摘要
当前杆塔形变及导线舞动幅值监测方法未考虑风压与频率等环境条件,导线幅值振动频率不稳定,监测结果与实际值存在误差。提出一种基于微波干涉技术的杆塔形变及导线舞动幅值监测方法,采用微波干涉技术监测杆塔形变及导线舞动幅值,根据微波干涉技术原理与计算方法,得出杆塔形变量及导线舞动幅值信息,利用计算参数值分析在风压与频率等环境条件因素对杆塔形变及导线舞动幅值预测的影响,比较舞动频率与常规频率,利用比较结果实现导线预测,通过影响形变因素系数,得到微波干涉技术下导线舞动的幅值,实现导线舞动监测。实验结果表明,设计方法能够精准地监测杆塔形变量和导线舞动幅值。
Current monitoring methods for tower deformation and wire galloping amplitude do not consider environmental conditions such as wind pressure and frequency. The vibration frequency of wire amplitude is unstable, and there is an error between the monitoring result and the actual value. A monitoring method of tower deformation and conductor galloping amplitude based on microwave interference technology is proposed. The tower deformation and conductor galloping amplitude were monitored by microwave interference technology. According to the principle and calculation method of microwave interference technology, the information of tower shape variable and conductor galloping amplitude was obtained. The influence of wind pressure, frequency and other environmental factors on tower deformation and conductor galloping was analyzed by using the calculation parameters. Comparing the galloping frequency with the conventional frequency, used the comparison results to achieve wire prediction, through the influence of deformation factor coefficient, got the amplitude of wire galloping under microwave interference technology,realized wire galloping monitoring. The experimental results show that the design method can accurately monitor the tower shape variables and conductor galloping amplitude.
