基于有源电力滤波器的多功能电子负载设计

Design of Multifunctional Electronic Load Based on Active Power Filter

为了解决电能质量治理产品厂内调试和出厂检验的负载问题,提出了一种基于有源电力滤波器(APF)的多功能电子负载。负载由两台APF和一台变压器组成,两台APF采用不同的控制策略,通过监控切换装置的工作模式,能够产生有功、无功、谐波、间谐波及不平衡电流,实现灵活调节和控制。仿真和实验验证了装置的可行性和有效性。

In order to solve the load problem of in-factory commissioning and factory inspection of power quality governance products,a multifunctional electronic load based on active power filter(APF)is proposed.The load consists of two APFs and a transformer.The two APFs adopt different control strategies.Switching the working mode of the device through monitoring,the active power,reactive power,harmonic,interharmonic and unbalanced currents are generated,and the flexible adjustment and control can be achieved.Simulation and experiment verify the feasibility and effectiveness of the device.
