Development of the Method of Determining the Power and Electricity Losses in Distribution Network of Shop Electrical Supply
Abstract
For development of a formalized method of determining the power loss in a shop network was used such research method like simulation of a shop network performance for determining the coefficient of increase of the power loss in regard to the minimum section. The results was achieved—the method of calculating the power losses taking into account network design features has been developed. One of the most labour-intensive stages of determining the total cost of the construction of a shop electrical supply network is determining the power losses in conductors of the distribution and supply network, due to the branching out of a network and various modes of electricity consumers. Therefore, the formalization of the process of determining power losses is a topical task. Practical significance of the research is that developed calculation algorithm allows to formalize the definition of power losses both for radial and for trunk supply circuits, the calculation accuracy is 4-7%. The calculation results allow to make electric balance in shop networks and assess their technical and economic parameters. Unlike the existing methods for calculating consolidated costs, this method takes into account the correspondence between cost of active electricity and the capital costs. Consider the variability of this ratio is an important part for choosing a reliable power supply network option.
