Establishment on Evaluation Indicator System for Power System Simulation Software

ABSTRACT

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 there is 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 provides support for software selection. Firstly, analyzed and summarized the structure of evaluation index system model which consists of 8 indexes, and the indexes were described; Then, create a mathematical model to calculate the weights, including judgment matrix, hierarchical ordering, consistency inspection process; Finally, calculate the evaluation index weigh according 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 system simulation software, when selecting software these indicators should be considered. The content of this paper is the foundation of system evaluation , and it plays an important role in promoting the informatization level of power system.
