Representação simplificada de um alimentador de média tensão da região metropolitana de Goiânia

Abstract

Studies on electric power systems, given its physical dimensions and power ratings, as well as its economic and social relevance, are typically conducted through computational simulations based on mathematical models of electrical grids, generators, loads, substations, and other components. The limitations regarding “bench testing” and even field testing create a demand for test systems that represent real networks for computational simulations, which can support various types of analysis. In this regard, benchmark test systems have historically been used as reference models. Depending on the objective or phenomenon to be analyzed, there are specific reduced test systems whose mathematical models are more appropriate for focusing on studies related to operational planning, system stability, and network protection security, among other possibilities. This paper develops a reduced equivalent of an electrical grid that serves the metropolitan area of Goiânia, based on data available in the literature as well as data requested from the local utility company, and it is representative of the dynamic behavior of this small portion of the National Interconnected System (SIN).
