The Construction and Development of Comprehensive Test Centre Based on Real Transmission Line

Abstract:

Galloping of overhead transmission line is a low-frequency, large amplitude, wind-induced vibrations of both single and bundle of overhead transmission lines, which have been one of the largest threaten for the security and stability of power grid operation. On account of the uncertainty and probability of galloping events happening, most of the study on transmission line galloping had still stayed on simulation or model test, only less of the study were in accordance with the accident records on-site. Several ten years study on conductor galloping had been proved that the laboratory built on real transmission line was the essential foundation and the effective condition for the systemic study on galloping. Comprehensive Test Centre based on Real Transmission Line (CTC for short) is the first laboratory focus on the study of conductor galloping and ice-accretion. whose content of tower type,conductor arrangement and transmission line length, currently have been the most abundant in worldwide. The establishment of the Comprehensive test centre have been very important on promoting the fundamental and systemic study in the relative field. Since the frequent conductor galloping under the condition of natural climate achieved successfully, CTC have developed several essential and valuable scientific projects. In this paper, CTC would be introduced from the aspects of basic facilities configuration, mainly function design and implementation, focal capabilities and some study outcomes at moment.
