| Abstract: | The basic principle of dynamic simulation by power system simulation software PSS/E is presented in brief. The HVDC models in PSS/E can be divided into two kinds, in one kind the inductive transient processes in DC transmission line and the dynamic characteristics of the high frequency DC controller are considered, and in the other kind the above mentioned processes and characteristics are not considered. The effectiveness and adaptability of these DC models are analyzed. Finally, the pseudo steady-state HVDC dynamic model CDC4 is studied in detail and is used to simulate the testing system. The simulation results show that the DC model of PSS/E can meet the need of the simulation of large scale AC/DC power systems, so it is available to apply PSS/E to the transient stability analysis of practical large scale AD/DC power system. |
