Yokogawa Electric Corporation has announced the November release of 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 MESA™ energy management and optimisation solution. It runs on a workstation that is connected via 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 energy performance for each individual process unit and piece of equipment. The software additionally 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.
Key features of the software include:
- EP-Analytics’ rigorous calculation engine uses first principle modelling to precisely calculate how much energy is being consumed by turbines, boilers, and other plant systems and equipment. It also calculates the mass balance of the steam and other forms of energy that are supplied to the production processes, and thus can quantify energy losses and other imbalances in the overall system.
- EP-Analytics is designed to support manufacturers’ roll-out of ISO50001. The EP-Analytics software supports ISO50001 methodologies such as the plan-do-check-act (PDCA) cycle as well as activities such as management reviews. The British Standards Institution (BSI) has assessed the EP-Analytics software scope and functionality with regard to the key requirements of the ISO50001:2011E standard. BSI confirms that it is faithfully represented in a Yokogawa report elaborating the functionalities of EP-Analytics that it can be used to reliably visualise data and achieve conformity with ISO50001:2011E.
- As EP-Analytics uses the same energy calculation engine as Visual MESA, which is capable of optimising a plant’s power consumption in real time, while systems and equipment are all operating. This is a task that Visual MESA is designed for, and major energy companies all around the world use it for this purpose. And in the event that a production process needs to be made more energy efficient, Yokogawa also offers a number of advanced process control and operation management solutions.
Kim Hock Teo, Head of the Solutions Service Business Headquarters’ Advanced Solutions Business Division, commented: “Energy regulations are growing ever stricter and this is driving up energy costs. It is clear that our customers are looking for ways to make more effective use of sensors and controllers to improve their energy performance. With its holistic solutions, Yokogawa has much to offer in this respect. I am pleased now that we can add EP-Analytics to our solutions, in partnership with Soteica. Our Advanced Solutions Business Division will continue to deliver the advanced solutions needed to improve energy performance”.
