| Abstract: | Global Positioning System (GPS) has become the public high technology resources for the whole world. Its Precise time transfer and synchronization technique can find wide applications in electrical power system. This paper describes the principle of GPS time transfer and synchronization at first, then presents the configuration of new type current differential protection which use GPS to carry out synchronized sampling. At the end, the paper does the analysis and evaluation to the new synchronized sampling and teh differential protection scheme according to the preliminary testing results. |
