High Voltage Cascade Energy Storage Converter Standard

This standard specifies functional requirements for high voltage cascade energy storage converters, including start-stop, power control, alarm and protection, insulation resistance detection, communication, operating information monitoring, statistics, data display and storage, as well as electrical and safety performance. It covers normal working conditions, appearance and protection level, electromagnetic compatibility, auxiliary systems, inspection rules, marking, packaging, transportation and storage. Applicable to grid-connected converters with electrochemical cells as energy storage carriers and AC port voltages of 6kV, 10kV, and 35kV. The document references various GB/T and DL/T standards for power quality, electromagnetic compatibility, and environmental conditions. Key features include continuous smooth regulation of active and reactive power, fault diagnosis with sound/light alarms, and DC port insulation resistance detection. The standard ensures reliable operation under specified environmental and electrical conditions, with protection levels of IP20 for indoor and IP54 for outdoor units.
