特高压直流换流站交流滤波器场布置研究

交流滤波器及并联电容器是特高压直流换流站不可缺少的重要组成部分。合理布置交流滤波器场,尤其是交流滤波器大组配电装置,对控制特高压换流站总平面占地及工程造价有决定性的作用。通过对交流滤波器大组田字形及其2种改进布置方案进行技术、经济比较,得出：优化方案A占地较少,适应性最强,宜推荐采用;优化方案B占地最省,费用最低,但适应性较差,在不便采用单柱式隔离开关的地区可采用。

Study on Layout of AC Filter Switchyard of UHVDC Converter Station

AC filters and shunt capacitors are important and indispensable parts of UHVDC converter stations. Rational layout of AC filter switchyard, especially AC filter bank switchyard, plays a decisive role in controlling the total land area and project cost of UHVDC converter station. Technical and economic comparison is made on the traditional crisscross shaped AC filter layout and its two improved schemes. It is concluded that the optimized scheme A needs a smaller land area and has good adaptability; the optimized scheme B needs the smallest land area and has the lowest cost, but has a poor adaptability, and it can only be used in the area without using pantograph disconnector. So the scheme A is recommended.
