对于降损增效,很多人都能说出一二。降损是怎样影响购电成本、幅度多大、优化点在哪里?线损率对购电量的影响,恐怕要用数学原理来回答。线损率与购、售电量的关系如下:L%=(Qg-Qs)/Qg×100%所以,Qg=Qs/(1-L%)Qg—购电量,Qs—售电量,L%—线损率假定售电量不变,线损率变化对购电量的影响:趸售企业当前购电量Qg1=Qs/(1-L%)趸售企业线损率降低a%后的购电量Qg2=Qs/(1-L%-a%)
For the reduction of efficiency, many people can say one or two. How to reduce the cost of power purchase, how much, the optimization point where? Line loss on the purchase of electricity, I am afraid to use mathematical principles to answer. The relationship between the line loss rate and the purchase and sale of electricity is as follows: Q% = (Qg-Qs) / Qg × 100% Qg = Qs / (1-L%) Qg- Power Purchase, Qs- Sales, L% Line Losses Assuming the same electricity sales, the impact of changes in line loss rate on electricity purchases: Current purchases by wholesalers Qg1 = Qs / (1-L%) Purchased electricity after sales of wholesalers with a% reduction in line loss Qg2 = Qs / (1-L% -a%)
