Description
Summary:•Flicker measurement is mainly divided into two parts: flicker signal detection and flicker calculation.•This paper introduces the common detection methods of flicker signal, such as square detection method, effective value detection method, rectification detection method and synchronous detection method.•The common detection methods are theoretically analyzed, the main advantages and disadvantages are pointed out, and a new fundamental RMS detection method is proposed.•The calculation method of flicker is studied, and the traditional design method of complex filter is improved. The accuracy and rapidity of the algorithm are verified by simulation. This paper mainly introduces the detection method and calculation method of load flicker signal. Firstly, the commonly used detection methods are theoretically analyzed, their advantages and disadvantages are pointed out, and a fundamental effective value detection method is proposed. Then the flicker calculation method is studied. The traditional flicker calculation method is complex and needs the design of some filters. Based on the traditional algorithm, the flicker calculation method is improved, and the accuracy and rapidity of the algorithm are verified by simulation.
