To enhance the scientificity of urban power network planning, it is necessary to identify and evaluate the risks in urban power network. In this paper, a questionnaire of urban power network concerning the risks in domestic urban power network is designed; then based on fuzzy membership theory the possibility of occurring risk in different stages, i.e., planning stage, feasibility study stage, construction stage and operation stage, etc., and the extent of damage are quantized; and then the comprehensive quantization score of each risk are given; finally, the key risks, which special attention should paid to in planning, construction and operation stages of urban power network, are summarized. The proposed method could offer decision base to evade risks in different stages of urban power network.
