Abstract: The twospeed reformation and the operation situation of the water circulating pump of 630MW supercritical unit in Jiangsu Guoxin Yangzhou Power Generation Corporation Limited were introduced. After the reformation, the water flow can be adjusted by changing the motor speed in accordance with the season variation. The service power rate was reduced, and the obvious economic benefit was obtained.

Key words: water circulating pump, two-speed motor, energy-saving reformation
