Reliability of Electrical System Upgrade: Principality Stadium
Background
Principality Stadium:
De-Ugonec Services were tasked with upgrading the electrical supply at the Principality stadium in readiness for the West Vs Australia rugby match to ensure greater reliability. The project involved establishing a substation to allow 3 off 1.25MVA generators to supply the 11kV ring.
Technical Requirement
- Design & construct a concrete base suitable for the 11kV swtichgear and grp enclosure
- Design, supply and install a ring main unit with VIP relay and self powered protection scheme
- Install 150m of high voltage cable at high level on ladder rack
- Install cable terminations and cable joints
- Provide SAP to isolate cable section to allow connection
- Issue permit to work
- Sanction for test on behalf of the Principality Stadium on their 11kV network
- Test & Commission switch gear and cable circuits by use of a very low frequency VLF pressure test
- Carry out a grading study to match up the protection scheme
Outcome
A new generator sub station was established in a suitable location, allowing generators to connect up to the 11kV network which now provides security of supply during matches and events at the stadium.
