UK cogeneration specialist ENER-G has launched a two-in-one combined heat and power (CHP) remote monitoring and control system andà‚ energy management system (EMS).
The new technology, called E-Power, willà‚ optimise performance of both the CHP system and wider energy plant within a building – providing cost and carbon savings for customers.
“There are too many poor examples of CHP being installed as a ‘fit and forget’ technology,à‚ without proper integration with the master building energy management system”, said Chris Marsland, ENER-Gà‚ Technical Director, who led the in house R&D team. “E-Power doesn’t just provide an isolated view of CHP performance, it facilitates precise control and measurement of energy production and use across the entire site. This will lead to better visibility of energy use, maintenance requirements and performance targeting.”à‚
In 1984 ENER-G collaborated with the University of Manchester to pioneer the first modern CHP remote monitoring and control system. This made low carbon CHP technology viable on a global industrial scale. The R&D team was able to build on this experience andà‚ knowledge to develop the new E-Power system, investing à‚£1 million in the project.
Traditionally CHP systems operate independently of aà‚ building’s energy centre controls or metering. This often means that the boiler or system plant controllers are not optimised to extract the maximum value from the CHP unit.à‚ E-Power is designed toà‚ enhance the value of the CHP system through closer integration with the wider building, including:
à‚·à‚ à‚ à‚ à‚ à‚ à‚ à‚ à‚ Dedicated boiler optimisation algorithm, ensuring best balance between CHP and boiler operation.
à‚·à‚ à‚ à‚ à‚ à‚ à‚ à‚ à‚ Dedicated CHP thermal store control ability.
à‚·à‚ à‚ à‚ à‚ à‚ à‚ à‚ à‚ Ability to interface CHP with existing and future plant.
à‚·à‚ à‚ à‚ à‚ à‚ à‚ à‚ à‚ Data collection from an extensive set of energy meters including direct MBus connection and BACNetà‚ to capture energyà‚ information on the full building, not just the CHP meters.
à‚·à‚ à‚ à‚ à‚ à‚ à‚ à‚ à‚ Always-on connection and visibility of whole site energy performanceà‚ – through the E-Vision cloud-based web portal.
E-Power is built into ENER-G’s CHP unitsà‚ and monitors and controls more than 200 parameters on each CHP unit.à‚ This improves engine control by monitoring ignition energy levels, knock levelsà‚ and spark advance. It also enhances synchronising routines and power control.
The system alerts ENER-G’s national service centre to any anomalies or operational issues, enabling them to run diagnostics, rectify problems remotely, or schedule an engineer visit, if necessary.
