Abstract: 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.
