回归分析在小型电厂成本预测和控制中的应用

Application of Regression Analysis to Cost Forecast and Control for a Small Thermal Power Plant

运用逐步回归分析方法对小型电厂进行成本分析，得出影响电厂成本的主要因素是燃料费、辅助材料费及管理费．然后运用多项式回归得出了标准煤耗率与原煤发热量之间的关系，为电厂选择煤质，降低煤耗，控制成本提供了行之有效的方法．

This paper begins with an analysis of the cost of a small thermal power plant by using successive regression analysis. The main factors found out to affect the cost are fuel cost, auxiliary material cost and cost of operation. And the relation is found out between the standard coal cost rate and the caIorific value of raw coal by using polynomial regression, thus furnishing the power plant with an effective method to select raw coal, reduce coal consumption and control cost.
