| The traditional power industry consists of generation, transmission, distribution and sale of electricity. It was once thought to be a natural fundamental monopoly industry, so the government controlled it strictly. With the development of researches on scientific technology and electrical network, this traditional view is challenged widely. This paper focused on the key problem in power industry, namely control of power price, and researched the price control theory on the basis of theoretical and demonstration analysis.Firstly, this paper expounded the definition, basic characteristics and boundary of the natural monopoly industries, and made a further analysis of the natural monopoly in the field of power transmission and distribution. Secondly, this paper analyzed the price control in power transmission and distribution, put forward its goal, significance, basic principles and contents. Thirdly, this paper made introduction and analysis about existing models of power transmission and distribution price control, and respective control effects. At last, on the basis of analyzing ROR model and RPI -â…©model, this paper got an synthesized model of price control and excitation model. |
