DEVYATKO M. Management of compensatory-symmetrizing devices in the conditions of repeated asymmetry of loadings in supply nets

Subject of inquiry - process of loadings balancing for nods of distributive electrical networks; the work purpose are raise of compensatory-symmetrizing devices use efficiency usein distributive electrical networks by martempering of control systems functioning; methods of researches are based on the theory electrical engineers, on the theory of linear algebra, methods of mathematical modelling and mathematical statistics are used; theoretical results - the method of balancing of voltage which, unlike known, considers agency of repeated asymmetry of loadings and a direct current characteristic of knots of a supply net on accuracy of balancing that provides raise of efficiency of use in supply nets of compensatory-symmetrizing devices for the first time is proved. Management conditions by compensatory-symmetrizing devices of currents and voltage of asymmetrical loadings of users by use of three phase co-ordinates of active components of their conductivity presented simultaneously in system that allows to raise accuracy of balancing at the expense of decrease of a measuring error of magnitudes of return sequence are developed. Has gained the further evolution a principle of balancing of voltage the compensatory-symmetrizing devices affiliated to network junction points placed on small electric remoteness which consists in use caused by asymmetry of a regime of stray load losses of an active-power in a network as an optimisation that increases efficiency of operating solutions and optimises managerial process by compensatory-symmetrizing devices. Practical results - the automatic device for balancing of currents and voltage is created, and also control algorithms are developed by asymmetry of a regime of a supply net. Heading extent - results of work are introduced in the PAT "AK" Vinnytsyaoblenergo" in the form of the device intended for a reactive power compensation and balancing of voltage, in a basis of which work of a control system adaptive regulating of factor of balancing taking into account agency of repeated asymmetry of loadings is necessary. Sphere (area) of use - supply nets of power companies.
