    摘要:

    输电线路风偏舞动的爆发频率较高,严重影响电力系统的正常稳定运行,给国民经济带来重大损失问题,因此,输电线路舞动实时在线监测一直是该领域的研究热点。从输电线路舞动成因出发,讨论输电线路舞动在线监测技术及系统性能,分析常用的舞动在线监测方法、以及相关研究及其存在的问题,并对目前输电线舞动在线监测技术的难点进行了总结。提出了“MEMS振动传感器+BD差分定位”融合监测方法,以WSN/GPRS/BD三网融合通信组网模式,建立基于北斗通信的天空地一体化大跨越输电线风偏舞动实时在线监测网络化平台以实现输电线舞动的实时监测,对开展输电线路舞动实时在线监测研究具有实际指导意义。

    Abstract:

    The outbreak frequency of the galloping caused by wind deflection of transmission lines is relatively high, which seriously affects the normal and stable operation of the power system and brings significant losses to the national economy. Therefore, the real-time online monitoring of the galloping of transmission lines has always been a research hotspot in this field. Starting from the causes of the galloping of transmission lines, this paper discusses the online monitoring technology and system performance of the galloping of transmission lines, analyzes the commonly used online monitoring methods for galloping, related research and existing problems, and summarizes the difficulties of the current online monitoring technology for the galloping of transmission lines. A fusion monitoring method of "MEMS vibration sensor + BD differential positioning" is proposed. With the communication networking mode of the integration of WSN/GPRS/BD three networks, a real-time online monitoring network platform for the galloping caused by wind deflection of large crossing transmission lines with the integration of sky, ground and space based on Beidou communication is established to achieve the real-time monitoring of the galloping of transmission lines, which has practical guiding significance for carrying out the research on the real-time online monitoring of the galloping of transmission lines.
