【摘要】：为避免导线舞动扭转导致计算出的相对位移与实际运动偏差,设计了基于惯性传感器的导线舞动监测系统,对系统中的导线舞动无线监测传感器、导线舞动状态监测装置(CMD)、状态监测代理(CMA)等部分进行了硬件设计和舞动定位算法设计。利用惯性传感器设计,既考虑了导线自激振荡引起的舞动,也考虑了导线扭转运动引起的舞动。搭建了模拟导线舞动的测试平台,对系统可行性进行了测试,并对采用加速度传感器和惯性传感器2种方法进行比较,通过模拟实验结果表明:系统可有效对舞动进行监测,仅采用加速度传感器测量和计算的位移偏大,而利用惯性传感器测量和计算的位移更精确。此系统已在贵州电网山麻I回220 kV线路安装,目前运行良好。
[Abstract]:In order to avoid the deviation between the calculated relative displacement and the actual motion caused by the wire galloping torsion, a traverse galloping monitoring system based on inertial sensor is designed, and the wire galloping wireless monitoring sensor in the system is designed. The hardware design and the algorithm design of the galloping location algorithm are carried out in the part of the wire galloping state monitoring device (CMD) and the condition monitoring agent (CMA). The design of the inertial sensor not only takes into account the galloping caused by the self-excited oscillation of the conductor, but also makes use of the design of the inertial sensor. Also considering the galloping caused by the torsional motion of conductors, the test platform of simulating conductor galloping is built, the feasibility of the system is tested, and the acceleration sensor and inertial sensor are compared. The simulation results show that the system can effectively monitor the galloping, and only the displacement measured and calculated by the acceleration sensor is too large. The displacement measured and calculated by the inertial sensor is more accurate. The system has been installed on the 220 kV line of Shanma I in Guizhou Power Grid and is running well at present.
