Red de sensores inalámbricos para microrredes eléctricas

Abstract

The development of this project is focused in the design and implementation of a prototype of a network with wireless sensors for an electrical microgrid. This prototype is able to measure characteristic variables of the distribution network establishing communication with a sink node allowing to receive data acquired. For the design of the sensors’ nodes were used LEM® sensors to measure voltage and current. Those sensors work with the standard values of power distribution in Colombia. For the processing of voltage, current, frequency, phase and power factor were implemented in a TMS320F28335 ADSP of Texas Instruments. In order to create the communication link between the sensor node and the sink node were used some Xbee devices of the brand DIGI. In the sink node was used various computer tools as NetBeans and PostgreSQL, for the creation of a software that enable storage and display of data acquired in sensor nodes. Tests were carried out separate of the modules designed and then jointly, to verify the proper operation and compliance with the proposed objectives.
