基于智能间隔棒的输电线风偏舞动监测技术
Monitoring technology of wind deviation of transmission line based on power line intelligent spacing bar
摘要
Abstract
Aiming at the problems of complex installation,high power supply and maintenance costs of existing transmission line wind deflection/galloping monitoring terminals,this paper proposes a wireless intelligent monitoring scheme based on spacer dampers:MEMS(micro-electro-mechanical-system)three-axis inertial sensors are embedded in the spacer dampers to obtain the three-directional vibration and torsional responses of the conductors;combined with the compressed sensing framework and the orthogonal matching pursuit(orthogonal matching pursuit)reconstruction algorithm,the sparsity of data is utilized and a Gaussian random sensing matrix is adopted to realize the reconstruction of the full-line galloping curves.The simulation and experimental results show that:under the given span condition,the sparsity can be adaptively set with the sampling length;when the observation ratio is 10%to 20%,high reconstruction accuracy can be achieved,which meets the online monitoring needs of long-span lines.This wireless intelligent spacer damper monitoring scheme provides an engineering feasible path for the real-time monitoring and reconstruction of transmission line wind deflection/galloping.关键词
