Equivalent Model of Electric Power System of the Kyrgyz Republic and Analysis of Modes in Case of High Perturbations

Abstract

Modern electric power systems are characterized by a very complex structure of electrical connection circuits and a huge number of elements (stations, loads, synchronous compensators, etc.). Difficulties of calculations at the occurrence of large disturbances and analysis of the obtained results quickly increase with the increase of the number of elements of power systems, which cause in steady and transient modes various phenomena and accompanying processes, which cannot be analyzed without taking various kinds of equivalence. Therefore, it is generally advantageous to simplify power grid schemes in a stability analysis. In action, it is sought to obtain a scheme that reduces the number of elements involved, but at the same time allows for sufficiently reliable and practically foreseeable results. Because the problem of building models that best reflect actual processes is always relevant. This article deals with the proposal for system equivalence in relation to the Electrical power system (EPS) of the Kyrgyz Republic (KR).
