Design of a novel wide-area backup protection system

With the fast development of communication technology, some of the functions of power security defense system in China are promising to be enhanced. The proposal is to add an intelligent analyzing and controlling function in key process of protection functionality. Therefore, a novel wide-area backup protection system is reported in this paper. The proposed system comprises a master system and several local units. The system is arranged as three layers. Connected together via fiber-optic communication links, these devices can process intelligent algorithms based on data collected locally. The architecture and algorithm of the system are also introduced. The protection system is co-simulated using EMTP and NS2. The data generated by EMTP are then used in a program to validate the performance of the proposed technique regarding the speed of response, computational burden and reliability. Numerical simulation results corroborate the availability and superior performance of the proposed scheme
