The reconfigurable building

End User: Major International Financial Institution

Location: City of London

Building on an innovative design from the client's consultants, new LV Distribution and UPS's were installed in this large London site with minimal downtime. Several parts of the remaining infrastructure posed unusual challenges in controlling the LV power. A Triple redundant PLC control system (sometimes referred to as Triplex) was installed as part of the project. This control system routed the power around pinch points in the building allowing the supply to be maintained whatever the failure scenario.

The control system is installed on multiple floors and configured in such a way as to provide no single points of failure. The generators, LV distribution and load shedding are all controlled from the new system. Operator control touch screens are provided at multiple locations in the building to allow the FM team total visibility of the critical power distribution in the building.

Critical power with the Penguins

End User: Ministry of Defence

Location: South Atlantic

 

As the infrastructure in these three critical remote sites had reached the end of its life, a project was undertaken to provide new power supplies. The power was provided by 4 LV generators which operated in a 2N configuration. A Triple Channel PLC control system (sometimes referred to as Triplex) was supplied to control the generators and LV load shedding automatically. This control system was designed to have "No Single Points of failure"

When the power demand was low the system automatically sheds a generator in order reduce site fuel consumption. In times of heavy demand (or conflict) two generators are run to provide the necessary security of power for these crucial sites. Duty rotation of the generators is also taken care of by the control system.

Full diagnostics and control of the system is achieved from HMI's located in the LV switch room and the living accommodation - a vital feature when the winter weather features high winds and deep snow.

And the penguins? Once the system was operational with a resilient multi-channel design keeping the lights on, there was time for a little site seeing.
