GE’s Digital Energy business (GE) will provide series compensation capabilities to three of SP Power Systems Limited’s (Scottish Power) facilities in southern Scotland, helping the utility meet and mitigate today’s highly complex and technical grid challenges.
The utility will be installing series capacitor banks with sub-synchronous resonance (SSR) filters to its substations, increasing the reliability, efficiency and power transfer capabilities of Scottish Power’s 400-kV transmission network.
The updates to Scottish Power’s network will continue to allow power to flow from northern Scotland into England. GE’s series compensation solution enables the broader initiative of the European Union’s target to integrate more than 15 percent renewable power generation into their portfolio mix.
GE and Balfour Beatty Engineering Services (BBES) — a supplier for Scottish Power’s substation equipment — will provide installation, commissioning and maintenance of series compensation banks with SSR filters at Scottish Power’s Moffat (400-kV, 560-MVAr), Gretna (400-kV, 560-MVAr) and Eccles 1 and 2 (400-kilovolt, 442-MVAr each) substations.
These series capacitor banks with SSR filters will provide Scottish Power, part of the Iberdrola Group, a cost-effective method to increase power transfer across its long transmission lines. Working with BBES enabled GE to fulfill and meet local requirements and standards for Scottish Power’s facilities. It also establishes a localized presence in the region that can provide long-term support and maintenance to each of the series capacitor banks as needed.
The four series compensation banks installed by GE will utilize its reliable fuseless capacitor design and will include metal-oxide varistors and triggered air gaps. The scope of the project also includes detailed studies and analysis from GE’s Energy Consulting business for the design and application of the SSR filters. The project is scheduled to be completed in 2015.
