G.P.S. use in EHV and HVDC Transmission Line Protection
Journal Title: The International Journal of Technological Exploration and Learning - Year 2014, Vol 3, Issue 2
Abstract
This paper presents a new technique G.P.S. (global positioning system) for EHV and HVDC transmission line protection. In this scheme, the relay restrains a fault transient detection system relay together with a communication system such as SCADA system. Relays are located at each bus bar in a transmission line network. These relay detect the fault and generated high transient signals and trace the time instant corresponding to different fault occurs at bus bar and it generate initial travelling wave. Communication system SCADA is use to transmit and received digital signal of the local information and also from relays in the system .this paper provide how to use global positioning system for fast detection of the fault and solved it.
