Abstract: Abstract:The problem about high power consumption rate of condensate pumps in power plants of Huadian Power International Corporation Limited was introduced. The statistics of practical power consumption rate of condensate pumps of five classes of power units were given. The reasons of high power consumption rate of the condensate pumps were found. The measures of operation optimization and frequency conversion renovation were adopted, and favorable result was obtained.

Key words: Keywords:condensate pump, power consumption rate, variable frequency speed regulation, optimization reformation
