Abstract

Abstract: In recent years, the condensate pump improvement with high-voltage frequency conversion technology has been in fast-growing, and the new technology of permanent magnetic speeding is getting increased attention. In this paper, the comparative study on the effects of condensate pump improvement with permanent magnet speeding and high-voltage frequency conversion technologies is conducted to provide a reference for technical selection in the large condensate pump improvement. According to the practical operation and research, two power plants with units of similar unit type, capacity and operational lifespan are selected to analyze the energy saving effects, economic performance, reliabilities and investment benefits of the improvement. The study concludes that in the improvement of large condensate pumps, the permanent magnetic speeding technology outperforms the high-voltage frequency conversion technology in terms of reliability, while in the aspects of energy saving and investment benefits, the latter one outgoes the former one.

Key words: thermal power plant, condensate water pump, permanent magnet speeding, high voltage inverter, energy saving
