The Research On Operation Performance Appraisal System Of Large-Scale Thermal Power Plant

Under the circumstance of electric net enterprise being separated from power plant, large-scale thermal power plants take to market and canonical run step by step. They demand themselves to excavate the internal potential sufficiently, handle scientific management and pay attention to producing result, in order to make generating units operate at the best way and realize the target of saving energy, reducing consumption and cost.Many thermal power plants improve the operating effect of generating units by the different methods, such as the technical transformation, the units optimizing controlling and building various levels information systems, but their economy and security are still under the influence of operation parameters. Practice indicates: The control levels of operation personnel have very big effect on operation parameters. On the other hand, operation parameters are real-time stored in database and become a "data mine" that including all the producing process. Therefore, making use of these real-time parameters to appraise operation personnel becomes an important job for thermal power plant.This article unifies the performance appraisal theory and the operation personnel post characteristic, and has established the large-scale thermal power plant operation performance appraisal system structure, that is, the goal and principle of performance appraisal, the appraisal index and weight, the appraisal index standard and appraisal implementing. Firstly, according to performance appraisal theory, it conform the goal of performance appraisal for operation personnel and the particular design principle. Secondly, on the basis of analyzing the source of appraisal index, it ascertains concrete appraisal index by Delphi method and weight by Fuzzy AHP method. Thirdly, it analyzes the association of DCS data and discusses the thought and standard of performance appraisal index on Multi-dimensional Association Rule. At last, according to information system developing method, it analyzes and designs relevant operation performance appraisal information system to realize the appraisal of operation personnel.Operation performance appraisal system combine management theory with mathematics method and information system development, and make the information system have feasible management, scientific method and advanced technology, which is an effective approach to improve economic efficiency of thermal power plant.
