On October 17, 2018, Goldwind released 4 newly-developed smart wind turbines at the Innovation Theater of China Wind Power 2018: large capacity offshore GW168-8MW, large rotor offshore GW184-6.45MW, typhoon-adaptive and low-wind-speed offshore GW168-6.45MW, and low- and medium-wind-speeds onshore GW155-3.3MW, creating more value for customers with more LCOE-competitive products and solutions.

Wu Gang, Chairman of Goldwind, said: "Goldwind aims to create value for customers, and works relentlessly to make technical innovation based on the needs of the market and customers. As wind power accelerates towards grid parity, Goldwind will continue to give full play to its advantage in overall supply chain. We are committed to providing fast, accurate, environmentally friendly and integrate solutions for customers with optimal LCOE, leading the technical progress in the industry and improving the competitiveness of wind power."

Ten years of independent development leads to offshore breakthrough

Goldwind has been actively exploring the offshore market and developing the offshore wind power technology for many years. It has made a great amount of R&D investments and reserves in equipment reliability design, installation, operation and maintenance (O&M), etc.

After the launch of GW3S and GW6S offshore platforms and with years of accumulation, Goldwind has independently developed the GW168-8MW offshore smart wind turbine, applicable to wind class IEC I. It is currently the largest offshore wind turbine in terms of capacity in China. By reducing the number of turbines and construction area, the requisition fees and costs of foundation, construction, installation and cable laying can be effectively reduced. With a rotor diameter of 168 m, it has stronger power generation capability and better economic performance.

The GW168-8MW model has used many innovative technologies, reliability design plan, and is equipped with integrate transportation and installation plan, iGO smart O&M system and other service platforms independently developed by Goldwind, its LCOE is optimized through the project lifecycle in an all-round way. For example, the innovative E-top nacelle integrate design places all electrical equipment in the nacelle, which can greatly reduce cable costs and save onsite commissioning time. It adopts integrate and smart water-cooling system design, E-plus low temperature design, typhoon adaptation design, etc. This model has obtained the design certificate from authoritative certification body, and it is expected to complete the installation of first prototype in the second half of next year.

In addition to the breakthroughs in 8MW model, Goldwind also released the large rotor offshore GW184-6.45MW, typhoon-adaptive and low-wind-speed offshore GW168-6.45MW, further expanding the coverage of GW6S offshore platform in segment market.

The GW184-6.45MW model has set a new record with the largest rotor diameter in the world. With the guarantee of reliability and safety, it adopts customized load shedding strategy and technical solution to significantly improve power generation. For example, its annual equivalent hours can be up to 3,386 hours at the average wind speed of 7.5 m/s (calculated by a reduction coefficient of 0.78). This model has obtained the design certificate from authoritative certification body.

Further expansion in low- and medium-wind-speeds onshore market

At this conference, Goldwind launched a new member, the GW155-3.3MW model, into the large megawatt onshore 3S platform for the global market. Designed for low- and medium-wind speeds market, this model can be customized and configured with different types and specifications of towers, effectively supporting the GW3S platform to cover all wind classes and provide higher power generation performance and adaptability solutions for the development of low wind speed resources.

The GW155-3.3MW model has followed the mature electric drive chain dual-line technology of the 3S platform and made optimization and upgrade in load shedding and noise reduction. With POWERNESTTM wind farm control system, EFarm LiDAR smart control technology and other digital solutions, its environmental friendliness and overall power generation have been enhanced. For example, the annual equivalent hours can reach more than 2,000 hours at an average wind speed of 5 m/s (calculated by a reduction coefficient of 0.78). The installation of the first prototype is in progress.
