Located in the heart of London, One Crown Place building with its two prismatic shaped towers hosts brand new residences rising 33 storeys into the sky.
Due to our extensive experience in the industry, the main contractor selected Bells solutions to deliver a standby power system to ensure that the building could count on efficient backup power in the event of any power loss.
The system consists of a one FG Wilson generator controlled by a ComAp intelligent controller and an InteliVision IV5 colour screen. The generator controller is connected to an Allen Bradley 1769-L30ER PLC with input and output modules designed to control and monitor LV breakers and tap-offs throughout the building. 

The control and monitoring of the switchboards in the building is achieved via several outstation panels installed in the LV Switchboards and the two risers. Each control panel has a DC UPS with 6 hours autonomy to power the panel if the auxiliary AC supply is lost. 

The solution implemented on this project for the control and monitoring of the risers tap-offs via the network had the advantages of using less material and reducing considerably the installation time. 
In addition to the main PLC, an independent fuel system consisting in a bulk tank panel and a day tank panel is integrated and shares information with the main PLC and other third-party systems.
To monitor and control the PLC system a SCADA system will be supplied through the means of an Inductive Automation software package. 

The SCADA screen will have no moving parts for long term reliability. The Ethernet port will be connected to the PLC network using a copper Ethernet cable via switches. The Allen Bradley SCADA software will be installed on this screen.

From the SCADA screen the operatives will with the necessary security level, monitor and manually operate breakers, view the generator data, carry out tests and acknowledge alarms.
