Abstract

The DC transmission detailed model used in electromechanical transient simulations is studied in this paper. A general mathematical model for both the rectifier and the inverter is established

and the commutation failure criteria are analyzed. Meanwhile

the modeling method for the constant extinction angle control at the inverter side is analyzed in detail. A test system with a detailed model for HVDC transmission is established by electromechanical transient simulation software. In order to study the accuracy of the electromechanical transient model for HVDC transmission

the simulation results of electromechanical transient simulations and electromagnetic transient simulations are compared under faults of different degrees. The comparison results show that the electromechanical transient model for HVDC transmission is ideal and its critical point of commutation failure is different from that of electromagnetic transient simulation. The response waveforms of electromechanical transient simulation basically coincide with those of electromagnetic transient simulation after commutation failures

confirming the effectiveness of the electromechanical transient model for HVDC transmission.
