Prediction of CCPP output based on improved fuzzy analytical hierarchy process

For the lack of process data of the Gas-Steam combined cycle power plant in initial operating stage, this article presents a method for the output power prediction of CCPP using the Fuzzy Analytical Hierarchy Process (FAHP). Firstly, based on the analysis of the main factors that affect the CCPP output, a hierarchical structure for the prediction of CCPP output is established by combining with Analytical Hierarchy Process and calculating weight vectors according to experts' experience. Then, analyze and correct the operating characteristic curves of CCPP, which will be taken as the input and output membership functions. Finally, the output prediction model can be established, and the effectiveness of output prediction model of CCPP based on improved FAHP is demonstrated by the data set from a real case.
