GB/T 15945-1995
AbolishedQuality of electric energy supply--Permissible deviation of frequency for power system
电能质量 电力系统频率允许偏差
Application Summary AI generated
This standard specifies the permissible deviation range of power system frequency under normal operating conditions, typically allowing a deviation of ±0.2 Hz for systems with a nominal frequency of 50 Hz. It is applied by power grid operators, electrical equipment manufacturers, and energy regulators in China to ensure the stability and quality of electric energy supply across generation, transmission, and distribution networks. The standard is used in testing and compliance verification for grid-connected equipment and industrial power systems to prevent frequency-related performance degradation or damage.
