摘要
深圳前湾LNG电厂9F级天然气-蒸汽联合循环机组为引进型的新机组,在国内刚投入使用,其特性并不被完全熟知。为此,结合该电厂的电气接线和静态频率转换装置(static frequency converter,SFC)的启动特点以及现场试验实测数据,对一起发生在该机组发电机出口电磁式电压互感器(TV)的铁磁谐振事故进行分析,并提出解决方案,最后问题得到圆满解决。
The 9F class gas-steam combined cycle unit is imported-type unit newly put into use in China, whose characteristics are not well known yet. Combined with the electric connection and the SFC （static frequency converter） startup characteristics as well as the data obtained in field testing in Shenzhen Qianwan LNG Power Plant, this paper analyzes a ferroresonance accident in generator outlet electromagnetic voltage transformer of the unit, and presents a solution thereto. The problem has been solved successfully.
