In a significant advancement for China's energy infrastructure, China Southern Power Grid Co., Ltd. has announced the official deployment of the country's inaugural large-scale pumped storage model, developed in-house. This development signifies that nearly one-fifth of China's pumped storage capacity will now be governed by advanced intelligent systems, bolstering the grid's peak load regulation and energy storage capabilities.
The National Energy Administration's "Medium and Long-Term Development Plan for Pumped Storage(2021—2035)"has targeted an installed capacity of approximately 120 million kilowatts for pumped storage by 2030.Pumped storage power stations are known for their massive scale, multitude of mechanical and electrical equipment, and intricate system structures. For instance, the widely utilized 300,000-kilowatt units comprise four major categories and 20 critical equipment components. Traditional operation and maintenance models involve over 400 daily inspection items, demanding a substantial workforce.
This new large-scale model is equipped with a comprehensive knowledge base for the maintenance of pumped storage unit equipment. It can intelligently interpret verbal instructions from technicians, proactively gather equipment-related information and data, and autonomously manipulate analytical tools. Integrated into China's third-generation pumped storage artificial intelligence data analysis platform, the model has increased operational efficiency by 50%.It enables deep intelligent management of equipment across seven pumped storage power stations with a cumulative installation scale of 10.28 million kilowatts. The platform features condition warning analysis, online asset management, and the development of maintenance strategies.
Leveraging real-time data from 420,000 monitoring points and the autonomous invocation of 9,000 algorithms, the proportion of intelligent inspections has been significantly enhanced. This ensures that pumped storage power stations are always ready to meet the demands of grid dispatch. This technological leap positions China at the forefront of intelligent energy management, supporting the nation's commitment to achieving its "dual carbon" goals. (Science and Technology Daily)
