The method focuses on the 的谐波污染问题日趋严重。谐波不仅影响电气设备 minimum of the cost and the optimization of harmonic 的正常工作，还给电网的安全经济运行带来隐 elimination. Some application notices are also given here. A 患[1-2]。目前，消除谐波的方法主要有无源滤波器 high capacity shunt hybrid active power filter designed by this (Passive Power Filter, PPF)、有源滤波器[3] (Active method has been applied in a smelt factory. The detecting result Power Filter, APF) 和混合型滤波器[4-7] (Hybrid shows the filter system meets the requirement of the design and Active Power Filter, HAPF)。PPF 的滤波特性由电网 the harmonic suppression effect is obvious. For China has few experience of HAPF applications till now, the method given 阻抗与滤波支路阻抗的比值决定
