Abstract: HAPF (high voltage active power filter) and SVG (static var generator), which are specially used for filtering in large-capacity HVDC projects, are configured in the Min-Yue back-to-back HVDC transmission project to meet the filtering requirements and reactive power support on both sides of the converter station respectively. In this paper, according to the characteristics of the Min-Yue project, a complete live commissioning scheme of the HVDC system and a collaborative operation test scheme of HAPF, SVG and HVDC are proposed, which have verified the availability of the equipment and its compatibility with the HVDC system. In view of the SVG fault events in actual operation, the complex problems caused by multiple factors in the process of high voltage transient response of SVG are analyzed in depth, and according to the targeted optimization control strategy, a high voltage/low voltage/three-phase unbalanced transient control test scheme of single SVG equipment is proposed. And a system test scheme is also proposed to verify the overall control strategy of the whole process of SVG and HVDC system under SVG fault. The correctness and effectiveness of the optimization strategy are verified through field implementation.
