摘要
发电厂厂用电工作电源与备用电源属于同一个大电网系统,在一些特殊情况下,两者之间也会有大的功角,导致厂用电切换无法采用并联方式。针对上述问题,结合上安#5机组启动试验,对同系统厂用电大功角切换问题进行了探讨,纠正了某些厂用电切换的不正确观点,提出了合理的切换方式,并经过试验验证其合理性。
Abstracts Plant power supply and standby power supply of power plant belong to the same power grid system, bigger power angle between them may induce that power supply transfer of power plant can not adopt parallel connection in some special conditions. For the problem above,based on start-up test of Huaneng Shang＇an power plant, this paper discusses the problem of the same power grid system＇ s power supply transfer in big power angle, and rectifies some inaccurate viewpoints on power supply transfer. It puts forward an appropriate power supply transfer mode, and testifies the rationality of this mode by test.
