200MW机组高压厂用电切换问题探讨

Discussion of the Changeover Problems of 200 MW Power Station Service

２００ Ｍ Ｗ 机组高压厂用电自动切换存在的问题较多，导致厂用电事故扩大。传统的 Ｂ Ｚ Ｔ 多不能适应大容量机组厂用电切换。从对发电设备安全、可靠、稳定运行的观点出发，分析了高压厂用电自动切换采用传统的 Ｂ Ｚ Ｔ 所存在的问题，提出了相应的解决方法，并加以探讨。

There are problems in automatic power changeover of HV station service that extends the power incident.The traditional BSZ device is not suited for changing over the station service in large capacity power station.From the point of view of soft,reliable and stable operation,the problems are analyzed and the suggested solutions are proposed.
