According to a report by Chinanews Guangxi on January 22, Guangxi Power Grid Corporation released a large model of artificial intelligence for power transmission. The large model is based on the "big watt" base of China Southern Power Grid, jointly developed by Guangxi Power Grid Corporation and China Southern Power Grid Artificial Intelligence Technology Co., Ltd., and is the first online application model of the production environment in the domestic power industry. According to Xuan Liang, general manager of the production technology department of China Southern Power Grid Guangxi Power Grid Company, compared with the traditional small model, the transmission artificial intelligence large model has better performance in terms of accuracy, generalization ability, and recognition efficiency. First, the number of parameters has increased from millions to 100 million, and secondly, the efficiency of defect identification has been increased by 5 times, and the accuracy has been increased by 15%, which can more accurately express the type and location of defect hazards, solve the problem of model fragmentation, and better deal with defects in unseen power business scenarios.
