Open source tool for energy saving and efficient system management

Abstract

In order to improve power quality (PQ) techniques, efforts are made to develop smart sensors that can report near realtime data. Proprietary software and hardware on dedicated computers or servers processes these data and shows relevant information through tables or graphics. In this situation, interoperability, compatibility and scalability are not possible because of the lack of open protocols. This paper presents a new open source solution focused on optimization of power quality and monitoring for low voltage power systems. For that, an open source platform has been developed for computing, storing and managing all of the information generated from smart sensors. We apply the most up-todate algorithms developed for PQ, event detection, and harmonic analysis or power metering. A plugin implementing the S-transform is being developed for the system. To obtain the best input values to this plugin we are developing optimization algorithms to detect the most of well-known disturbances. Our system makes use of cutting-edge web technologies such as HTML5, CSS3 and Javascript to provide user-friendly interaction and powerful capabilities for the analysis, measurement and monitoring of power systems.
