It is mainly used for converter manufacturers or testing institutions to provide a test platform for testing photovoltaic inverters, wind power converters and energy storage converters. It can not only use the basic parameters of the power grid to simulate the power grid environment, but also provide low voltage ride through performance. In addition to the test unit for grid-connected equipment, it can also provide a comprehensive technical support for the product technology research and development of various converter manufacturers, product factory testing, product quality control and other important links.
We are looking for companies with knowledge of the following requirements:
① The voltage level is 35kV, compatible with 10kV;
② The capacity of a single module is 6MW, which can meet the maximum parallel operation of three modules;
③ Harmonic output can generate 2-25th harmonic. The total harmonic distortion rate of voltage under combined harmonic state (10kV is 4%, 35kV is 3%), and the time is not less than 10min;
④ Rapidly respond to the voltage of 10-20ms from low to high or from high to low.
