Savchenko O. Optimization of the modes and perfection of methods of melting of ice-loads in distributive networks 6-10 kV

Оbject - processes of melting of ice sedimentations on the air-tracks of electricity transmission by an alternating current. Аim - increase of efficiency of functioning of rural distributive networks in the conditions of formation of ice sedimentations on the basis of optimization of the modes and improvement of methods of melting of sedimentations on air-tracks 6-10 kV. Methods - simulation techniques, methods of theory of chances and mathematical statistics, methods of theory of fuzzy sets, methods of the mathematical programming, design methods on the basis of indirect analogy. Scientific novelty - the method of choice of specific power of melting of ice sedimentations is first worked out after the mechanical loading on the associate lines 6-10 kV during the melting of sedimentations on them; the method of optimization of the mode of melting of ice sedimentations purchased further development on lines 6-10 kV of rural distributive networks, that differs in the use of multicriterion approach, taking into account of vagueness of data. The method of melting of ice sedimentations is improved on the basis of three-phase artificial short circuit with application of autotransformer of melting of ice sedimentations for the lines 6-10 kV with the wires that have the isolated parts, that differs in the use of noninductive secondary contour. For the lines of 6-10 kV with the wires that have the isolated parts, analytical dependences of basic electric parameters of autotransformer of melting of ice sedimentations are got in the function of specific power of melting of sedimentations, parameters of line and descriptions of the wires. The results of researches can be drawn on by project establishments that engage in development of devices of melting of ice sedimentations on the lines 6-10 kV of distributive electric networks, by enterprises of electric networks wich have the lines 6-10 kV that function in the conditions of intensive action of ice sedimentations.
