Research Background

As the progress and development of the time and technology, the ratio of new energy power generation has continually increased,distributed power generation and usage brings a more complex control system requirement,especially the inverter system in power generation part.Inverter system research needs connected with a complex micro-grid or a massive grid,doing a series power electronic algorithm and function test .Test the inverter system by using physical equipment require a large investment in resource,space,time,and cannot do a flexible test.These disadvantage above not conducive with detailed,efficient,reliable and safe R&D.Using Real-Time simulation test inverter control algorithm and system certify,reduced investment and time costs.
