摘　　要：给出了考虑同时率和负荷率的高峰增量负荷计算模型。为了平缓输配电设备投入的不均匀性对输配电边际成本波动的影响,提出了一种平均增量成本年金计算方法,并建立了能合理分摊电压等级费用基于长期边际成本的计算模型。根据高峰增量负荷及各电压等级所承担的最终平均增量成本,计算得出了分电压等级输配电价。对A地电网长期边际成本进行了实例分析,计算研究结果表明,这种输配电价定价方法能够反映未来经济趋势,同时有利于消除交叉补贴,使各类、各电压等级用户承担的电价更公平、合理。An incremental load model during peak load period in which both load rate and simultaneity of load is given. To mitigate the influence of irregular putting into operation of transmission and distribution equipments on fluctuation of marginal cost of transmission and distribution, a annuity calculation method of average incremental cost is proposed, and a calculation model based on long-term marginal cost, which can rationally share the expense of voltage classes, is built. According to incremental load during peak load period and the final average incremental cost to be borne by different voltage classes, the transmission and distribution prices for different voltage classes are calculated. Case study on long-term marginal cost of a certain regional power network is carried out, and calculation results show that the proposed transmission and distribution pricing method can reflect economic trend in the future and is favorable to eliminate cross-subsidies as well as make the electricity prices borne by various consumers in different voltage classes more fair and reasonable.
