Algoritmos e Modelos do LDC e do OLTC: Uma Análise Comparativa para Estudos de Fluxo de Carga

Abstract

The purpose of this work is to verify the simulation equivalence of both regulators by means of simulations with OLTC (on-load tap changer) and LDC (load tap changer) controllers. The simulation was based, through the mathematical modeling of both methods, to create scripts and simulate them using a generic problem of load flow as a test system, comparing the values of the tap's obtained by means of each method, such equivalence. The simulation of the test system was performed in Matlab® software. After the simulations, it was possible to infer the equivalence in terms of simulation of the algorithms of both regulators for the test system used, since in all the simulations performed, the OLTC method tapes presented values identical to those simulated using the LDC method. Simulations as such demonstrate the feasibility of in-depth studies on load flow algorithms. However, it is necessary to improve simulations in larger test systems in order to verify the equivalence in question, as well as the implication of the same in said systems.
