Application of On-Line Monitoring Technologies for UHV AC Transmission Lines

As the first practical 1 000 kV AC power transmission demonstration pilot project in China, the 1 000 kV AC power transmission project from Southeast Shanxi via Nanyang to Jingmen possesses such features as high voltage grade, huge transmission capacity and long transmission distance, thus the real-time on-line monitoring is a necessary measure to ensure its secure, stable and reliable operation. In this paper the current on-line monitoring technologies for exiting transmission lines, including the monitoring of transmission line ice-coating, conductor windage yaw, tower inclination, aeolian vibration of conductor and conductor galloping, are analyzed. The basic requirements and range of applying on-line monitoring technologies in UHV AC transmission lines are suggested and the functional requirement of on-line monitoring management platform are put forward.
