Computer simulation has become an important means of data processing, calculation analysis, online debugging,closed loop control, fault diagnosis, condition forecasting in power system. In order to solve the problem that thereis a lot of power simulation software and users of the software have difficulty in choosing the evaluation index system,this paper studies evaluation indicator system of simulation software based on analytic hierarchy process and providessupport for software selection. Firstly, analyzed and summarized the structure of evaluation index system model whichconsists of 8 indexes, and the indexes were described; Then, create a mathematical model to calculate the weights, includingjudgment matrix, hierarchical ordering, consistency inspection process; Finally, calculate the evaluation index weighaccording to the steps in mathematical model. The results show that posterior simulation function, software maintainability,eigenvalue analysis function, power flow calculation accuracy, these indicators have bigger impact on the power systemsimulation software, when selecting software these indicators should be considered. The content of this paper is thefoundation of system evaluation , and it plays an important role in promoting the informatization level of power system.
