Recently, the 13.6MW offshore wind turbine successfully rolled off the production line in Fujian Three Gorges Offshore Wind Power International Industrial Park, which is the largest impeller diameter of 252 meters in the world, the highest wind energy conversion efficiency of units of the same capacity, and the largest single capacity of wind turbines in the Asia-Pacific region. It is worth mentioning that Shenzhen Huichuan Technology Co., LTD. (referred to as “Huichuan Technology”) provided the PD802 Plus-80A high-power variable pitch drive and MD810 yaw inverter for the unit, which helped the world’s largest impeller diameter fan successfully roll off the line, and at the same time escorted the stable operation of the wind turbine throughout the life cycle.

Under the “dual carbon” goal, offshore wind power, as a potential clean energy, has the advantages of large resource potential, good wind energy conditions, fewer limiting factors, and close load, which will play an important role in optimizing China’s energy structure and promoting the development and utilization of clean energy such as wind power. In recent years, with the innovation of offshore wind power technology and the drive of affordable Internet access, the development of offshore wind power in China has shown a trend of “far-reaching sea” and “large-scale”, and the large-scale wind turbine has become one of the effective ways to reduce the cost of KWH in wind farms.

The launch of the 13.6MW unit marks that the R&D and manufacturing capacity of China’s offshore wind power large-capacity units has entered the world’s advanced ranks, and the power generation performance and reliability of China’s offshore wind power products have been pushed to a new level.

In order to meet the needs of “large-scale” and “far-reaching sea” of offshore wind turbines, Huichuan Technology released the PD802 Plus 80A high-power variable power driver as early as October last year, filling the product gap of domestic brands in high-power drivers.

Huichuan Technology PD802 Plus high power variable pitch driver

PD802 Plus rated output current 80A, overload current 300A/3S, high overload capacity to meet the wind conditions under the extreme load application scenario, C5M anti-corrosion class design to meet the Marine application scenario. The PD802 Plus variable pitch driver standard bus communication interface is suitable for dual-drive solutions, which can meet the application requirements of 6MW to 20MW units. The drive not only breaks through the 15MW+ class large offshore wind turbine variable pitch drive technology, but also becomes the first product in China to meet the drive PLd level and system PLe level safety certification, which can help customers reduce costs and increase efficiency.

Huichuan Technology MD810 yaw inverter

In addition, Huichuan technology MD810 yaw inverter adopts common bus architecture, which can effectively improve power efficiency, achieve 5%~30% energy saving, modular product design, smaller volume, easier installation and maintenance. The MD810 intelligent frequency conversion yaw scheme has the function of backlash compensation and redundancy control, which can improve the reliability and typhoon resistance of offshore wind turbines.

In the future, Huichuan Technology will continue to contribute wisdom for offshore wind power to the far-reaching sea, reduce costs and increase efficiency, adhere to innovation-driven, and practice the “double carbon” goal.
