Online Fault diagnosis and Prediction of Condenser in Nuclear Power Plant

摘要

For helping operators to make appropriate decisions, OFDP based on simulation model is used for condenser. By case analysis, the faults can be diagnosed, and the serious of the accident can be predicted at the same time. In a word, the OFDP can diagnose, verify and predict the condition of the condenser quickly. This methods can help operators and emergency management people in accidents. So, full-scale simulator is used as real system which is different in acquiring data. Lots of further researches should be done, such as handling the simulation errors and decreasing the threshold. In addition, OFDP would play a more important role by combining online monitoring and fault diagnosis. Our future work is of course to research more efficient ways to diagnosis and predict multiple faults, to predict mitigation and operation guidance.
