Description: With nearly 1000 beds and 10,000 staff across three sites, Royal Wolverhampton NHS Trust is one of the largest hospitals and providers of acute care in the UK.
From an initial enquiry to advise on replacement of a third-party power factor controller for the critical Heart & Lung Centre, the hospital has now invested in LOVATO Electric Synergy Energy Management for the entirety of the hospital complex.
As LOVATO Electric power factor controllers had already proved reliable in service elsewhere within the hospital, we were contacted to advise on replacement of the existing power factor controller to aLOVATO Electric controller. However, it was clear that for such a critical application the old contactors and capacitors also required renewing. The new system now comprises 12 x DCTL dynamic thyristor modules, controlled by 2 x DCRG8F controllers. The arrangement offers fast and silent operation of the capacitors.
The success of this project has led to the implementation of the LOVATO Electric Synergy Energy Management software platform to manage all energy performance over the entire site.
This will enable them to monitor the main incoming supply quality as well as usage within the different Zones of the hospital across seven substations as well as Main car parks and EV charging points which can then be invoiced to the individual clients.
With multiple combinations of DMG900 and DMG610 meters and to date nearly 200 Synergy licence points. This project has seen successful integration of not only Lovato Electric devices but also many existing third- party devices for gas and water.
In order to integrate these devices a number of different forms of communication were needed. With the DMG 900 in separate locations Ethernet was used on each individual meter to feed back the data on some of the switchboard suites. Elsewhere RS485 and Ethernet combinations were used to make installation easier and also make the project commercially viable as the hospital is a trust and hence financed by the public.
The other challenge faced was incorporating the existing meters via our third party platform and this involved several different manufacturers but owing to the flexibility of the synergy software this was also possible keeping the overall projects costs manageable.
