The development of flickermeter according to standard IEC61000-4-15 and modeling consumers which produce flickers in the power network

In this paper are defined procedures for a flicker measurement according to standard IEC 61000-4-15 and the definition of a flicker is given. The software for measuring a flicker severity was developed and this software was implemented on concrete example. The developed software is based on digital signal processing. Input data is a certain file or data from the computer's RAM memory and the result is a value of the flicker severity. This concept allows that the developed software can be used both for the flicker measurements and for a simulation of flickers in the power network. A hardware support for the software can be any acquisition card which satisfies minimum conditions concerning the flicker measurement and a range of input signal. The aim of this work was to develop a universal application that can be used for the flicker measurement and also for the flicker analysis which can be made after simulations in the power network. In this paper is made a model of characteristic consumer which produces flickers in the power network. The conclusions in this paper relate to the procedures of development of a flickermeter and to the example that is analyzed in this work.
