To the problem the optimization of asymmetric regime work of distributive networks
T.T. OMOROV, B.K. TAKYRBASHEV

It is considered the three-phase distributive electrical networks (DEN) as an object of control at their asymmetric regimes. Such regime work of DEN are not optimal, in particular, they lead to considerable losses of active power in the network and supplying transformer substations, that requires a search for effective ways to solve this problem. It is offered a new approach to the optimization of asymmetric regime work of DEN on the basis of adaptation of consumer loads through their switching from one phase to another. The process of switching control is carried out by automatic control system, consisting of a digital regulator and an object, including the group of electricity meters with the switching elements. In the purpose of evaluation of quality and efficiency of the DEN functioning is entered criteria function, characterizing the losses of active power in the network. It is synthesized the regulator, providing the formation of control actions on the object based on the optimization of the considered criterion.
Keywords: three-phase network, asymmetric regime, losses of power, optimization of regime, digital regulator, switching element.
