In recent years, China’s cyberspace security is facing increasingly severe challenges. As the national key basic information infrastructure, power control system is very important which is related to the national economy and the people’s livelihood. So network security of power control system should be taken seriously. The network security monitoring capability of power control system has a direct impact on the security of power business such as power production and supply. However, there are few studies on the evaluation of its network security monitoring capability. This paper puts forward the network security monitoring capability evaluation model of power control system based on AHP and fuzzy comprehensive evaluation, according to the research of public network security management capability evaluation, the particularity of network security monitoring system of power control system and the investigation opinions of 20 expert teams in power industry’s network security field. Then, the model is used to evaluate the network security monitoring capability of three municipal power control systems, and the final scores are 93.09, 88.65 and 90.17 respectively. The model established in this paper realizes the quantitative evaluation of the network security monitoring capability of the power control system. And it will help the power company to carry out targeted rectification and improvement according to the calculating result of this model. So the research and application in this paper has a certain practical engineering significance.
