Research on the Technology and Economic Calculation Model of Power Transmission Line Considering Environmental Benefits.

As an important part of the modern energy supply system, power grid has a very important influence on the regional energy system, especially in the context of large-scale development of new energy sources, cross transmission line planning is the key to optimize the energy supply system. First of all, this paper starts from the typical regional energy problem analysis, proposes the thought of relying on cross transmission to solve the problems of energy supply; Secondly, this paper analyzes the external environment and the effect of cross transmission, establishes the technical and economic model of transmission planning based on cost effectiveness; Finally, according to the example of China's energy system in Beijing, Tianjin, Hebei region, to carry out technical and economic analysis of transmission line technology, and give the relevant recommendations.
