世界电力的生产,尤其是一些工业发达的国家中正在迅速增长,根据目前的统计,世界上对电力的需要量是每十年增加一倍,就是每年新增加7.2%的装机容量,其中包括旧机组的更换。显然,这种情况越来越要求更大容量的机组,同时也要求新机组的建设速度快和经济性好(重量轻、价格低、占地面积少和其它指标)。同时新机组在电网中的调节问题也很重要,新机组的容量最好是电网总装机容量的4～7%。 The world’s electricity production is growing rapidly, especially in some industrialized countries. According to the current statistics, the world’s demand for electricity is doubled every ten years, that is, an additional 7.2% of installed capacity is added each year, including the old Unit replacement. Obviously, this situation is increasingly requiring larger capacity units, while also requiring new units to be constructed quickly and economically (light weight, low price, small footprint, and other indicators). At the same time, the adjustment of new units in the power grid is also very important. The capacity of the new units is preferably 4 to 7% of the total installed capacity of the power grid.
