Abstract


Pumps and fans is extremely broad application in thermal power plants , most of their selection to develop the maximum load that may occur ; usually the case , the unit rarely operate at full capacity , making traffic regulation alone valve or baffle , while the power of the motor is the same, resulting in a great waste ; able to adjust the speed of the motor , according to the actual needs and will greatly reduce unnecessary consumption . Start from the analysis of motor speed , the best choice for squirrel cage motor , frequency control , combined with Hanfeng Power Plant condensate pump and one fan frequency transformation of the actual results of frequency transformation of the process need to be addressed in the remarkable success of the energy saving aspects of the problem and the inverter technology , energy saving for the thermal power plant high-power high-voltage motors , has a certain reference value .
