Fault diagnosis and performance supervision of condenser based on fuzzy neural network

TENG Pi-zhong1,ZHANG Pin2,CHEN Rong-sheng 3,CHEN Qun2, SHI Yong-heng1,YU Bao-ning 2,YANG Ya-ping 1(1.Southeast University,Nanjing 210096,China;2.Fujian Yongan Power Plant, Yongan 364013,China;3.Quanzhou Power School,Quanzhou 364000,China)  
Condenser is the primarily auxiliary equipment of condensing turbine,and relations between condenser system operation faults and their symptoms are nonlinear,complicated,fuzzy and random,which are difficult to be represented by math equations.Combining advantages of fuzzy theory and neural network,a serial fuzzy neural network is presented as condenser fault diagnosis model and the relevant software of fault diagnosis and performance supervision is developed with Matlab 6.5.The fault diagnosis software includes symptom parameter derivation,fault diagnosis and result display.The performance supervision software is used to calculate relevant parameters and compare changed operation state with normal one.An actual example of a 100 MW steam generation unit is given.
