GENERALIZED IDENTIFIER OF THE PRESENCE OF DISTORTIONS OF QUALITY OF ELECTRICITY

Development of measures to ensure the quality of electricity is possible only after assessing the actual state of electricity quality in all nodes of the electricity network. Therefore, the system of ensuring the required quality of electricity should be based on its monitoring system. An approach to building a real-time electricity quality monitoring system by developing a generalized identifier for the presence of electricity quality distortion regardless of its type is presented, time of occurrence and duration based on the construction of spatio-temporal distribution of the information signal and subsequent orthogonal analysis of frequency-temporal changes of its spectral components. This allows the creation of a system of real-time monitoring of electricity quality in contrast to existing methods, when using which the sequential processing of the measuring signal is carried out to determine certain indicators of the quality of electric energy, which makes it impossible to conduct it in real time.
