| Abstract: | An idea about structure of unified pilot protection system is proposed.By virtue of optical fiber communication system,it can obtain multi-information such as sample values of analog current,voltage and all kinds of digital information.With these information,it can not only accomplish many criterions in one protection system to enhance the performances of pilot protection system,but also achieve some other auxiliary functions such as re-closure coordination,line parameters calculation and so on.Based on the... |
