中文摘要：	2015年开启的新一轮电力改革的序幕，明确了我国电改的方向为“放开两头，管住中间”，即放开发电侧和售电侧环节，充分发挥市场在资源配置中的决定性作用，并对中间的输配电环节进行严格监管。电价是电力体制改革的核心，对输配电环节的严格监管，本质上就是对输配电价的严格监管。输配电价制定在我国尚处于起步阶段，未形成成熟的定价机制，急需进行省级电网输配电价定价机制研究。 本文首先对电力行业及电价体系做了简要介绍，从技术特性和经济特性等环节说明输配电价适用于垄断企业的定价方法。然后对垄断企业的定价机制做了分析和梳理，并着重分析了基于回报率管制和基于业绩管制的输配电价定价方法。经过分析，我国目前电网企业输配电价适用于基于回报率的管制方法。接下来分析了我国输配电价定价模型，在基于回报率管制方法的前提下，以准许收入为基础，核定我国电网企业输配电价。并对准许收入的三个构成因素：准许成本，准许收益和价内税金的含义、影响因素和核算方法分别进行了详细研究，包括运行维护费、折旧费、有效资产、准许收益率等关键性参数。然后基于电量传导方式建立了准许收入在各个电压等级的分摊机制，以核算不同电压等级的输配电价。最后以T省电网公司为例，进行了输配电价的算例分析，同时对今后的工作进行了展望。
英文摘要：	The new power reform which started in 2015, clarified that the direction of China's electricity reform is to "open two ends and manage the middle", that is, to develop the power side and power sales side links, and give full play to the decisiveness of the market in resource allocation. Role, and strict supervision of the transmission and distribution links in the middle. Electricity price is the core of the power system reform. The strict supervision of the transmission and distribution link is essentially the strict supervision of the transmission and distribution price. The transmission and distribution price formulation is still in its infancy in China, and there is no mature pricing mechanism. It is urgent to study the pricing mechanism of provincial grid transmission and distribution prices. This paper first gives a brief introduction to the power industry and electricity prices. From the technical characteristics and economic characteristics, the transmission and distribution prices are applicable to the pricing methods of monopoly enterprises. Then it analyzes and sorts out the pricing mechanism of monopoly enterprises, and analyzes the pricing method based on rate of return and performance-based transmission and distribution. After analysis, China's current power grid enterprise transmission and distribution prices are applicable to the return-based control method. Next, it analyzes China's transmission and distribution price pricing model. Based on the premise of the return rate control method, it determines the transmission and distribution price of China's power grid enterprises based on the permitted income. The three components of the permitted income: the permitted cost, the permitted income and the tax within the price, the influencing factors and the accounting methods were studied in detail, including key parameters such as operation and maintenance fees, depreciation expenses, effective assets, and permitted rate of return. Then, based on the electricity conduction method, an allocation mechanism for permitting income at various voltage levels is established to calculate the distribution of different voltage levels. Finally, taking T-Power Grid Corporation as an example, the example of transmission and distribution price was analyzed, and the future work was prospected.
