Abstract:

The two standards Low-voltage Reactive Power Compensation Assemblies (GB/T 15576—2020) and Low Voltage Hybrid Dynamic Reactive Power Compensation Assemblies (T/CPSS 1001—2019) was successively issued,which have the targeted technical requirements and detection provisions for the low voltage switchgear assembly reactive power compensation devices.The main differences of the two standards are studied and analyzed from the aspects of the standard application scope,terms and definitions,device classification,service conditions,basic protection,control and protection functions,performance test,electromagnetic compatibility test,ambient temperature performance test,etc.,which can provide the reference for relevant personnel.

Key words: reactive power compensation, hybrid dynamic reactive power compensation, dynamic response time, harmonic filtering, standard difference
