Correlation Analysis of Operation Data and Its Application in Operation Optimization in Power Plant

The equipments in power plant are closely related and interacted, and the relationships among the equipments are manifested by operation data. According to the actual operation data, the potential associations can be found and applied to guide the operation optimization in power plant. The characteristics of operation data and the methods of correlation analysis were discussed in detail to estimate the related degree between operation parameters. The correlation analysis and correlation computing method of operation data were proposed. Based on the correlation of operation data, the fuzzy association rule mining was introduce to find the operation optimization values to guide the operation in power plants. The optimal excess air coefficients is obtained and the regression equation is established, which can be provided to optimize the operation. It is benefit for guiding the operation optimization and economical operation in power plant.
