Abstract:

In order to improve the accuracy of the traditional simulation model of HVDC (High-Voltage Direct Cur-rent Transmission)system,a novel hybrid-model simulation algorithm is proposed to analyze the transient stability of AC/DC system,in which the dynamic phasor theory and the traditional electro-mechanical transient models are respectively applied to the modeling of HVDC and AC systems.An iterative algorithm for the interface between the HVDC dynamic phasor model and the AC system is then investigated by hybrid simulation.It is then concluded that,as compared with the electromagnetic transient model,the HVDC dynamic phasor model is of higher accura-cy,and that the proposed interface algorithm can be effectively adopted to analyze the transient stability of AC/DC system.

Key words: hybrid simulation, dynamic phasor, transient stability, High-Voltage Direct Current Transmission
