Yokogawa Releases Energy Performance Analytics Software
Melissa Larson | September 5, 2014
Yokogawa Electric Corp. announces Energy Performance Analytics (EP-Analytics), a software tool that uses energy performance indicators (EnPI) to track how energy is being consumed in a plant, identifies gaps between EnPI targets and actual performance, and helps to identify countermeasures to improve energy performance. The EP-Analytics software is powered by the Visual MESATM energy management and optimization solution.
To improve plant energy performance, it is necessary to first grasp how energy is being used by each process unit. By visualizing and tracking the energy consumption in each unit, inefficiencies can be easily identified and located. The EP-Analytics software runs on a workstation that is connected via an OPC interface to the control system, giving it access to pressure, temperature, flowrate, and other plant data. Based on the Visual MESA simulation engine, the EP-Analytics software uses rigorous first principle models to track energy flows throughout the plant and calculate the energy performance for each individual process unit and piece of equipment. This software also compares actual performance against expected energy performance to pinpoint underperforming units and equipment, and this information can be used by plant personnel to plan specific countermeasures.
