| Abstract: | Because of its fast and flexible controllability, the voltage source converter (VSC) based high voltage direct current (VSC-HVDC) will be widely applied in power systems, so it is of practical significance to study the dynamic performance of VSC-HVDC in complicated power grids. The quasi steady state response of flexible HVDC system can be simulated in power system simulation software PSS/E. In this paper the basic principle of dynamic simulation with PSS/E is presented; the effectiveness and adaptability of flexible HVDC power transmission model are analyzed, and on the basis of actual power system the quasi steady-state VSC-HVDC dynamic model VSCDCT is simulated. Simulation results show that it is available to apply PSS/E in transient stability analysis of practical large-scale AD/DC power system. |
