Anucleolus solution in disconnected local areas for fixed transmission cost allocation of multi-area network;

Research on electromagnetic environment of the next voltage level of transmission system in China;

Voltage levels, transmission, structure and interconnection of synchronized power system;

On the background of \,the problem about power transmission blockade administration is analyzed in five steps-distribution preplan,check blockade adjustment of the preplan,power transmission with extra,turn off.

The paper presents a tentative plan of power transmission pricing mechanism and price structure tor our country based on the principle of best power transmission pricing and through an introduction to and a comparison of the power transmission price structures and transmission pricing mechanisms in some major west countries and regions.

Besides,according to the scheme of the present sets working,we work out the sets working scheme of the next moment on the basis of the rule of the market trade and transmit electricity block management.

The result indicates that the electricity producing companies have strong collusion motivation; and that natural monopoly exists in the electricity transmission market,and new monopoly is easy to form due to the special position of electricity transmission companies.
