基于传感器技术的导线舞动状态监测评估系统

导线舞动造成的危害一般主要是由于舞动幅值过大,造成相间气隙不够引起相间闪络造成。针对导线舞动的特点,基于传感器技术和虚拟仪器技术,开发了导线舞动状态监测评估系统。舞动监测终端实时测量现场舞动数据,经过单片机处理,通过GPRS无线传输模块发送至上位机完成图形化显示,利用上位机软件搭建的导线舞动状态评估模型实现导线舞动状态的评估。在实验室搭建了导线舞动模拟平台,引入舞动摆角,进行了运行试验。试验结果表明:该系统能有效监测导线舞动状态变化,较准确地完成导线舞动状态评估。

System for monitoring and assessment of conductors galloping based on sensor technology

The damages caused by conductors galloping are usually due to too large galloping amplitudes,causing interphase flashover.For the characteristics of conductors galloping,the system for monitoring and assessment of conductor galloping is developed based on the technology of sensors and virtual instrument.The conductors galloping data is adopted by the galloping monitoring terminal,the signals are processed by SCM,and the data are transmitted to the host computer by GPRS module to complete figurative display,the evaluation of galloping state is achieved by the model for assessment of conductor galloping.The simulating test platform for conductors galloping is built in the laboratory,the galloping swing angle is introduced,and the system running test is carried out,the results show that the system can achieve effective monitoring for the state of transmission lines galloping,it can accurately assess the state of conductors galloping.
