Scope
GB/T 44933-2024 is the English-translated version of 电力储能用飞轮储能系统技术规范.
GB/T 44933-2024 is the Chinese national standard covering the flywheel plant that stores grid energy as rotation rather than chemistry — the overall requirements and the system architecture that ties the flywheel units, the converter and the management system together, the operating environment, the functions and the performance the system has to show, the auxiliary system, and the on-site test methods, which apply from 200 kW of rated discharge power upwards on an AC-connected installation. It works with the unit-level standard GB/T 44934-2024, which covers the flywheel storage unit itself. First edition, under the China Electricity Council. In force from 1 July 2025. Issued on 31 December 2024, it has been in force since 1 July 2025.
