基于真型输电线路试验的双摆防舞器防舞性能评价体系研究

摘要

双摆防舞器在输电线路防舞动方面得到广泛应用,但是其应用效果难以进行评估.本研究以河南省电力公司真型试验基地为依托,对双摆防舞器的使用特点和适用范围进行分析,通过现场试验实现了真型输电线路的舞动模拟,并以试验评价为基础,结合数值模拟仿真技术,建立了试验与仿真相结合的防舞装置综合评价体系.结果表明:该评价体系能较好评估线路舞动特性,可为线路的防舞设计提供技术指导.%The double pendulum damper is widely used in anti-galloping of transmission lines, but its effect is difficult to be assessed. The characteristics and scope of application of double pendulum damper are analyzed based on the real test base of Henan electric power company, the transmission lines galloping is simulated through field experiments, and the anti-galloping comprehensive assessment system combining experimental and simulation means is established on the basis of experimental assessment. The results show that this assessment systemcan well assess the transmission line-galloping characteristics and provide technical guidance for the design of transmission line anti-galloping.
