Damping Characteristics of Large-section Conductors for UHV DC Projects
摘要
Abstract
Since Jinping-Sunan ±800 kV DC power transmission project had been completed, application of 900 mm2 and above large-section conductors started in UHV DC transmission line in our country. And since Lingzhou-Shaoxing ±800 kV UHV DC project had been completed, 1 250 mm2 large-section conductors were widely used. In order to master the damping characteristics of large-section conductors in Aeolian vibration condition, self-damping characteristics of a series of 1 250 mm2 large-section conductors are tested and analyzed by Aeolian vibration simulation test. The self-damping analytical expressions, power characteristics and frequency response characteristics of five kinds of 1 250 mm2 conductors are obtained. And the self-damping characteristics of 1 250 mm2 shaped wire, 1 250 mm2 round wire, 1 250 mm2 conductor and 1 000 mm2 conductor are analyzed and compared.关键词
