摘　　要：随着超高压、特高压电网的全面建设,输电线路振动成为威胁电网安全的重要因素之一。选择一种安全、高效的振动测量方法,可对解决和控制线路振动起到重要作用。分析了输电线路的振动特性,介绍了几种常见的振动测量方法并分析比较了其优缺点,提出了一种全新的光电式振动测量方法。该方法可提高测量精度,减少安全隐患。As the overall building of EHV and UHV grid, the vibration occurred on transmission line has become a threat to the security of the grid. A safe and efficient measurements method plays an important role in resolving and restricting the vibration. This paper analyzes the vibration characteristics of the transmission line, introduces several common measuring methods for the vibration, and compares their advantages ＆ disadvantages. Finally, the paper proposes a new measurement method using photoelectric technology which can improve measuring accuracy and eliminate safety hidden trouble.
