| Abstract: | This paper indicates the problem in set of protection in rural power grid,analyses the trend and brings forward the important of optical fiber differential protection in rural power grid.It gives a detailed explanation on the implementation procedure and solution of optical fiber differential protection. For some problems about data transmitting and channel of differential current protection, a new method to solve them is pointed out. If to realize sampling synchronization by using Newton interpolation ,the... |
