摘要(Abstract)：

为了降低发电厂的厂用电率,实现节能减排,大容量电机的变频运行是首选措施之一。介绍了超超临界1 000 MW发电机组配置的凝结水泵及其高压变频器和相关配套设备的计算与选型,提出了高压变频器选型中应注意的问题。
Inversion operation of large-capacity motors is one of the first choices as a measure to reduce the auxiliary power ratio in power plants and realize energy saving and emission reduction.The paper describes the calculation and type selection for the condensate pump,high voltage inverter and the supporting facilities for the 1 000 MW units and presents the considerations for type selectlon of high voltage inverters.
