TLDR
The use of digital techniques to adapt transmission system protection and control to real-time power system changes is investigated and adaptive strategies that minimize the compromises required and thereby optimize system performance are presented.Abstract:
The use of digital techniques to adapt transmission system protection and control to real-time power system changes is investigated. The discussion covers transmission system protection philosophy, transmission line protection, relay settings, transformer protection, and automatic reclosing. The tradeoff between dependability and security is examined, as well as the various conflicting criteria embodied in transmission line protection. Adaptive strategies that minimize the compromises required and thereby optimize system performance are presented. >read more
