摘要
针对大容量非线性负载谐波补偿问题,采用多台并联有源电力滤波器(APF)并列运行提高系统补偿容量。对多台APF联合运行的协调控制方案进行研究,采用比例和截断的限流方法,保证了每台APF的安全可靠运行。最后提出一种基于级联的分次谐波并列补偿方案,仿真和试验结果表明有优良的谐波补偿效果。
As large-capacity nonlinear load harmonic compensation, this paper present multiple active power filters（APFs） parallel operation to improve the system compensation capacity. For parallel operation coordinated control scheme of multiple APFs ,proportionate current limiting and truncating current limiting ensure the safe and reliable operation of the APFs. Finally, a sub-frequeney harmonics compensation based on cascaded compensation scheme was proposed. The theoretical and simulation results validate the effectivene,,s of the proposed method.
