Business Headquarter Site – Complex Electrical Network Control System

plc

 

This project involved the phased replacement of a triple redundant PLC voting control system which had expired and become obsolete with no maintenance support available for the system and a large number of faults present on the network which was responsible for controlling all utility supplies, on-site generation and UPS systems as well as large number of static and automatic transfer switches split across 10 main electrical control panels through the site and 16No. 11/0.4kV transformers.

 

The works were implemented across a number of weekend shutdowns of the critical panels requiring temporary supplies to be put in place and each section tested at the end of each weekend to ensure business as usual status could be achieved by Sunday night for return to work on Monday morning.

At the completion of the individual works a full site test followed by a site acceptance test for the FM engineering services provider’s acceptance was completed and successfully handed over.

The system retained its resilient triple voting PLC system and a high specification HMI was put in place providing high quality and easily interpretable statuses of the building to be understood at a glance. This project was based on repeat business from a similar project delivered to the same client two years previously, with this project being as successful, if not more than the original.

We work closely with a market leading automation and controls specialist contractor and undertake a number of these high precision critical system projects every year. Please contact us now to discuss your needs for such a system of triple voting, hot standby or other automated controls for your electrical network. We also undertake high quality bespoke and supportable electrical network management systems.
