cqvip:In order to effectively imitate the dynamic operation characteristics of the HVDC(high voltage direct current) power transmission system at a real ±500 kV HVDC transmission project,the electro-mechanical-electromagnetic transient hybrid simulation was carried out based on advanced digital power system simulator(ADPSS).In the simulation analysis,the built hybrid model's dynamic response outputs under three different fault conditions are considered,and by comparing with the selected fault recording waveforms,the validities of the simulation waveforms are estimated qualitatively.It can be ascertained that the hybrid simulation model has the ability to describe the HVDC system's dynamic change trends well under some special fault conditions.
