The converter of the double fed asynchronous wind

  • Detail

Recently, Beijing Lide Huafu company officially announced that the 1.5MW doubly fed asynchronous wind turbine converter, a cooperation project between Beijing qingneng Huafu Wind Power Technology Co., Ltd. and Tsinghua University, which was invested and established by Beijing Lide Huafu company, was successfully developed, and passed the ground full load test of Lanzhou electric machinery plant at one time. Lide Huafu is a leading enterprise in the field of high-voltage inverter in China. Since the first high-voltage inverter prototype came out, it has been engaged in the research, development, production and sales of energy-saving, environmental protection and renewable energy products. This cooperation with Tsinghua University to jointly enter the wind power market is based on the deep research and development foundation, advanced production technology and mature application experience in the power industry of Lide Huafu, combined with the advantages of Tsinghua University in the field of technology and talents, to find the verticality of the oil cylinder, and the outstanding results obtained through the long-term unremitting efforts of both sides. Both sides hope to break the monopoly of foreign enterprises in this field, so as to drive the overall development of national industry

in recent years, wind power generation has shown a strong development momentum in the whole world power market. In order to promote the development of parallel wind power generation, the medium and long term development plan of renewable energy formulated by the national development and Reform Commission clearly requires that the national installed capacity of wind power will reach 5million kW in 2010 and 30million kW in 2020. The national development and Reform Commission and the Ministry of science and technology have included "megawatt wind turbines" in the national major industrial development plan during the Tenth Five Year Plan period. The issuance and implementation of China's first renewable energy law on January 1st, 2006 has created a good legal and planning framework for the development of renewable energy in China. Statistics show that by the end of 2005, 61 wind farms have been built in China, with a total installed capacity of 1.266 million KW and 1864 wind turbines installed. On the other hand, domestic products accounted for only 22.7% of the cumulative market share in 2005, and the wind power market for units above MW level was mainly monopolized by foreign products

the backwardness in technology and equipment manufacturing is the key problem that restricts the development of China's wind power industry. The converter of doubly fed asynchronous wind turbine is the core component of variable speed constant frequency doubly fed asynchronous wind turbine. China has not been able to develop mature industrial products, which mainly depends on imports. The "qhvert-dfig1500b" doubly fed asynchronous wind turbine converter launched by Beijing qingneng Huafu Wind Power Technology Co., Ltd. is a doubly fed asynchronous wind power generation technology based on AC DC AC bidirectional converter, which adopts full digital vector control method and belongs to the international cutting-edge technology. This technology can optimize the operation of the wind power generation system, realize variable-speed constant frequency power generation in a wide range of wind speeds, improve the efficiency of the fan and the working condition of the transmission chain, reduce the loss of the generator, improve the operation efficiency, and improve the utilization rate of wind energy. It has a broad development space to restore the experimental machine to its original state

1.5mw doubly fed asynchronous wind turbine converter all core technologies, qingneng Huafu has completely independent power coal price doubled from the lowest price at the end of last year. With the successful listing of this product, it will break the monopoly of foreign products in this field at one fell swoop, reduce the cost of wind power equipment in China, and also mark the rise of national industries in the field of wind power
