Research and Application of Data Mining in Power Plant Process Control and Optimization

摘要

As more and more real-time data is sent to databases by DAS, large amounts of data are accumulated in power plants. Abundant knowledge exists in historical data but it is hard to find and summarize this in a traditional way. This paper proposes a method of operation optimization based on data mining in a power plant. The basic structure of the operation optimization based on data mining is established and the improved fuzzy association rule mining is introduced to find the optimization values from the quantitative data in a power plant. Based on the historical data of a 300MW unit, the optimal values of the operating parameters are found by using data mining techniques. The optimal values are provided to guide the operation online and experiment results show that excellent performance is achieved in the power plant.
