Abstract: Aiming at the requirement of energysaving and consumption reducing for modern large thermal power units, in the Huadian International Zouxian Power Plant, the variable frequency speed regulation reformation of two condensate pumps of the 1000MW unit was carried out. The control scheme of water level in the deaerator using variable frequency adjustment technology was introduced, and the control of the water level in deaerator was optimized. The reformed system operates reliably; and the energysaving effect of the reformation is obvious.
Key words: 1000MW unit, high-voltage variable frequency technology, energy-saving reformation, condensate pump
