摘要
为减小谐波对电网的污染和补偿无功功率提高功率因数,针对单相电流,在基于瞬时无功功率理论的基础上,详细研究了对基波有功电流、无功电流和谐波电流的提取方法,并在此基础上提出了一种检测任意高次谐波的方法,该方法控制简单、容易实现。仿真和实验研究都证实了该方法的有效性和可行性。
To reduce the harmonic pollution in the grid and compensate reactive power to improve power factor,considering the single-phase circuit,the method of detecting the fundamental active,reactive current and harmonic current is carefully researched based on the instantaneous reactive power theory.A method of detecting any high frequency harmonics is put forward.Control of this method is simple and easy to realize.Simulations and experimental studies illustrate the effectiveness and feasibility of this method.
