The design and construction of a power quality parameters recorder

Abstract

The paper presents the authors’ approach to design and construction of power quality parameters recorder conforming the requirements of IEC 61000-4-30 standard. The recorder was designed and built according to the measurement algorithms developed by the authors. These algorithms meet the requirements of IEC 61000-4- 30, IEC 61000-4-15 and IEC 61000-4-7 standards. Modeling of the applied algorithms and analysis of their sensitivity to variation in some parameters were carried out in a Matlab-Simulink environment. Algorithms for measuring modules were subjected to comprehensive tests verifying their correctness. Also, the tests required by relevant standards or proposed by international organizations, e.g. CIGRE [7], and additional test developed by the authors, were carried out.
