A division of the China State Shipbuilding Corp (CSSC) has showcased components for an 18-MW model that surpassed the recently launched 16-MW turbine created by several Chinese companies, making it by far the largest and most potent wind turbine in the world.
As reported first by POWER Magazine, CSSC Haizhuang revealed the new turbine in the Dongying City industrial park in China's Shandong region.
Improvement of Turbine Capacity and Efficiency
The 260-meter-diameter rotor of the 18-MW unit, which was shown in a YouTube video uploaded on Jan. 6, will also operate a permanent magnet generator and a modularized medium-speed drive train.
"The H260-18MW turbine... will make a great contribution to the improvement of turbine capacity and efficiency, as well as reducing the LCOE [levelized cost of energy] of offshore wind farms, and has market prospects in high-speed wind and deep-sea areas," the company said in a press release statement.
The H260-18.0 turbine's parts, according to CSSC, showed that they had mastered the fundamental technologies of high-rating offshore wind turbines and essential components, helping the offshore wind power sector as a whole to achieve a new milestone.
The company adds that the massive turbine featured 128-meter SuperBlade+ blades with load-reducing pitch control.
Seven Football Fields
Seven football fields' worth of space is covered by the sweep of these blades, or around 53,000m2. The turbine's power train includes common blade model specifications, a flexible generator matching mechanism, as well as a balanced load.
Additionally, it has control technologies for changing pitch and torque and a holographic sensing system" for total load reduction.
The degree of aeroelastic instability brought on by the interaction of vibration and pressure concentrations on the blades is supported by multi-source online monitoring so that blade flutter can be reduced by 10%.
CSSC Haizhuang anticipates that the blades will eventually reduce vibrations in the turbine's tower and foundations by more than 50%.
40,000 Houses
The H260-18MW will be able to generate 44.8 kilowatt hours of power every revolution when working at full capacity. A single model may produce enough energy to supply 40,000 houses for an entire year, as per Interesting Engineering.
According to CSSC Haizhuang, the adaptive energy-increasing control technology increases each turbine's capacity to generate electricity by 3%. The company claims that each turbine would be able to generate 74,000 MWh of electricity yearly.
CSSC Haizhuang is banking on huge, high-reliability wind turbines to expand wind power use and reduce costs.
