Chongqing Daily reported on November 18 that the Chongqing Municipal Science and Technology Commission reported on November 17 that the first 2MW variable-speed constant-frequency wind turbine with independent intellectual property rights in China was successfully developed in Chongqing. This is currently the largest power wind turbine in China, with an annual capacity of 2,000 kWh.
This wind turbine prototype was jointly designed by CSIC (Chongqing) Haizhuang Wind Power Equipment Co., Ltd. and Germany aerodyn. The company realized its independent development through digestion and absorption, and it will be transported to Huitengxile in Inner Mongolia this month. The wind farm was installed and trialed and officially merged into the national grid.
The use of wind power to generate electricity is a major measure in China's clean energy industry, but wind power equipment has always been the biggest problem affecting industrial development. Before 2006, China could only use wind turbines with constant speed and constant frequency and low power to carry out wind power generation. “The constant speed constant frequency cannot fully utilize wind energy.†The relevant professionals explained that the wind is in different geographical environments. And the climatic conditions, the speed is not the same, if the wind power equipment we use always collect them at a speed and a frequency, in addition to not getting more wind energy, it will also affect the efficiency of power generation. So in 2006, Dalian Heavy Industry Group and Dongfang Steam Turbine Co., Ltd. began to develop the variable speed constant frequency wind turbines and completed the small batch production of the prototype.
"In spite of this, the maximum power of the unit equipment is only 1.5MW, and it also adopts the key technology monopolized by Germany, Spain and other countries, greatly increasing our 'load' for equipment R&D and use." A person in charge of Haizhuang said that currently The market price of wind power equipment per kilowatt is about 6,000 yuan, and its use cost is extremely expensive.
As an early intervention of the wind power industry, the project of “Key Technology Development and Industrialization of High-Power Wind Turbinesâ€, which was led by Haizhuang Company, started at the end of 2006, and it is in the “Eleventh Five-Year†major science and technology project in Chongqing and the new industrialization project of the city. With the support of capital projects, it has overcome the system integration technology of a group of high-power wind turbines such as unit drive chain and cabin optimization layout, and has the design and manufacturing capabilities of “full power test, system integration and re-engineeringâ€. Invested hundreds of millions of dollars.
Chongqing successfully developed 2MW variable speed constant frequency wind turbine
Chongqing enterprises have successfully developed the first 2MW variable-speed constant-frequency wind turbine with independent intellectual property rights in China, which is currently the largest power wind turbine in China, with an annual generating capacity of 2,000 kWh.
