China Southern Power Grid Guangdong Company recently announced that the intelligent inspection robot developed by it has been put into use, which is expected to realize 24-hour monitoring of substations, which will improve the intelligent level of the power system. The first robot put into use has started to "work" at the Yunfu 500 kV Wolong Substation of Guangdong Power Grid on November 4.
Yang Yingyi, head of the artificial intelligence technology team of the Robotics Division of China Southern Power Grid Guangdong Energy Technology Co., Ltd., said that as long as the inspection points and inspection routes are pre-set, the inspection tasks are issued in the main control room with one click, and the robot will automatically carry out the relevant routes. Detection and data reading replace the traditional manual inspection.
Inspection is an important guarantee for the safety of substation operation, which is divided into routine inspection and special inspection. Regular inspections range from once a month or once a quarter; while special inspections are set up with more frequent cycles according to specific needs, such as inspections during special power supply periods that require once a day. A substation involves more than 1,000 inspection points, and it usually takes two workers six or seven man-hours to complete, which is time-consuming and labor-intensive.
"With the rapid development of the economy, the scale of the power grid is getting larger and larger, the number of power transmission and transformation equipment is also increasing, and the contradiction between inspection needs and manpower is becoming more and more prominent. How to improve the level of intelligence and reduce manpower input becomes the A new challenge to ensure the security of power supply." Yang Yingyi said.
In recent years, robots have been introduced into the field of electric power inspection, replacing manual work to complete part of the automated inspection work. However, the traditional image recognition method for meter recognition is affected by factors such as complex background and light conditions, and the detection and reading accuracy is low.
"The newly developed intelligent inspection robot uses AI algorithms to greatly improve the accuracy of equipment image recognition. Because robot inspection is less limited by time, weather and other factors, it makes it possible for substation robots to monitor 24 hours a day." Yang Yingyi said ,
Yang Yingyi believes that the promotion, application and empowerment of intelligent inspection robots can effectively promote the unmanned development of substation inspection. In the future, intelligent robots will continue to be applied to transmission line inspections, etc., to promote the intelligentization of power inspections, which will also help improve the level of power security in the Guangdong-Hong Kong-Macao Greater Bay Area.
