    The parameters configuration of AC filter’s arrester in HVDC project is studied. According to the harmonic frequency of each elements of filter, the paper calculates the maximum continuous operating voltage by harmonic superposition algorithm with a certain margin to determine the filter arresters’ reference voltage. And by establishing the filter’s transient model with PSCAD, the lightning impulse protective level and switching impulse protective level of arresters under switching over-voltage and grounding fault are studied.The technical parameters of arresters can be finally determined.
