    Abstract: The hybrid high voltage direct current (HVDC) technology, integrating the advantages of traditional and flexible DC technology, becomes a kind of new DC transmission technology with more attention. Combined with the conventional and flexible DC systems control characteristic and Based on the conventional DC ABB protection method, this paper proposed several kinds of typical faults control protection strategies for hybrid HVDC and built a typical twin pole hybrid HVDC transmission system model. The simulation verifies the correctness of the protection strategies and the validity controlled by the reactive power control of end convertor station.
    Key words: hybrid high voltage direct current; converter station; control and protection; modeling
