| Abstract: | Voltage fluctuation and flicker are two important indices for power quality assessment. Through the detailed analysis on the flicker testing system given by the design specifications of IEC, a compensating-iterating algorithm which can accurately calculate the instantaneous perceptibility is put forward and then the short term severity and the long term severity are obtained. A flicker testing system based on the Labview platform is designed, the practical measuring results show that this system can be used to measure the voltage flicker with a higher accuracy. |
