Abstract
Power transformers are one of the most important and expensive components of power transmission lines. Reducing costs in the manufacture of power transformers has always been the subject of science. In this study, an ant/firefly hybrid heuristic algorithm has been developed to optimize the materials used in power transformer tanks and therefore to reduce tank costs. Based on this algorithm, an interface program has been created in Visual Studio Program. Using this power transformer tank design computer program, the materials used in the tanks have been optimized. As a result of the optimization, the materials used in the transformer tank, which is designed as a result, are saved between 5% and 15%. By this study, it has become possible to reduce the manufacturing costs of power transformers.
