The second part of our Microgrid Applications webinar, including a demo.
Off-shore wind farms are one of important energy sources that realize the carbon neutral before 2050 in Japan. Since the depth of sea around Japan is more that 50m, facilities of transmission systems for off-shore wind farms have to be installed on floating platforms. Middle frequency (500Hz) convertor is a promising equipment that reduce the weight and volume of transformer used for substation on the floating platform. The MMC is a solution that can operate at 500Hz with less switching loss. It however requires much system analysis to develop and tune the control system. Real time simulator is a useful tool for small academic laboratories to study on the MMC. It saves risks of hardware troubles caused by mal operation of control system. An example of studies, such as fundamental operation of scaled model (200V, 1A) of MMC convertor, real time simulation for tuning of control system, and harmonics study in our laboratory will be introduced in the presentation.
