摘要
电量的安全稳定供给是铝厂氧化铝电解的一个最重要的环节,而年供电量系统具有灰色系统的特征。通过收集整理近几年焦作金冠电厂对万方铝厂的年供电量数据,采用灰色系统理论建立GM(1,1)模型,对2008年金冠电厂对万方铝厂的年供电量进行预测,关联度达到了0.8,说明预测值准确可靠。对指导万方铝厂原材料的购进量和铝锭的年产量有一定的实际指导意义。
The safe and stable annual power delivery is important in alumiraun oxide electrolysis of aluminum manufacturer. The annual power delivery system bears characteristics of grey system. This paper collects the annual power consumption data of Jin Guan Power Plant to Wanfang Aluminum Manufacturer and sets up GM（1,1） modal by using grey system theory, to forecast the 2008 electricity delivery of the plant. The relative degree can reach 0.8, indicating that the forecast is correct and reliable, significant to guide the quantity purchased and the aluminum in got out put of Wanfang Aluminum Manufacturer.
