| Abstract: | IEC-recommended measurement methods of voltage flicker design are too complex and difficult to achieve.On the basis of the IEC flicker measurement principle,discrete algorithm based on fast fourier transform(FFT) can simplify the calculation process of flicker severity.According to the national standards of power quality monitoring equipment general requirements,appropriate parameters were selected to simulate the simplified algorithm.At the same time,in allusion to error analysis of main part of discrete a... |
