Power system of energy conservation and emissions reduction for promoting China's overall energy conservation and emissions reduction strategy is of great significance. As an important part of the thermal power plant circulating water system, its optimal operation is very important for the safe and economic operation of the whole unit. This paper combining the reality of Shanghai that wujing second power generation co., LTD., according to the principle of high voltage variable frequency speed regulation and high voltage variable frequency speed regulation system operating experience at home and abroad for reference, and for the company's circulating water pump in the high voltage frequency conversion transformation, improved the circulating water system operation mode, improve the level of automation. Optimize the corresponding circulating water system, to improve the starting characteristics of circulating water pump, improve the reliability of the operation. Section by energy, a comprehensive analysis to evaluate the effect after transforming circulating water pump frequency conversion, confirmed the advantages of high voltage variable frequency speed control technology. Paper work for application of high voltage variable frequency speed regulation technology in power generation enterprises has a strong reference.
