Sistema Electrónico Inteligente para el Control de la Interconexión entre Equipamiento de Generación Distribuida y la Red Eléctrica

The changes that are taking place in the electricity sector are causing an evolution of grid towards a more intelligent and efficient model known as Smart Grid. In this context equipment that connect to electric system require an intelligent control of the connection interface. This paper presents the design and development of an intelligent electronic device (IED) with high performance for controlling the electrical interconnection. The device has multifunctional ability to analyze power quality and operate with protections, and its modular architecture allows easy integration in both the development of next generation equipment, as in conventional equipment already installed to adapt to the new context of intelligent management. It has developed a prototype that has been tested with A class tests following the standards IEC 61000-4-30 and IEC 62586-2, and we have performed tests to validate the time response in generating orders and alarm signals for protections. Are shown and discussed some of these experimental results and the experience of integration of this prototype in an experimental smart inverter that is designed to operate in a Smart Grid scenario.
