单相并联型APF实验平台的设计

Design on Experimental Platform for Single-phase Shunt APF

为提高有源电力滤波器(APF)研究开发的效率,设计了一种多功能、开放性、全数字化的单相并联型APF通用实验平台,对实验平台的功能需求、工作原理、软硬件设计等问题进行了研究,最后搭建实际的实验平台以验证所设计实验平台的软硬件系统。实验中谐波电流采用单相电路无锁相环同步检测法,电流控制方法采用单极性滞环控制法,直流侧电容电压控制方法采用基于有功功率平衡的控制方式。实验结果表明,所设计的单相并联型APF实验平台方案和软硬件系统正确有效。

In order to advance the efficiency of active power filter （APF） research and development, a multi-function- al, open and all-digital parallel APF common experimental platform are designed, the functional requirements of the experimental platform, working principle ,the design of general hardware and software issues are further analyzed.Final- ly, a practical experimental platform is built to verify the hardware and software system of the designed experimental platform.The experiment of harmonic current in single-phase circuit without phase-locked loop synchronous detection method ,current control method using unipolar hysteresis control method of direct current capacitor voltage control method using the control method based on acitve power balance.The experimental results show that the scheme and hardware and software system of the single-phase parallel APF experimental platform are correct and effective.
