Fundamental Active Current Detection Based on UPF and it's Implementation in DSP

针对有源电力滤波器中广泛采用的基于瞬时无功功率理论的检测技术的局限性,将功率因数的概念引入有源电力滤波器的控制中,提出了基于单位功率因数的基波有功电流检测技术。对该检测方法在DSP数字控制的并联型有源电力滤波器中的实现作了详细的阐述,并给出了部分算法程序,实验结果验证了该检测方法的有效性。

Aimed at the drawback of instantaneous reactive power theory broadly adopted in active power filters, the concept of power factor was introduced into the control system of active power filter. The fundamental active current detection technique based on unity power factor was provided. And its application in shunt active power filter and some arithmetic program were described in detail. Experiments were done on the shunt active power filter based on DSP. And satisfactory result was drawn.
