In order to overcome the problem of low accuracy of operation and maintenance risk assessment of power grid communication network, this paper proposes a method of operation and maintenance management risk assessment of power communication network based on DEMATEL. Based on the analysis of DEMATEL's power communication network pedigree, the assessment index system is divided into three first-class indexes: common business support, normal operation of communication network and operation and maintenance quality. The analytic hierarchy process (AHP) is introduced to calculate the risk value of operation and maintenance management of power communication network. The experimental results show that the accuracy of risk assessment method is close to 100%, and the failure rate is less than 3%, which improves the early warning rate. The accuracy of risk assessment, risk assessment rate and early warning rate of operation and maintenance management of power communication network have been improved.
