Powersystmes energise Leeds GSC first phase

May 15, 2018

Powersystems update on the Leeds General Infirmary Generating Station Complex (GSC) HV Switchgear replacement project –  the first phase has now been energised.

To meet the increasing electrical load requirements of Leeds Royal Infirmary Powersystems successfully secured a £1.2m contract with ENGIE to replace the HV switchgear against strong local competition.

The added complexity of replacing the existing HV switchboard and NER in 4 phases within the existing HV Switchroom, showcases Powersystems technical ability.   Our reputation for exceeding expectations on technical know-how, quality and safety being the major contributor to our success.

Whilst ENGIE Services Ltd responsible for the wider contract to replace and upgrade the generation and HV/LV infrastructure feeding Leeds General Infirmary buildings, Powersystems scope was to deliver the following:

  • Design, supply, install and commission a new 17 Panel 11 kV Switchboard, including all protection relays and system interfacing
  • Remove an existing 18 panel 11kV, double busbar switchboard
  • Carry out temporary diversions and connections on new and existing HV cabling to ensure the continued operation of the generating station complex
  • Carry out scheduled cable changeovers from existing to new HV equipment
  • Supply and install a new Neutral Earthing Resistor Panel (NER) within the HV Switchroom, including all HV, earthing and control cabling
  • Supply and install all control cabling between the new HV switchboard and local HMI/DCS panels
  • Configure and commission relays for all Incomers, generator feeders and transformer feeders
  • Use in house expertise to configure and commission relays to use the new communications protocol IEC 61850 allowing for remote circuit breaker operation and relay monitoring through HMI and DCS.
  • Supply and install 2 new 1500 kVA, 11,000/415 V KNAN transformers as well as associated LV AWA single core cabling to the main LV panels.
  • Design, supply, install and commission a new 110V DC battery charger supplying the HV switchboard, NER Panel, NER control panel and LV panels within the GSC
  • Install cable containment throughout the GSC for new and existing HV/LV cable
  • Provide all operation and maintenance manuals as well as onsite training for the operations staff

Powersystems have  successfully worked throughout the delivery phases with our client and their sub-contractors, reinforcing our reputation for technical competency, flexibility and commercial integrity.

This has subsequently led to our client inviting us to tender a number of further complex HV equipment replacement projects across the UK.
