University of Zaragoza energy management system

The University of Zaragoza
History / Objectives
The University of Zaragoza recently implemented an energy management system in its facilities. The objectives were as follows:
- To find out the electric consumption of its buildings and to allocate the corresponding energy costs
- To conduct a comparative study with a view to implementing the good practices being used in buildings where lower consumption is detected.
- To detect deviations in electrical energy consumption caused by potential breakdowns, failures of the air conditioning timing and control systems and misuse of the various installations
General description
Until now, a part of the distribution of low-voltage electrical energy at the University of Zaragoza has been carried out from 4 transformers, but it has not been possible to break down the energy billing data. By installing 9 CIRCUTOR CVMK2-ITF-405 power analyzers with K2-EXP-SD-MODBUS/TCP cards, the University has beenable to solve this problem, as they can now monitor consumption through the PowerStudio Scada program
Remarkable aspects / Results
- Them not only visualise data on instantaneous consumption but also save logs of supply voltages, power consumption, harmonic content, wave quality and power factor
- With this software they can get alarm signals when deviations in the nominal voltage values, disconnections of the main switch or excess consumption of reactive energy are detected
- The software configuration displays the supply tension, phase current and power consumed by the 9 power analyzers on a single screen, or, with a simple click on the map of the campus served by the analyzer in question, provides more detailed information
