IEEE9 Buses System Simulation and Modeling in PSCAD

Based on the IEEE9 buses system provided by the simulation software BPA, the electromagnetic transient model of the 9-bus system in PSCAD/EMTDC is modeled in this paper. The steady-state characteristics and dynamic characteristics of IEEE9 buses system in BPA and PSCAD/EMTDC are compared in this paper. Then, the differences of simulation results between the electromechanical transient model and the electromagnetic transient model are analyzed and the reasons of the difference are figured out in this paper.
