摘要:发电厂的核心就是锅炉的燃烧系统,锅炉的燃烧过程又是一个非常复杂的变化过程,包含很多难以测量的因素控制影响。锅炉存在很多不稳定的因素,一旦受其他因素干扰,就会进入负荷状态。仅仅凭借技术人员很难使锅炉燃烧系统保持在一个稳定的最佳运行状态。70191

Design of Combustion Optimization System for Power Plant
Abstract:Power plant is mainly based on boiler combustion system.Boiler combustion process is a very complex process of change including numbers of factors are difficult to measure the impact.The boiler system is very unstable.Any changes in system load and other disturbances may occur at any time.It is very difficult for technical staffs to kept the boiler burning system in a stable best running condition.
In this paper, an optimization system design idea and two schemes are proposed to optimize the combustion of the power plant. Through the collection of the same data, the design of the algorithm, the overall realization and effect of the system, the results are summarized and analyzed.
The text can be pided into four chapters: The first chapter introduces the development of the combustion system technology of the power plant. Through the summary of the combustion optimization of the power plant, comparing the current combustion optimization of several major optimization techniques in power plants, Summarize the feasibility of the combustion optimization of the power plant and the main problems to be solved; The second chapter is the power plant combustion optimization system ; third chapter, is my optimization system about boiler Combustion Optimization;Chapter four, using the regression equation to calculate the processing data;Chapter five, establishment of Mathematical Model by BP Neural Network Model Forecasting Technique and processing data;Chapter six, comparing the results of both data, discussing the optimization method, summarizing the subject and look forward to development.
Keywords:combustion optimization of power plant;system design; regression curve;BP neural networks ;Matlab
