BG Energy completes West Burton CCGT commissioning

Commissioning of the ventilation, extraction and air handling equipment at EDF Energy's new 1,320MW CCGT (combined cycle gas turbine) power station at West Burton, Nottinghamshire, is now complete.
The turbine halls house 36 extractor fans, 26 temperature sensors and 10 heater units (140A), all controlled by Trend BMS (building management system) technology installed and commissioned by BG Energy. "Everything is controlled by Trend technology, including all the air handling units and the fan coils," confirms Wayne Hudson, C&I technician at EDF Energy. "This doesn't just apply to the turbine halls themselves, but also to the electrical substation, control room and water treatment plant areas. We now have a range of diagnostics available to us." Each turbine hall houses a 290MW gas turbine, with an HRSG (heat recovery steam generator) that, in turn, powers a 150MW steam turbine – together achieving thermal efficiency of around 60%. Procured and managed by EDF-CIT, the in-house delivery vehicle for this type of scheme, West Burton B is a three-turbine hall facility running on natural gas. Sited next to the original coal-fired power station, construction started in 2008 with the intention of supplying electricity to 1.5 million homes. The main electrical contractor, SPIE Matthew Hall, appointed BG Energy Solutions to install and commission the control systems. BG Energy was also tasked with manufacturing various control panels. "While the Trend control technology is doing a great job locally, in the future we may want to consider an Ethernet-based system with a SCADA head-end unit," states Hudson. "This will permit a holistic view of the whole system from a single location. Any alarms or failures in run-time will be flagged up instantly, thus providing a more integrated site."
