SOFTWARE AND ALGORITHMIC SUPPORT OF HARDWARE SYSTEMS REDUCING THE IMPACT OF PULSE DISTORTION IN POWER NETWORKS
The article presents development of algorithms and software and hardware systems improve the quality of supply of electricity in distribution networks through an active digital filter. The algorithm of identification of the network signals components using an orthogonal wavelet basis is developed. It is experimentally proved that the most dangerous are broadband impulse noise with aperiodic component. When comparing the active filtration algorithms, it is established that the application of Fourier basis requires a high filter order, which leads to a significant phase delay and error. The choice of wavelet bases for more efficient identification of the structural components of the supply voltage signals is made. The article presents the solution of a set of tasks aimed at improving the quality of electricity in electric power systems. As a result of the carried out researches the mathematical and software of the active compensator of conductive hindrances in electric power systems is developed. The developed algorithms and methodology for identification of structural components of non-sinusoidal signals of the network (voltage and current) in the electric power system with the application of orthogonal wavelet bases. Application of the developed complex of programs of detection of violations of indicators of quality of electric energy during monitoring allows to control quality of electric energy in real time. There is no need to collect statistical data, the developed methods allow timely application of the algorithm to improve the quality of electrical energy.
