Chernikova L. Methods of calculation of random process characteristic in linear filter of electromagnetic compatibility estimation models in public electrical systems

The subject of inquiry are the reactions of dynamic systems' filters on random conductive electromagnetic interferences in public electrical systems. The purpose of the thesis is guarantee of estimate reliability of electromagnatic campability in projectible and acting power-supply systems. The researches were carried out by use of methods of random processes theory, automatic control theory. The new methods of calculation of nonstationary random reaction charactaristics in linear filters of dynamic models for electromagnatic campability estimation are developed. This methods allow to decrease electromagnatic campability providing costs and waste from poor electric energy. Analitical expressions for determination of correlative functions and dispersions of filters reactions on nonstationary interferences in power electric systems are received. Those allow to avoid computational solutions. The new analitacal method of voltage oscillation dose is developed, which differences by account of probabilistic distribution of process after quadratic inertial smoothing. The necessary prerequisites for development of flicker dose calculation methods are created. The proposed methods have been included in "Propositions about perfection GOST13109-97 in part of voltage oscillations". Research results can be used in power industry for designing of power supply system of public electrical systems.
