| Abstract: | This paper presents a new synchronizing method of data sampling for digital current differential protection of transmission lines. This method based on global positioning system (GPS) not only gives high accuracy of Synohronizing, but also simplifies the software of the protection. The new method may bring a great technical progress to current differential protection and improve its function.This paper first introduces the GPS general situation, then describes in some detail the receiving of GPS time information and the principle of new Synchronizing sampling. At last, the basic designing scheme of this new current differential protection is given. |
