1000kV淮南—上海输变电工程同塔双回钢管塔风振控制
|
摘要
以1000kV淮南—上海(皖电东送)输变电工程同塔双回钢管塔为研究对象,对风荷载作用下杆塔的整体振动以及局部钢管杆件的涡激振动的控制措施,分别采用数值仿真和风洞试验进行了研究。针对整塔的风振,提出采用粘弹性阻尼器并联于钢管主材外侧控制弯曲振动、调谐质量阻尼器置于横担端部控制扭转振动的新型联合控制方案;针对局部钢管杆件的横风向涡激振动,提出采用螺旋形扰流线的控制方案;并给出控制装置的关键技术参数的设计方法。控制措施易于工程应用,在一定的参数下,塔顶处顺风向位移和加速度响应可降低30%,杆件横风向振动基本消失,钢管塔的这2类风振得到有效抑制。
Taking the 1 000 kV double-circuit transmission lines on the same tower from South Anhui province to Shanghai (Anhui-to-east power transfer) as research background, the wind-induced vibration suppression of integrated tower and local tubular member of UHV steel tubular tower were studied respectively with numerical simulation and wind tunnel experiment. The solution combined viscoelastic dampers with tuned mass dampers (TMD), where viscoelastic dampers in parallel with the tower leg and located at its outer was used to control bending vibration and TMD located at cross arm to control torsional vibration, was proposed for the vibration control of integrated tower. And the measurement of attaching flow disturbing spiral wire on member was presented for vortex-induced vibration suppression of local tubular member. Design methods for main parameters of the vibration control devices were also put forward. Results of simulation and experiment indicate that the above vibration suppression methods are effective in practical project. Under certain parameters, vibration responses of tower top along wind direction can be reduced more than 30%, and vibration of tubular member transverse to wind direction disappear almost completely.
