Operación eficiente de los bloques generador-transformadores en las unidades de generación distribuida

in this paper was determined the most efficient operation of generator-transformers blocks of distributed generation unites that are operating to serve the electric power to a higher voltage grid. for this purpose, a tridimensional model of efficiency with better results is proposed taking into account the combined losses of the generator and transformer, the load level and the power factor of the system. in the optimization process a particle swarm algorithm was employed. the developed method can be used to select the transformer and to obtain the most efficient operation of these power plants as it is possible in field conditions. as an example its application to a 1150 kva generation unite of cienfuegos′s province is shown.
