ENER-G puts an Energy Management System into its CHP
Manchester, UK (PRWEB UK) 30 April 2014 -- UK cogeneration specialist ENER-G has launched a two-in-one combined heat and power (CHP) remote monitoring and control system and energy management system.
The new technology, called E-Power, will 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, without proper integration with the master building energy management system", said Chris Marsland, ENER-G 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."
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 cogeneration technology viable on a global industrial scale. The R&D team was able to build on this experience and knowledge to develop the new E-Power system, investing £1 million in the project.
Traditionally CHP systems operate independently of a 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. E-Power is designed to enhance the value of the CHP system through closer integration with the wider building, including:
- Dedicated boiler optimisation algorithm, ensuring best balance between CHP and boiler operation.
- Dedicated CHP thermal store control ability.
- Ability to interface CHP with existing and future plant.
- Data collection from an extensive set of energy meters including direct MBus connection and BACNet to capture energy information on the full building, not just the CHP meters.
- Always-on connection and visibility of whole site energy performance - through the E-Vision cloud-based web portal.
E-Power is built into ENER-G's CHP units and monitors and controls more than 200 parameters on each CHP unit. This improves engine control by monitoring ignition energy levels, knock levels 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.
Customers can gain instant insights into their CHP performance via a touch screen mounted onto the unit. This supplies data that can be accessed in graphical form and at various levels of detail.
The E-Vision web portal provides total visibility of the entire energy plant, including the cogeneration system. It supplies live operational, monitoring and control data, as well as historical information via a cloud-based system. As such, data is accessible 24/7 via smartphones, tablets or PCs.
By presenting this data graphically and at various levels of detail, E-Vision provides a powerful operational improvement, compliance and reporting tool. It automatically generates email reports and alerts, which can be customised to a client's requirements to keep them appraised of all aspects of energy performance and assist with management reporting.
Standard reporting covers CHP performance and availability for contractual monitoring, CHP daily and half hour data reporting to help optimise CHP operation, together with CHPQA reporting to meet statutory requirements.
E-Vision helps improve proactive maintenance since trend analysis software highlights minor defects and issues before they escalate. ENER-G is able to monitor the wider building energy infrastructure to optimise operation of the CHP system, boiler plant, absorption chiller, thermal stores, etc. By taking a holistic approach, a site-wide energy reduction plan can be implemented to maximise cost and carbon savings.
ENER-G, based in Salford, Greater Manchester, is Europe’s leading provider of small scale CHP systems (from 4kWe to over 10MWe in size). The company designs, builds, operates and maintains CHP units, with approximately half of the installed assets financed by ENER-G under its Discount Energy Purchase scheme on a pay-as-you-save basis.
