China's doubly-fed asynchronous wind turbine converter successfully developed

Recently, the cooperation project of Beijing Qingneng Huafu Wind Power Technology Co., Ltd. and Tsinghua University, which was established by Beijing Lidehuafu Co., Ltd., successfully developed a 1.5MW doubly-fed asynchronous wind turbine converter and passed the Lanzhou Motor Factory. Ground full load test. Leadworth is a leading company in the field of high-voltage inverters in China. It has been engaged in research, development, production and sales of energy-saving, environmentally-friendly and renewable energy products. This time, cooperation with Tsinghua University to enter the wind power market is based on Li De Huafu's deep research and development, advanced production technology and mature application experience in the power industry, combined with the advantages of Tsinghua University's technology and talents, through the long-term unremitting efforts of both parties. Outstanding results.

In recent years, wind power has shown a strong momentum in the entire world power market. In order to promote the development of grid-connected wind power generation, the “Renewable Energy Medium- and Long-Term Development Plan” formulated by the National Development and Reform Commission clearly requires that the national wind power installed capacity will reach 5 million kilowatts in 2010 and the national wind power installed capacity will reach 30 million kilowatts in 2020. During the 10th Five-Year Plan period, the National Development and Reform Commission and the Ministry of Science and Technology have included the “MW-class wind turbines” in the national major industrial development plan, and the implementation of the first “Renewable Energy Law” in China on January 1, 2006 It has created a good legal and planning framework for the development of renewable energy in China.

At present, the backwardness of technology and equipment manufacturing is a key issue that restricts the development of China's wind power industry. The doubly-fed asynchronous wind turbine converter is the core component of the variable-speed constant-frequency doubly-fed asynchronous wind turbine. It has not been able to develop mature products in China, mainly relying on it. import. The "QHVERT-DFIG1500B" type doubly-fed asynchronous wind turbine converter introduced by Beijing Qingneng Huafu Wind Power Technology Co., Ltd. adopts the all-digital vector control method and belongs to the international leading edge technology. The technology can optimize the operation of the wind power generation system, realize variable speed constant frequency power generation in a wide wind speed range, improve the fan efficiency and the working condition of the transmission chain, reduce the generator loss, improve the operation efficiency, and improve the wind energy utilization rate.

Qingneng Huafu owns the complete independent intellectual property rights of the product. With the successful listing of products, it will break the monopoly of foreign products in this field and reduce the cost of wind power equipment in China. It also marks the rise of national industries in the wind power sector.
