| Abstract: |
| An advanced protection based on digital signal processor (DSP) for HV Power transmission line is introduced. It has two CPUs and the distance relay and zero sequence directional overcurrent relay are its main protections.The applied new intelligent technology in both HW and SW improver its performance greatly. This protection device has compact structure, high reliability and friendly man machine interface.Its prototype for 110 kV has completed. |
