Control Room Design and Build Project

Control Rooms are where people and technology meet.
A new Energy Control Centre for Manx Electricity

With a view to the future, the Electricity Authority wanted to expand and diversify the power supply in the Isle of Man. This expansion required the creation of a dedicated combined control centre for the Island.

Electricity Control Room

During normal operation one man should be able to control 4 plants and monitor up to 15 separate display screens whilst at times of high activity allowing a team of 7 or 8 engineers to work effectively together in the same control room. This was achieved using the combination of a central video wall and careful layout of desks and screens.

The Hexatec teamwere invited to propose an integrated solution.

The Space

The construction of new offices and workshop facilities alongside the new CCGT plant provided the perfect space for the new Control Centre.

The Design

Working with MEA staff and the architects (www.savagechadwick.com) a design was agreed.

A central control position, and a video wall capable of displaying any combination of control screens, allow one man operation. Additional workstations allow several engineers to work together, with shared information, on the video wall. An adjacent meeting room is used for operational planning and as a visitor centre.

The Technology
As an almost totally computerised control facility, it was necessary to future-proof the design so the room was flood- wired with CAT5e cable to provide Ethernet networks for control and information systems. To reduce noise and heat load the majority of computers were located outside of the control room with the control screens and keyboards driven by KVM extenders over Cat5.

As the video wall was fundamental to the operation, great care was taken to select technologies that could be viewed in natural daylight and could display any combination of control screens over Ethernet.

By bringing together many different systems into the same control facility, it was essential that colours and symbols on each system had the same meaning. A control screen standard was devised and applied to all control system displays. (See Operator Screen (HMI) Design Guidelines.)

Despite the technology, it is impossible for one operator to continuously monitor so many separate systems, so a centralised system was developed using networked OPC technology to provide an overview display of all operations (see Centralised Operational Control in our Scada sub-site). OPC was also used to integrate information for trading and management purposes.

Comfort and ease of access to screens, keyboards and control information is essential to any control room design, so great effort was taken to select the correct control room furniture. The control desks and seating were provided by specialist supplier, whilst other fixtures were sourced locally.

The completed control centre was opened by the Duke of Edinburgh.
