摘要
本文提出了均值滤波器对Fryze时域功率定义下的有功电流实时检测方法,该滤波器为一具有线性相位的有限冲激响应(FIR)数字滤波器,可以使得应用于三相电路的控制系统在三分之一个周期处就跟随电网的变化,单相电路的控制系统在一个周期处就跟随电网的变化,在理论分析的基础上,本文对该方法进行了仿真。
The paper puts forward an active current detection of the Fryze definition based on the mean filter. The filter is a finite impulse response (FIR) digital filter. It makes that the control system can follow the power system after three-one period in three-phase system. The result makes it come true.
