Analysis on Condensate Pump HV Frequency Inverter Retrofitting & its Practice

The two driven by one frequency conversion is conducted on condensate pump in certain power plant.Practice at site has made for improving effective work duration of inverter,realizing the automatic control of water level,harmonic operation between condensate water pump speed regulation deaerator water level regulator valves.Reasonable commissioning policy of inverter has been determined,auxiliary power has been reduced effectively.
