A generalized approach to the protection of modern power systems

This paper describes a knowledge-based system for the analysis and design of the protection a system element or group of elements such as a substation. The structure of the knowledge-based system is based on an object-oriented approach in order to manipulate and reuse the functions and protection algorithms. Given the input requirements, the knowledge-based system will propose a protection system in the form of a generic relay based on an events-and-consequences methodology.
