FITNESS

Project Objectives

• Digital Communications - Digital substations are designed with digital communications over fibre optic links instead of analogue signals over copper wires from switchyard to control building. The method relies on the recent International Electrotechnical Commission (IEC) 61850 9 2 ‘Process Bus’ standard for publishing digital SVs. The project trials the fitness-for-purpose of the standard and interoperability of products and integrated systems designed to this standard.
• Measurement - The process bus standard enables integration of smaller, lighter and higher quality sensors. The project is intended to prove that NCITs can be integrated with protection, monitoring and control, and that the data quality is sufficient to fulfil the functions of multiple conventional transformers, while reducing footprint and using environmentally benign materials. Trials include substation NCITs fulfilling protection needs (with a voltage NCIT released in 2015), novel distributed sensors applicable to hybrid overhead/underground lines. It has been trialled by remote and local measurements integrated using IEC 61850 9-2,and conventional transformers via merging units to achieve a practical roadmap for introducing the process bus architecture.
• Protection - With only digital communications and no analogue hardwiring, protection devices are smaller and can be replaced or reconfigured without any changes to wiring in the switchyard, avoiding circuit outages. The reliability and availability of protection in the new architecture in a live substation is a key outcome, as is the interoperability between multi-vendor protections based on IEC 61850-8-1 and 9-2 standards.
• Control - Substation control processes applied in the IEC 61850-8-1 based substation design.
• Substation management - The project intends to prove that multi-vendor equipment is interoperable and can be managed in an integrated system and is cyber secure.

The Benefits

• Lower substation build and modernisation cost. There will be a 10% reduction of substation new-build and replacement costs.
• Reduced outage time and constraints.
• Improved safety for both our customers and members of staff.
• Reduced environmental impact. FITNESS will represent carbon savings through reduction in constraints for the connection of renewable generation and the reduced use of copper in substations.
• Improved customer service as FITNESS will lead to a 4-5% reduction of constraint payments through reduced outage requirements.
• Greater operational flexibility leading to more efficient use of assets.
