Bandura I. Models and methods of tensions symmetrization and reactive power compensation in distributing networks of energy supplying companies.

Object of research - modes of nutritious electric systems 10 kV the power supplying companies, and also distributive networks 0,4 kV electric power consumers; the work purpose is additional decrease in losses of active capacity in electric networks and improvements of quality of the electric power at the expense of introduction of models and methods of complex use of condenser installations for balancing of pressure and indemnification of jet loadings; the method of symmetric components, methods of matrix algebra, methods of linear and dynamic programming and not scalar optimization are used; theoretical results - the method of balancing of pressure which, unlike known, is based on change of additional losses of active capacity in networks of a food and electric power distribution that allows to use condenser installations in interests of the power supplying company or the electric power consumer for the first time is offered. Had the further development methods of complex use of condenser installations by decomposition of a problem of management by an electric mode with the subsequent unbinding of separate subtasks in the optimum sequence providing necessary level of indemnification of jet loadings at minimum asymmetry of the pressure. The method of calculation of optimum levels of indemnification of jet capacity in distributive networks of the power supplying companies which, unlike existing, considers necessity of indemnification of constant losses of jet capacity for transformers 10/0, 4 kV, decrease in losses of active capacity in feeding electric systems, and also dissimilarity of expenses an establishment of condenser installations is improved. It allows to prove optimum sequence of installation of condenser installations in knots of a distributive network. Practical results - consist in working out on the basis of the received theoretical results of algorithms of management of asymmetry of pressure (currents) in networks of the power supplying companies by means of condenser installations of asymmetrical execution which can be realized in microprocessor control systems. Their introduction will promote decrease in losses of capacity and level of asymmetry of pressure in distributive networks of the power supplying companies. The technique of a stage-by-stage establishment of condenser installations 0,4 kV and 10 kV which provides decrease in losses of capacity at the minimum recoupment of capital investments is developed. Introduction degree - results of work are introduced in Public Open Society "Volinoblenergo". And on chair of an electrical supply of Lutsk national technical university for preparation of specialists in a direction of preparation 6.050701 - the electrical engineer and electrotechnology. Sphere (area) use - power energy.
