摘　　要：In previous papers,the authors presented various electromagnetic transient(EMT)results for multi-infeed configurations focusing on possible effects from failures in one link being transferred to others in terms of induced commutation failures(CF),either during the fault events or after fault clearing in the recovery period.However,the AC system networks in these cases were represented by simplified equivalents.Many interesting conclusions arose from these publications without enabling a much-detailed analysis of overall system effects,which is only possible when the network is modeled in full detail.This paper aims at complementing and comparing simulation results on HVDC multi-infeed configurations using both dynamic stability and electromagnetic transient,while establishing some basic proposals for optimal use of both tools.It identifies the limitations from each type of study so that a comprehensive and useful analysis of HVDC multi-infeed systems can be obtained. 关键词：AC/DC interactions commutation failures HVDC multi-infeed configurations
