Abstract: Primary frequency regulation is the important means to maintain the frequency stability of power systems. Such as large power network, in case of insufficient reserve capacity of frequency regulation, steady state value of frequency deviation can not satisfy the frequency quality .What’s more, sometimes delay of turbo-generator is bigger， the speed of load changing can not be satisfied by primary frequency regulation. So that bigger frequency deviation is produced. In this paper, a case of two areas via a parallel AC-DC links is discussed. Dynamic characteristics are studied on auxiliary primary frequency regulation（APFR） of HVDC. The results show that the speed of primary frequency regulation is increased and dynamic frequency deviation is decreased by APFR.
