Abstract: In order to save energy and reduce the house service consumption rate, the condensate pumps of 2×300MW thermal power generation units of Yunnan Huadian Kunming Power Generation Corporation Limited were reformed using variable frequency technology. The modification and perfection of the thermal process control logic and the operational picture in the variable frequency reformation for the condensate pumps were introduced, and concrete requirements for operators were put forward. After the variable frequency reformation of the condensate pumps, the thermal process control logic became perfect and easy to operation, obvious energysaving effects were obtained.

Key words: condensate pump, variable frequency, thermal process control reformation scheme, thermal process control logic, operational picture
