摘要
为提高输电线路在线监测的智能化水平,研究开发了高压架空输电线路视频在线监测系统。该系统由多个线路终端设备和1个线路监控主站构成,具有杆塔和线路通道危险点实时视频监控以及绝缘子污秽、闪络定位、微气候和风偏、线路舞动和覆冰的监测等功能。该系统采用TCP/IP协议的网状网无线宽带专用网络技术实现系统与供电局光纤通信网络的无缝联结;采用数字用户线路技术完成图像信号的传输;采用模块化设计方案和mesh无线应用方案,使系统扩展性良好,配置灵活,容错能力强,速度响应快。该系统在广东电网公司深圳供电局应用,效果良好。
On-line video surveillance system of overhead HV transmission lines is developed in order to enhance the intelligence level of on-line surveillance on transmission lines.The on-line video surveillance system is composed of many line termination equipment and one primary station for line surveillance and it has such functions as real-time video surveillance of hazard points in poles,towers and line channels,as well as surveillance of insulator dirt,flashover location,microclimate and windage yaw,line galloping and icing.This system adopts mesh network technology exclusively for wireless broadband with TCP/IP protocols to enable seamless connection with optical fiber communication networks of power supply bureaus;it also adopts digital subscriber line technology for image signal transmission and adopts modular design scheme and wireless mesh to attain good expansibility,flexible configuration,fault-tolerance and quick response.
