FG Wilson Engineering Ltd…Designed to Deliver More
FG Wilson Engineering Ltd is a truly global company with over 3,000 employees and 40 years of experience in the supply of diesel and gas generator sets. The FG Wilson product range from 5.5 - 2,500 kVA, includes open and enclosed generator sets providing prime and standby power - from standby domestic use, right up to power modules with the ability to operate as complete power stations supplying electricity to national grids.
FG Wilson serve and support customers all over the world through its Global Dealer Network. The UK has been a particularly strong market for them for many years. With the back-up of FG Wilson's power solutions team, Dealers can meet any power requirement, no matter how complex. One example of a project for which FG Wilson are providing power is the Royal London Hospital.
The Royal London Hospital has been one of London's landmark buildings since it's construction in Whitechapel in the East End of London since 1757. It has now been improved with a re-design by HOK, one of the world's most acclaimed architectural design firms. The new hospital features a cluster of inter-connected contemporary glass buildings, including two 18-storey towers and one ten-storey tower.
Redevelopment of the hospital got underway in May 2006, with completion of phase I scheduled for 2012, and phase II due to complete in 2014/2015. FG Wilson was appointed by contractor, Skanska as a design phase partner. Following this design phase, FG Wilson was appointed to supply and install high voltage generator sets.
FG Wilson's role in the project entailed the design, supply and integration of 11MVA of standby diesel generation to be incorporated into the 11kV network within a purpose built plantroom on the 18th floor of the tower.
To meet the stringent acoustical requirements, the design encompassed individual acoustic enclosures arranged within the plant room. This space included switchgear room, control suite, daily fuel service room, exhaust gas treatment and leak detection.
Due to the critical power demands of the hospital, there was a high level of resilience required in the design of all aspects of the scheme. This involved an N+1 arrangement of 5 number FG Wilson P2000 Generator sets. These generators comprise of the Perkins 4016 TAG2A Prime Mover coupled to a Leroy Somer LSA54 11kV Alternator.
To manage the complex nature of the control and distribution of the electrical power a Duty / Standby PLC (Programmable Logic Controller) and a network of remote input & output PLC outstations were implemented throughout the hospital buildings, interfacing through multiple HMI (Human Machine Interface) & SCADA (Supervisory Control And Data Acquisition) touch screen workstations. This high-level control system included generator control, neutral earthing resister control, HV synchronizing, fuel system monitoring and power management of the high and low voltage distribution system throughout the site.
One of the key elements of this project was the delivery of 2.1 MWe of critical power within 15 seconds of mains failure, whilst meeting the G3 performance class of ISO8528-Part 5.
To achieve this challenge, we incorporated the philosophy of 'Dead Bus Synchronisation'. This involves the start-up of the 5 generators together, and while running up between 1200-1500 RPM the excitation is switched on, allowing the gensets to synchronise together onto the bus bar, ready to accept load on voltage stabilisation.
Another complex aspect of the project was the detailed factory validation of the system prior to dispatch from the FG Wilson's manufacturing facility at Larne, Northern Ireland. This type of rigorous FAT (Factory Acceptance Test) allowed FG Wilson to flex the muscles of its Power Solutions team and their in-house resources.
As the project nears the successful completion of phase I, Ian Neville, Skanska's Operations Manager commented, "We are very pleased with the professional and high quality service that we have received from FG Wilson on this project."
Continuously innovating, FG Wilson has invested millions of pounds in recent years in their manufacturing facility in Larne, Northern Ireland. State of the art technology has been incorporated into new production lines and test facilities. The Larne site also encompasses Europe's largest hemi-anechoic chamber - providing advanced acoustic research and testing capability. The company also has manufacturing plants in Brazil, China, India and the United States.
FG Wilson's strength is in their Dealer network and in-house team of highly qualified electrical and mechanical engineers, whose power expertise includes:
- Advanced control and synchronisation systems
- Remote cooling
- Exhaust silencer systems
- Room acoustic treatment
- Weatherproof and acoustic enclosures
- Specialist environmental protection
