In order to improve the economic efficiency of unit 1 in Wusitai Thermal Power Plant in Inner Mongolia,technical transformation on the feedwater system was carried out.Two of three scoop tube speed-regulating electricicty-driven feedwater pumps were changed into one-to-two frequency variable speed-regulating feedwater pumps.Moreover,the feedwater control logic was optimized,the frequency con-version control function was added,and a fault situation backup start permit function was set up.The appli-cation results show that,after the transformation,the electricity consumption of the feedwater system de-creased and the unit operation safety was also improved.
