关于发电厂厂用电源快切需注意的问题

Concerning on issues in power-supply switching of power plant

结合工作实践及其对厂用电切换的基本要求,探讨了关于发电厂厂用电源快切需注意的几个问题,包括实切过程中安全区域的控制,励磁涌流的抑制及快速切换时间三方面内容,对电厂在切换方式及参数选择上具有一定指导意义。

Combining with working experience and basic requirements of power-supply switching, this article discusses matters needing attention in power-supply switching process of power plant, which includes safe region control in real switching process, excitation inrush current suppression, and quick power-supply-switching time three aspects. Thus, it has certain guiding significance for power plant in switching modes and parameter selection.
