An EMT-DP Hybrid Simulation Method of AC-DC Power System

摘要

In order to take the advantage of electromagnetic transient (EMT) simulation method and dynamic phasors simulation method, a new hybrid simulation of AC-DC system, electromagnetic transient - dynamic phasors hybrid simulation of AC-DC system, where dynamic phasors model and traditional EMT models are applied to build the model of HVDC system and AC system respectively is proposed. The location of the interface, the mutual equivalent method between AC and DC system in the proposed hybrid simulation and the simulation process of the proposed hybrid simulation are investigated. Simulation results show that the proposed electromagnetic transient - dynamic phasors hybrid simulation of AC-DC systems are effective and acceptable.
