| Abstract: | The frequency converter speed-regulating technique was used in the frequency control modification on the condensate pump control system of 660 MW subcritical coal-fired power generating units, so as to enable variable-speed operation of motor-driven water pump. Therefore. the deaerator level control system and the realizing scheme for the control and protection logic of two condensate pumps are described and analyzed. It is proved in practice that the energysaving efficiency of Condensate Pump A can be over 15% after the modification and the economic benefits are remarkable. |
