大型火电机组运行优化目标值的研究和确定

Study and determination of operation optimization target values of large size fossil-fired power unit

对火电机组运行优化目标值进行研究,提出对相对独立系统进行优化从而达到整个机组优化的方法,建立了机组主要优化参数的目标函数。该方法在多台大型机组上的应用表明,该火电机组运行优化目标值的确定和计算方法适用于国内同类型机组。

This article studied the operation optimization target values of fossil--fired power unit, putforward the method for carrying out theoptimization of relatively independent system, so as to achieve the optimization of entire unit, and set up the target functions of main opti-mization parameters of unit. The application of this method in several large size units shows that the determination and calculation method ofoperation optimization target values for fossil--fired power units is suitable for the similar type power units at home.
