2005-10-28 - · Upgrade of the 400/132kV substation includes a new supergrid transformer and second 132kV bus coupler
· First project to adopt the standardised NICAP approach to substation control and protection systems
ABB has been awarded a turn-key contract by National Grid to upgrade a 400/132kV substation near Stoke-on-Trent. The project will provide additional transformer capacity to enable Central Networks, the local DNO (Distribution Network Operator), to cater for load demand growth in the north of Stoke and surrounding areas, and to ensure continued compliance with security standards. The increased capacity, together with the installation of the second 132kV bus coupler, will also permanently relieve some of the demand on Rugeley Substation.
The main elements of the project will be the installation of a fifth 400/132kV 240MVA SGT transformer and a second 132kV bus coupler, and it will also be the first project to feature ABB’s new type PMC dead tank circuit breaker, rated for 123-170kV and 40kA, that has recently been type registered for use on UK power networks.
NICAP
This will be ABB’s first implementation of bay solutions for the substation protection and automation systems based on National Grid's standardised NICAP (National scheme for Integrated Control and Protection) philosophy. By using pre-engineered, pre-tested and pre-approved solutions to interface the two new bays to the legacy substation systems, ABB will be able to cut the delivery time for this element by 50 percent
ABB has already commenced design work, and the project is due for completion in October 2007.
