Recently, the 13.6MW offshore wind turbine has successfully rolled off the assembly line in the Fujian Three Gorges Offshore Wind Power International Industrial Park. The turbine is currently the wind turbine with the largest impeller diameter of 252 meters, the highest wind energy conversion efficiency of a unit of the same capacity, and the largest single-unit capacity in the Asia-Pacific region. It is worth mentioning that Shenzhen Inovance Technology Co., Ltd. (“Inovance Technology”) provided the unit with the PD802 Plus-80A high-power pitch driver and MD810 yaw frequency converter, helping the wind turbine with the largest impeller diameter in the world succeed. Offline, while escorting the stable operation of wind turbines throughout their life cycle.

Under the “Double Carbon” goal, offshore wind power, as a potential clean energy, has the advantages of large resource potential, good wind energy conditions, few limiting factors, and close distance to loads. Utilization will play an important role. In recent years, with the innovation of offshore wind power technology and the drive of grid parity, the development of my country’s offshore wind power has shown a trend of “deep sea” and “large-scale”. Large-scale wind turbines have also become one of the effective ways for wind farms to reduce the cost of electricity. one.

The advent of the 13.6MW unit marks that China’s offshore wind power large-capacity unit R&D and manufacturing capabilities have entered the world’s advanced ranks, pushing the power generation performance and reliability of my country’s offshore wind power products to a new level.

In order to meet the “large-scale” and “deep-sea” needs of offshore wind turbines, Inovance released the PD802 Plus 80A high-power pitch driver as early as October last year, filling the product gap of domestic brands in high-power drives.

Inovance Technology PD802 Plus High Power Pitch Driver

PD802 Plus has a rated output current of 80A and an overload current of 300A/3S. The high overload capacity meets the extreme load application scenarios under strong wind conditions, and the C5M anti-corrosion level design meets offshore application scenarios. The PD802 Plus pitch driver is equipped with a standard bus communication interface, which is suitable for dual-drive solutions and can meet the application requirements of 6MW to 20MW units. This drive not only breaks through the pitch drive technology of 15MW+ large-scale offshore wind turbines, but also becomes the first product in China that meets both drive PLd and system PLe safety certifications, which can help customers reduce costs and increase efficiency.

Inovance Technology MD810 Yaw Inverter

In addition, the Inovance MD810 yaw inverter adopts a common bus architecture, which can effectively improve power efficiency and achieve 5% to 30% energy saving. The product is modular in design, smaller in size, and easier to install and maintain. The MD810 intelligent frequency conversion yaw solution has the functions of backlash compensation and redundant control, which can improve the reliability and typhoon resistance of offshore wind turbines.

In the future, Inovance Technology will continue to contribute wisdom to the development of offshore wind power to the deep sea, reduce costs and increase efficiency, adhere to innovation-driven, and practice the “double carbon” goal.
