Smart Grid| Corerain x South China Municipal Power Supply Bureau


The South China Municipal Power Supply Bureau is a power supply enterprise directly under the top 500 power grid group. The company has more than 30 substations, with a transformer capacity of over 4 million KVA and transmission lines with a total length of 1,800 km.

Inefficient and High-risk Patrol Inspection
Inefficient and High-risk Patrol Inspection
Multiple points, long lines and wide areas, cause difficulties of artificial patrol inspection with low efficiency and high risk, and more than 50 average annual accidents.
High Input Cost
High Input Cost
The total length of power transmission lines is 1.59 million km. If calculated at the artificial cost of 20,000 yuan / km, the annual artificial inspection cost exceeds 30 billion yuan.
Low Data Processing Ability
Low Data Processing Ability
It's not possible to carry out real-time image analysis by UAV + artificial inspection mode, fault detection is not timely, and background artificial inspection data is large in volume and can be easily left out.

For the demands for intelligent management of transmission lines, Corerain cooperates with this power grid municipal bureau for the following solutions:

·Develop an emergency repair artificial intelligence computing platform to process data from videos accessed by the existing system through deep learning algorithms.

·Detect the defect of common transmission line components such as bird's nest, insulator, triangular plate, anti-vibration hammer tilt, as well as foreign object, and tower sloping recognition.

·Make real-time detection of helmet and uniform wearing of workers, personnel intrusion, smoke and flame and other safety hazards.

The program successfully builds an AI intelligent analysis platform for transmission lines with patrol inspection of UAV + AI to achieve the following results.Automatic fault recognition and intelligent warning to effectively improve the reliability of transmission line inspection.
Intelligent means to greatly reduce inspection intensity, increase efficiency by 50 times, and save manpower cost by 80%.
