Description

technical field

[0001] The invention relates to a test platform for a converter, in particular to a test platform for a large energy storage converter. Background technique

[0002] With the development of distributed power generation technology, large-capacity energy storage systems have been more and more widely used. In the energy storage system, the energy storage converter is the key equipment connecting the grid and the battery, as well as the power station and the battery. Therefore, the stable operation of the energy storage converter in the distributed power generation system is very important. In order to ensure the stable operation of the distributed power generation system, it is essential to test the safety, stability, electrical characteristics and protection performance of the energy storage converter. At present, the domestic standard for energy storage converters is only the energy industry standard NB / T31016-2011 "Technical Conditions for Battery Energy St...
