Affected by two rounds of cold wave this year, rain, snow and freezing weather appeared in most of Guizhou, northern Yunnan, northern Guangxi and northern Guangdong, with blizzards in local areas, resulting in a number of ice-affected lines in the operating area of the Southern Power Grid, with more than 900 lines covered with ice at the peak.
Southern Power Grid since January 21 to continue to start the emergency mechanism, scientific anti-icing and anti-icing, scientific and technological ice melting, intelligent patrol, rapid restoration of power, on the reduction of the impact of the disaster, the Southern Power Grid operating areas affected by the user basically within 24 hours to restore power supply. 17:00 on February 23, the Southern Power Grid ice-covered lines have been reduced from more than 900 to more than 300.
Power protection personnel stick to the front line of anti-ice, all kinds of scientific and technological assistants have also been on the field "business". Ice online monitoring system, drones de-icing, de-icing robots, DC ice melting and other ways to continue to carry out ice-covered power lines melt de-icing, to protect the safe and stable operation of the line.
DX-WPS100-FB, also known as Ice Watching Ice Wizard, adopts the combination of solar energy and lithium battery to supply power, which can solve the problem of insufficient function in rainy and snowy weather, and has the function of visualized video monitoring, and at the same time, integrates the micro-meteorological module and tensile force measurement module, which can help the power company to grasp the real-time ice-covering situation of the line and the operation status, and effectively respond to the severe ice and frost weather. Effective response to severe freezing weather.
Transmission line ice-covering online monitoring system uses high-definition cameras, micro-weather sensors and tension sensors to collect real-time on-site video images as well as data such as temperature, humidity, wind direction, wind speed, wire tension value, insulator string tension value, etc., and then uploads them to the monitoring center for comprehensive analysis by 4G/5G/WIFI wireless network. The system has built-in AI ice-covering image recognition algorithm, which can calculate the line ice-covering thickness, and when the ice-covering thickness reaches the warning value, it will automatically push the ice-covering status warning information to the user through the back office, SMS, and small programs, realizing the whole process of "electric power meteorological prediction-visualized ice observation-line tension monitoring-line ice-covering warning" linkage.
