为了降低电气化铁路的基本电费,基于牵引负荷实测数据以基本电费最小为原则确定合同年中的约定最大需量,使得按需量计费的年度基本电费最小,与容量计费的年度基本电费相比较,选择合适的计费方式,并采用拟合及BP网络分别估计最大需量,考虑误差偏大,提出以最优加权的组合方法估计最大需量,从而以基本电费最小为原则确定约定最大需量和按需量计费的年度基本电费,其估计结果误差较小,可为电铁用户选择约定最大需量提供参考.
為瞭降低電氣化鐵路的基本電費,基于牽引負荷實測數據以基本電費最小為原則確定閤同年中的約定最大需量,使得按需量計費的年度基本電費最小,與容量計費的年度基本電費相比較,選擇閤適的計費方式,併採用擬閤及BP網絡分彆估計最大需量,攷慮誤差偏大,提齣以最優加權的組閤方法估計最大需量,從而以基本電費最小為原則確定約定最大需量和按需量計費的年度基本電費,其估計結果誤差較小,可為電鐵用戶選擇約定最大需量提供參攷.

To decrease the basic tariff of electric railway, the agreed maximum demand in the contract year is determined by the principle of minimizing the basic tariff based on the measured traction load data so as to minimize the annual basic tariff charged by demand. The annual basic tariff charged by capacity and by demand is compared to select proper way of charge. And the fitting method and BP Network are used to estimate maximum demand separately. Considering of the big error, the combination method of optimal weighting is put forward to estimate maximum demand so as to determine the agreed maximum demand and the annual basic tariff charged by demand by the principle of minimizing the basic tariff. The results show that the error is small enough so that it can be the reference for electric railway users on the selection of agreed maximum demand.
