Abstract :
Fault generated transient signals can undoubtedly be employed to achieve ultra-high-speeds in transmission line protection. Even though such transient based schemes can quickly detect a faulty state on the power system, they face several challenges. Firstly, they have inherent reliability problems and secondly, it is difficult to implement them as a real-time product due to their excessive demand for high speed signal acquisition and processing. This paper examines the theoretical aspects and design procedure of a reliable, high speed protection scheme based on fault generated travelling wave information.
