摘要
介绍了浙江电网一起典型的500 kV同塔双回线路舞动故障事件及其机理分析,对运行和新建的输电线路,提出进行综合抗舞动设计、局部补强分析及实时监测等技术整改措施,对今后避免类似舞动故障的发生具有积极的意义。
This paper puts forward the technical improvement measures for the operating and newly-built transmission lines such as comprehensive anti-galloping design,local reinforcement analysis and real-time monitoring based on the mechanism analysis of the typical galloping fault for 500 kV double circuit on the same tower in Zhejiang power grid.It is of high significance to prevent similar faults in future.
