GB/T 39572.1-2020 Bi-directional grid-connected power converters—Part 1:General requirements

Scope

This part of GB/T 39572 specifies the general requirements for grid-connected bidirectional power converters (GCPCs). Grid-connected bidirectional power converters consist of a grid-side inverter connected to an application-side system voltage of no more than AC 1,000 V or DC 1,500 V and having two or more DC ports. In special cases, grid-connected bidirectional power converters may only have one DC port connected to a bidirectional energy storage device. This part includes definitions of terms, specifications, performance, safety, system architecture, and test examples. "System architecture" defines the interaction mode between the inverter and the converter. This part defines the common and general performance requirements for grid-connected bidirectional power converters, which are not affected by the characteristics of individual power generation devices and bidirectional energy storage devices.
This part does not cover uninterruptible power supply systems (UPSs) that fall within the scope of IEC 62040 (all parts). Requirements for internal and external digital communication may be necessary, including interface requirements for communication with distributed energy sources, which will be provided in future parts of GB/T 39572. All EMC requirements are defined with reference to existing IEC standards. This part does not include external communication requirements.
Note: This part does not define control signals from the grid.
