摘　　要：柔性直流输电(VSC-HVDC)对孤岛负荷供电将会给交流系统引入谐波,谐波对电网危害很大,因此必须设法将谐波滤除。滤除谐波可采用有源电力滤波器和无源电力滤波器,目前运用较多的是无源电力滤波器。文中分析了柔性直流输电对孤岛负荷供电的谐波构成,运用解析法精确讨论和分析了柔性直流输电对孤岛负荷供电的二阶高通无源电力滤波器参数选取。PSCAD仿真验证了该二阶高通无源电力滤波器参数选取的正确性。The Voltage Source Converter based on High Voltage Direct Current （VSC-HVDC） supplying power to the island load will inject harmonic to AC system, which is very adverse to the power grid. The APF and PPF can be used to filter the harmonic. The PPF is the most common device at present. The consisting of the harmonic from the VSC-HVDC supplying power to the island load was analyzed, and the parameters of the second-order high-pass PPF were discussed by use of the analytical method. The simulation of PSCAD was given finally.
