CHOICE OF PARAMETERS OPTIMIZATION OF DISTRIBUTIVE ELECTRICAL NETWORKS WITHIN TOWN DISTRICTS WITH FEW-STOREYED BUILDINGS
Abstract
In this paper the brought results over of researches of parameters and modes of electric networks by tension 6 (10) and 0,38 кВ in relation to reliability and capital investments. analysis has been made concerning existing methods of pre-design parameters estimation for the electric power supply networks within a settlement town with few-storeyed buildings.Their deficiency was accentuated. A methodology is offered herein for an optimum power determination of transformer substations, and optimum sections of 0.38 kV power transmission lines taking into account a probability character of the load applied. When compiling the electric power supply circuit for optimum shape, parameters, voltage, voltage adjustment principles and reactive power compensation. Solutions of such a kind are substantiated by feasibility comparisons of a series of technically acceptable variants of electric power supply networks. An important measure that facilitates a choice of the most economical variant is the predesign estimation dealing with a matter of choosing the optimum power of network trans-former substations (TS) by means of calculation formulae. Perfection of existent methods became the aim of researches on the basis of separate account of factor of reliability of network 0,38 кВ and 6-10 кВ A methodology is offered herein for an optimum power determination of transformer substations, and optimum sections of 0.38 kV power transmission lines taking into account a probability character of the load applied.Keywords: distributive electric networks, the brought charges over, number of consumers, choice of section.
