Abstract:

In the condensate system, in order to reduce the throttle loss of the deaerator water level control valve and reduce the power consumption rate of the condensate pump, by means of test and grope, the variable frequency operation mode of the condensate pump was optimized. When the unit operates normally, the condensate pump converter can be put into operation automatically, the safe and stable operation of the unit under various conditions was ensured, and the power consumption rate of the condensate system was reduced further.

Key words: power plant, condensate pump, variable frequency operation mode, optimization, energy conservation
