摘要
将不同品质的煤配制成与锅炉设计煤种相近的混煤,是目前发电厂普遍采用的一种方法,为了更好地选择配煤方案,降低购煤成本,需要对煤的未来价格进行预测。灰色预测法和时间序列法是常用的预测方法,综合采用这两种方法对煤的价格进行预测,将预测的价格作为评选配煤方案的一个重要属性,为发电厂煤炭采购决策提供了新的方法。
The method,to blending different quality′s coal into the blended coal that is similar to the designed coal of boiler,was generally applied in the generation company.In order to select the optimal blending options and to reduce the cost of coal,the future price of coal was needed to be forecasted.Grey forecasting and time series forecasting methods are commonly choices.The price of coal was forecasted by combining both methods,and the future price of coal was an important evaluation attribute of the coal blending programs,which provided a new method for the power plant coal purchase decision-making.
