针对火力发电的节能调度,提出按照顶表法安排机组购电顺序,并考虑到机组检修、BOT项目、调峰调频及备用等因素设定火电机组利用小时数,从而改变各机组发电量,实现节能调度。以某具体电网为实例,通过比较不同调度方式下,总的煤耗及污染物排放变化情况,分析并证实了节能调度的节能减排效果。
According to the principles of energy conservation dispatching for thermal power units,an ordered-table was established to determine the order to purchase electricity from thermal power units.What′s more,it was proposed that the unit maintenance,BOT units,units for peak and frequency regulation,and reserving units should be considered to determine the utilization hours of each unit.As a result,the goal of energy conservation dispatching can be achieved.Taking a certain power grid as an example,the effect of energy saving and emission reduction under energy conservation dispatching was analyzed by comparing the total coal consumption and the emission of contaminants under different dispatching methods.
