Hitachi ABB Power Grids launches its first high-voltage hybrid switchgear for offshore wind power generation
Hitachi ABB Power Grids recently launched its first new 72.5 kV high-voltage hybrid switchgear for offshore wind power – the semi-enclosed combination electrical appliance wind turbine version (PASS M00 WT). This allows for power collection lines between wind turbines to operate at a higher voltage level, helping to meet the world's growing demand for renewable energy.
This innovative solution is about to provide technical support for China's first 66 kV offshore wind farm. In the Zhejiang Huadian Yuhuan Phase I 300 MW offshore wind power project, Hitachi ABB Power Grids will provide 72.5 kV semi-enclosed combination electrical appliances to Dongfang Electric Wind Power Co., Ltd., the wind turbine supplier for the project, helping to optimize the energy structure of the Yangtze River Delta region.
China is driving the process of its "energy revolution" through cleaner, more efficient, and more digital technologies. According to the International Energy Agency's forecast, by 2024, China's renewable energy generation will account for 40% of the global total.
The Huadian Yuhuan Phase I offshore wind power project will be completed at the end of 2021. It is expected to have an annual equivalent full-load operating hours of 2593 hours, providing electricity for approximately 240,000 households in Zhejiang Province. It will also reduce carbon dioxide emissions by 584,000 tons, equivalent to the annual carbon emissions of over 12,600 small passenger cars.
The semi-enclosed combination electrical appliance (PASS M00 WT) is a compact high-voltage hybrid switchgear designed specifically for wind turbine applications. Easy to install inside the wind turbine tower, it can withstand vibrations and sudden movements in harsh environments, providing maximum safety assurance for wind farm operators. The new switchgear is equipped with a digital electric mechanism, and a control cabinet with built-in intelligent monitoring and diagnostic functions. Its relay protection system can be seamlessly integrated into the substation automation system via the IEC61850 interface. The switchgear also uses real-time simulation to achieve proactive management and remote service of the equipment's lifecycle.
Markus Heimbach, Global Head of High Voltage Products Business Unit at Hitachi ABB Power Grids, said: "Our new technology will provide strong support for renewable energy grid connection and help reduce carbon footprints. Hitachi ABB Power Grids is committed to shaping the future of sustainable energy and driving energy transformation by building stronger, smarter, and greener grids."
