【 摘 要 】

Power industry is the basic industry of China's national economy. Power grid construction is a basic construction related to the national economy and the people's livelihood. It has many characteristics, such as large investment, many participants and complex organizational relationship. There are many risks in the process of construction. In addition, with the development of economy, the risk of power grid planning is more and more complex. In order to improve the scientificity of urban power network planning, it is very important to evaluate its risk scientifically. Considering the characteristics of power grid projects and analyzing the shortcomings of past grid project risk assessment methods, this paper proposed a risk assessment model based on matter-element model and extension analysis theory. This model introduces the correlation function and the degree of association in the extension set, which can easily quantify the qualitative indicators. In this paper, an empirical analysis of a city power grid planning in China has been carried out. The results show that the method has strong feasibility and practicability.
