This paper presents a new technique for the protection of power transmission systems by using the global positioning system (GPS) and fault generated transients, the integrated positional protection technique. The technique is based on the detection and processing of fault generated high frequency transient signals, in which a centralized protection relay provides the protection of multiple transmission...
This paper presents an integrated boundary protection scheme for power transmission line systems. The scheme combines the latest developments in two areas of power system protection, the transient based protection and the integrated protection. In the proposed scheme, an integrated relay based on boundary protection principle installed at a substation is responsible for the protection of all transmission...
This paper presents a new integrated protection scheme based on distance protection technique. An integrated protection relay is installed at a substation and interfaced to every line through the CTs and busbar VT. The relay is also interfaced to the substation communication network which is communicated with all neighboring substations. The directional detection, phase selection and adaptive distance...
