Goldwind has developed and built the first large-scale wind turbine six-degree-of-freedom test bench in China, filling the gap in the industry. Promote the development of new technologies, accelerate design iteration and optimization, and provide guarantee for the high-quality development of the industry.

Institute of Electrical Engineering, Chinese Academy of Sciences (IEECAS) has designed the world’s first technical verification platform for offshore DC system, which is in the high power laboratory of IEECAS, Beijing. The DC voltage range of the platform is ±5kV~±30kV and the rated power is 500kW. The key technologies include reliable operation control strategy with a wide voltage range, multi-objective optimization of topology and control parameters under complex constraints, and multi-level and efficient coupling simulation technology of the platform. IEECAS also has developed the SiC MOSFET based DC/DC converter. The rated power of the unit is 500kW and the rated output voltage is ±10kV. The measured max. efficiency of the unit is 99.6%.

IEECAS has set up a two-site online monitoring platform which could provide seven water quality parameters (including water temperature, pH, ammonia nitrogen, dissolved oxygen, turbidity, chlorophyll, and conductivity) with a transmission frequency of 0.5 h/time for the Floating Photovoltaic (FPV) power station. At present, more than 2,800 data items have been received, and an empirical database on the impact of FPV on the water environment has been initially constructed.
