Pogribnyak N. Methods of quadratic inertial smoothing in calculation of industrial electrical networks loads

The purpose of the thesis is provide of capital investments efficiency and functional reliability of industrial electrical networks with mass electrical equipment by increase of a precision of determination of estimated electrical loads on heat. The researches were carried out by use of methods of probability theory, automatic control theory. The probability distribution law of conductor overheating temperature by random electrical load is determined by the method of statistical simulation. The method of simulation of realisations of random electrical processes with the guaranteed reproduction of the specified law of probability distribution of ordinates and correlation function is offered. The problem of determination of statistical distribution laws of casual processes ordinates on an output of a model consisting of a squarer and an inertial filter section is decided. The engineering methods of determination of estimated electrical loads are vindicated, their efficiency in a comparison with existing is shown. Because of developed methods the project of the instructions on design of electrical loads of the industrial enterprises is offered. Research results can be used in power industry for designing of power supply system of industrial enterprises.
