Abstract

Abstract: To study the detail interactions between the AC and DC systems, it is necessary to adopt the electromagnetic transient simulation method. A fast data conversion approach for large-scale AC/DC power systems is presented in this paper, which can convert electromechanical transient simulation models of large-scale AC/DC power systems to the corresponding electromagnetic transient simulation models. Firstly, the large-scale AC/DC power system is reduced in PSS/E; and then the reduced system in PSS/E is quickly converted to the electromagnetic transient simulation models in PSCAD through programming methods; and finally, the detail electromagnetic transient simulation models of the large-scale AC/DC power systems is established. The steady-state verification and transient simulation under 3-phase symmetric faults are done based on the established electromagnetic transient simulation models of a real power system, and the simulation results demonstrate the consistent responses of the simulation models in PSCAD and in PSS/E, which shows that the proposed fast data conversion approach is valid.
