Studying And Development Of Condition Monitoring For Feed-water Pump Of Power Plant

The real-time condition monitoring and trend forecasting of feed water pump are significant for the safety and economic efficiency of improving the operation of power plant. First, this paper introduces the method of on-line performance calculation, then the grey theory is introduced and the GM(1,1) model is emphatically studied. It discusses how to realize the condition prediction of the feed water pump's correlative parameters by using GM(1,1) model. According to the basic simulation results of GM(1,1) model, we analysis its disadvantages and present an improved method, furthermore the method is proved to be effective by simulation. At last, a condition monitoring system for feed water pump is developed by VC based on the above research. It can fulfil the functions of on-line performance calculation, showing the performance curves and real operating points, trend prediction and alarm.
