Modern networks demand flexible protection solutions and services. Centralized protection and control (CPC) concept isn’t new, but advances in technology and standards make it feasible for modern substations. Flexible CPC solutions can be deployed in different architectures. Main benefits from the solutions are increased flexibility and performance reducing lifecycle costs.

This paper discusses the need and reasons for the Centralised Protection Concept (CPC) and the problems resolved by these CPC solutions. It explains the principles and technology enabling the concept and covers the ABB story behind the development of CPC, testing issues and site trials with Utility partners through to delivered solutions.

We also discuss other possible functions & applications potentially available using CPC. Finally, we think about the future possible benefits and flexibility, including AI, dynamic protection and other bespoke individual customer needs.

 Key Learning Points: 

  • What is the Centralised Protection concept (CPC) & why?
  • How does CPC work?
