　　并联有源电力滤波器的工作原理是主电路向电网注入大小相等、方向相反的电流量来达到谐波抑制，其性能主要包括动态响应速度和稳态补偿精度。PI控制应用于谐波抑制具有动态响应快、稳态精度低的特点，重复控制具有稳态精度高、动态响应慢的特点，为综合两者的优点，提出将重复控制与PI控制进行串并联的复合控制策略：先将一重复控制与PI控制构成串联复合，再将串联复合与另一重复控制并联构成串并联复合。并将其与PI控制、串联复合控制和并联复合控制的谐波补偿性能分别进行了仿真对比研究与实验验证。仿真结果表明串并联复合控制具有更好的谐波补偿稳态结果和动态响应性能，实验结果证明了该方法的可行性与正确性。

Outputting compensated current by main circuit which is equal to harmonic current with reverse direction is the basic principle of shunt active power (SAPF). The performances of SAPF contain dynamic response and static precision. Single PI control applying to SAPF has the characteristics of a low static precision and fast dynamic response, and the repetitive control has the characteristics of a high static precision and slow dynamic response. To colligate the two controllers’ advantages, series-shunt compound control method which makes repetitive control and PI control in series and in shunt is put forward. The performances of harmonic compensation with PI control, series compound control and shunt compound control are all emulated and validated. Emulated results indicate that the series-shunt compound control has better performances in static precision and dynamic response, and experimental results verify the viability and effectiveness of the proposed control method.
