espanolLa presencia de armonicos de bajo orden en la red electrica causa numerosas perdidas economicas a la industria. Por ello, se estan dedicando muchos esfuerzos en la busqueda de soluciones para reducir su presencia en la red electrica. Una de esas soluciones es el algoritmo que se comenta en esta contribucion. Consiste en la deteccion y posterior compensacion de uno o varios armonicos presente en las corrientes de fase de forma simultanea. Para ello se plantea una etapa de deteccion, donde se extrae la componente del armonico o armonicos a compensar, y otra etapa de compensacion, donde se utiliza un controlador para determinar una componente de referencia a introducir en las referencias de corriente. Este algoritmo ha sido testado experimentalmente y los resultados validan la capacidad del algoritmo para su uso con equipos reales. EnglishThe low-order harmonic presence in the grid is the reason for many economical losses in the industry. Due to this, many efforts has been put in the search for approaches that solve such issue by suppressing them from the grid. This paper deals with one of these approaches. It consists in the detection and the consequent suppression of low-order harmonics by measu ring the grid current. To achieve so, a detection stage, where the considered harmonic to be compensated is extracted, is used along with a compensation stage, where a controller is considered such as to generate a harmonic sequence reference component that will afterwards be added to the final reference currents. This algorithm has been tested experimentally and the good results show its capability to be used for harmonic compensation.
