System Integrity Protection Schemes - SIPS

Society's need of electric power transfer capacity, with long lead time for new lines, result in an increased utilisation of existing infrastructure and thus decreased margins in the electric power system. System Integrity Protection Schemes enable maintaining secure operation while increasing capacity for given circumstances.

The transformation of the energy system, together with the increased demand of electricity through electrification of industry and transport, brings significant challenges for operation and planning of the power system. 

RISE Electric Power System actively work with various solutions to support an increased transfer capacity in the power system while maintaining the operational security in a system with decreasing margins. 

System Integrity Protection Schemes - SIPS - covers automatic solutions to prevent disturbances in the power system and can be utilised for various means during normal operation as well as for alert and emergency operation. The aim of a SIPS is to secure the functionality of the power system, in contrast to conventional component protection which are designed for personal safety and protection of equipment. 

The expression System Integrity Protection Schemes (or SIPS) can be seen as an umbrella of various automatic solutions, where different naming conventions are used around the world. Common expressions include: Special Protection Schemes (SPS), System Protection Schemes (SPS), and Remedial Action Schemes (RAS). 

RISE has experience R&D projects, publications, public presentations, and courses in the area, such as:
