on No. 1 unit of Tongbai Pumped-storage Power Station during instantaneous period of grid connection was presented. Four possible reasons were proposed after analysis, and treatment and test were conducted for each one of them. Finally, the true reason was found out and countermeasures were adopted. Experience from the whole accident was summarized.
