Reactive compensation and alternating current filtering system applied to high-voltage direct current transmission

The invention discloses a reactive compensation and alternating current filtering device system applied to high-voltage direct current transmission, which can effectively improve the reactive compensation and alternating current filtering performance of a converter station through active and passive reactive compensation and alternating current filtering equipment reasonably arranged on a converter transformer valve side and a network side. The harmonic current of the converter transformer and the adjusting frequency of the tap switch are greatly reduced, the overall performance of converter station equipment is improved, the occupied area of the converter station is reduced, and the traditional high-voltage direct-current transmission technology can better adapt to a novel electric power system environment. 本发明公开了一种应用于高压直流输电的无功补偿与交流滤波装置系统，通过合理布置在换流变阀侧和网侧的有源与无源的无功补偿及交流滤波设备，可以有效改善换流站的无功补偿和交流滤波性能，大大减小换流变的谐波电流和分接开关调节次数，提高换流站设备的整体性能，减小换流站占地面积，使传统高压直流输电技术更好地适应新型电力系统环境。
