ОЦЕНОЧНЫЕ МЕТОДЫ ОПРЕДЕЛЕНИЯ ЭКОНОМИЧЕСКОГО ЭКВИВАЛЕНТА РЕАКТИВНОЙ МОЩНОСТИ

Abstract

In the proposed work, the application of the method of relative increments for the analysis and use in practice of the known parameter "economic equivalent of reactive power" is justified; Presented as increment of active power losses in the whole network with increasing reactive power in the network node (i.e., CPU, GPS, DS, etc.). The calculated expressions of the economic equivalent of reactive power using partial derivatives of active and reactive power as well as network voltages are obtained for practical purposes. The analysis of these expressions allows using the estimated values of the parameters proposed in the article and confirming the correctness of this approach, in particular, for estimating the EERP value taking into account the generation of reactive power of an overhead line. The performed analysis of the use of EERP to optimize the composition of equipment of transformer substations, as well as voltage regulation, confirmed the correctness of the corresponding approaches.
