With the arrival of winter, the power grid has entered an intense stage of anti-icing and power protection. Ice protection is a protracted war, in recent years, by the global warming, subtropical high pressure location changes and other impacts, transmission lines covered with ice dance phenomenon occurs from time to time.
When the wind speed is in a certain range (generally in 4 - 20m/s), and the wind direction and the line direction angle between 45° - 90°, the conductor is prone to dance, like the "hundred miles of wind area" and "thirty miles of wind area" in Xinjiang, it can be imagined that the overlying ice dancing Energy is huge, and long duration; In addition, in the mountainous areas, the wind direction and wind speed may change instantly due to the ups and downs of the terrain; In the coastal areas, the path and intensity of typhoons and other extreme weather is also uncertain, which can easily lead to damage to the conductor fittings, line flashing tripped, tower instability collapse and other accidents, a serious threat to the safe and stable operation of the power grid. Based on this, our company launched the Transmission line conductor dance Monitoring and Early Warning SystemDX-WPS100-WD is designed to strengthen the level of anti-icing and anti-dancing of transmission lines to ensure the safe and stable operation of power grids in winter.
Power line conductor dance monitoring and early warning system integrates advanced sensor technology and data analysis algorithms, which can monitor the conductor movement status in real time, including conductor displacement, dance amplitude, dance frequency, acceleration, inclination angle, micro-meteorology, etc., and synchronize the data in real time to the monitoring center platform by using the 4G/5G/GPRS/CDMA wireless communication module, which combines the data modeling to diagnose the abnormal information in time, and send SMS messages to the mobile terminal of the operation and maintenance personnel or display on the big screen to realize the real-time sensing of transmission line dance status. The platform combined with data modeling, timely diagnosis of abnormal information, to the operation and maintenance personnel's cell phone terminal to send SMS, push APP messages, or in the monitoring center of the large screen display, to achieve real-time perception of transmission line dance status. ;
Specifically through the contact measurement method, for example, multiple dance sensors are installed on the wires, and real-time parameters such as dance amplitude (horizontal and vertical), dance frequency, as well as acceleration and displacement of the wires are collected at each monitoring point, and sent to the monitoring base station through 2.4GHz wireless communication.
