In order to improve the economic efficiency of unit 1in 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 conversion control function was added
and a fault situation backup start permit function was set up.The application results show that
after the transformation
the electricity consumption of the feedwater system decreased and the unit operation safety was also improved.
