摘要

This paper proposes a novel index to quantitatively assess the impact of line commutated converter HVDC (LCC-HVDC) system on short-term voltage stability (STVS) of the receiving-end AC system. The major factor in a LCC-HVDC system to impact STVS is revealed and an analytic method is presented to depict the major factor. On this basis, an assessment index is proposed to quantify the LCC-HVDC system impact on STVS. Compared with short-circuit ratio based indices which only reflect the effects of voltage supporting strength of the receiving-end AC system, the proposed assessment index further takes into account the effects of HVDC system, induction motors, and transmission grid topology: The performance of the proposed assessment index has been validated in a simplified AC/DC system and a real large-scale power system, China Southern Grid.
