火电厂电机变频装置旁路方式的选择

Selection of bypass mode for the motor frequency converter of thermal power plants

介绍了火电厂辅助电机变频器不同旁路切换方式的动作过程,分析了自动和手动2种旁路切换方式对水泵电机变频器和风机电机变频器运行工况的影响,可供其他电厂进行电机变频调速改造时参考。

The movement process of different bypass switchover modes for auxiliary motor frequency converter of thermal power plant were introduced,it was analyzed that the influences on operating conditions of pump motor frequency converter and fan motor frequency converter by automatic and manual bypass switchover modes,which can be for a reference when other power plants transform motor frequency control.
