Fujitsu will leverage Chugoku Electric Power T & D ' s intellectual property to launch an advanced power grid operation and maintenance support service for power transmission and distribution companies. This service will enable safe and maximum connection and utilisation of renewable energy in the power grid. and accurately assess the condition of transmission facilities.

Fujitsu has developed technology to acquire and analyse vibration data across all spans of transmission lines using optical fibre sensing technology with a single measuring device, as well as a technology platform for data management and AI analysis. To apply these technologies in a practical operational setting for power transmission and distribution companies, Fujitsu and Chugoku Electric Power T & D have conducted verification tests rating technology and expertise in power transmission facility operation and maintenance, cultivated through verification tests and practical operations, with Fujitsu ' s optical fibre sensing, data analysis and AI technologies. It acquires vibration data from optical fibres laid along transmission lines and uses environmental data, such as wind conditions around the transmission lines, derived from this vibration data, to calculate the available transmission capacity according to the real-time facility status. Furthermore, by

As the adoption of renewable energy continues to expand, power transmission and distribution companies are working to maximise the use of existing power transmission facilities while maintaining stable operation of the power system. The capacity of transmission lines for safe power transmission varies with environmental conditions like temperature and wind speed. Traditionally, to protect transmission facilities, operations have been based on the transmission capacity under the worst-case conditions. However, dynamic line rating technology, which adjusts transmission capacity based on real-time environmental conditions, is now recognised as a key method for effectively utilising transmission capacity while making the most of existing facilities.

Furthermore, there are concerns that conventional human-dependent maintenance operations, such as inspection and patrolling of power transmission facilities, will face operational challenges in the future due to a shrinking workforce. To address these challenges, initiatives are progressing to utilise digital technologies and drones to efficiently since September 2021, focusing on expanding renewable energy adoption and enhancing power transmission facility maintenance operations.

The service integrates Chugoku Electric Power T & D ' s intellectual property, including its dynamic line training and inferring with AI using the acquired data, it becomes possible to predict future wind conditions around transmission lines and transmission capacity. These series of data acquisition, conversion and prediction functions will be provided as the basic functions of this service. n
