GENERALIZED IDENTIFIER OF THE PRESENCE OF DISTORTIONS IN THE QUALITY OF ELECTRICITY

Abstract

The development of measures to ensure the quality of electric energy is possible only after assessing the actual state of the quality of electric energy in all nodes of the electric network. Therefore, the basis of the system of ensuring the necessary quality of electric energy should be the system of its monitoring.

An approach to the construction of a system for monitoring the quality of electrical energy in real time is presented by developing a generalized identifier for the presence of distortion of the quality of electrical energy, regardless of its type, time of appearance and duration, based on the construction of the spatial-temporal distribution of the information signal and subsequent orthogonal analysis of the frequency-temporal changes of its spectral components. This makes it possible to create a system for monitoring the quality of electric energy in real time, in contrast to existing methods, which use sequential processing of the measurement signal to determine individual indicators of the quality of electric energy, which makes it impossible to conduct it in real time.
