| Abstract: | The operation of the condensate pump used in 300 MW unit with its speed controlled by variable frequency has been presented in the article after transform from the fixed speed condensate pump.The operation mode and the result of energy conservation of the condensate pump have also been described in the article after transform from the fixed speed pump into the controlled speed pump with variable frequency.The condensate pump with variable speed will be operated within a rated rotating speed based on an installed frequency converter and controlling rotating speed of the pump and determining the logic parameters of frequency control so as to reduce the vibration of the condensate tubes and make the operation more reliable. |
