Recently, Dongfang Electric Wind Power Co., Ltd. won the bid for the Three Gorges Group Fujian Xinghua Bay Phase II (Bid Section II) offshore wind power project and successfully obtained the first batch of offshore wind power bulk orders, which has taken a solid step in winning the battle to reinvigorate the wind power industry.
The installed capacity of the offshore wind power project in Fujian Xinghua Bay Phase II (Bid II) is 60 MW. It is planned to install 12 sets of DEW-G5000 anti-typhoon offshore wind turbines in Dongfang Wind Power.
Over the years, Dongfang Electric has devoted itself to the development of offshore wind turbines and is committed to providing users with high-performance, high-reliability offshore wind power products. On May 3rd, Dongfang Electric's first DEW-G5000 unit was the world's first high-power offshore test wind. Field - the pilot wind farm in Xinghua Bay, Fuqing was successfully put into operation and won the approval of the owners.
East Wind DEW-G5000 anti-typhoon offshore wind turbines have the adaptability of IEC Class I wind farms. The anti-typhoon design is more precise and scientific. The diameter of wind turbine is 140 meters, and the swept area per kilowatt is 3.079 square meters. The unit is equipped with self-developed resistance. Typhoon blade, which adopts blunt tail technology, is less sensitive to roughness, smooth in dynamic characteristics, and excellent in aerodynamic performance. The maximum wind energy utilization coefficient is ≥ 0.49, and the maximum wind energy utilization rate is ≥ 0.45, and the rated power generation rate is reached. 5.5 MW, able to match all kinds of offshore (land) 5 MW wind turbines, reaching the current market advanced level.
East Wind DEW-G5000 anti-typhoon offshore wind turbine adopts double-supported large-scale single-row tapered bearings. The gearbox adopts pure torque load and advanced flexible pin load sharing technology to form a highly reliable transmission chain structure; Structure, omnidirectional systemic heat balance design and sea salt spray resistance design guarantee the unit's adaptability and stability under high humidity and high salt spray environment; permanent magnet synchronous generator (PMSG) and full power inverter system have power generation The advantages of high efficiency, friendliness and stability; main control system, pitch control system adopts intelligent electronic control system fully independently developed and designed, advanced independent pitch control algorithm, best wind energy utilization coefficient curve tracking control technology and anti-typhoon control strategy, On the basis of maximizing the efficiency of power generation, system reliability has been improved; the frequency conversion system has pioneered the new technology of parallel operation and load management of two power generating units, which has both redundancy in design and operational efficiency; remote monitoring system is autonomous Design, the use of more mature data analysis; innovative cable twisted cable structure design, the first use of large parts self-maintenance program, with Replacing the main gear box, generators and other large components in the engine room to improve the operation and maintenance capabilities of the sea and reduce the operation and maintenance costs. The excellent design of the entire machine ensures the high reliability of the unit, high power generation efficiency, high level of intelligence and low maintenance. Cost; vast boundless Xinghua Bay, chasing the wind and dreaming Orientals, ten-year-grinding Ling Yunzhi, the wings of the sky dance east wind, Dongfang Electric people with nearly ten years of dedication and experience, into the offshore wind power club, effort to build economy, efficient , Stable offshore benchmark wind farm; in the future, Dongfang Electric will execute and serve with higher-quality and more efficient projects, create continuous value for users, continue to explore and innovate, provide users with more power, better performance and stronger reliability.
