In recent years, the annual growth rate of the utilization of global renewable energy sources reaches 25%, the utilization of the renewable energy sources is dominated by the power industry, and the power generation proportion of non-hydraulic renewable energy sources is expanded by two times. It is statistical that renewable energy is consumed about 14 hundred million (wt.) oil equivalent in 2002, and will exceed 22 hundred million (wt.) oil equivalent in 2030. Wind power generation is the most mature renewable energy power generation except hydroelectric power generation, and the installed capacity of the wind power generation accounts for the vast majority of the total installed capacity of the whole renewable energy power generation. However, due to the limitation of the performance of the power electronic device, a certain bottleneck is caused to the development and application of a large-capacity wind turbine generator. With the further development of power electronic devices and energy storage devices of large power strings, wind power generation can compete with conventional energy in terms of total investment or power generation cost, and the wind power generation technology can be developed more greatly. In addition, with the continuous increase of the capacity of the wind power plant, when the voltage of the power grid drops, it is more important to ensure that the wind turbine generator does not operate in a grid-disconnected mode and maintain the stability of the regional power grid. With the development of high-power electronic devices and control technologies thereof, the low-voltage ride through problem of the existing wind turbine generator can be well solved. The wind generating set can be divided into a double-fed wind generating set with a multi-stage speed-increasing gear box, a direct-drive wind generating set without the speed-increasing gear box and a semi-direct-drive wind generating set with a one-stage speed-increasing gear box according to the structural form of a main transmission chain, and can be divided into a constant-speed constant-leading wind generating set and a variable-speed constant-frequency wind generating set according to the rotating speed adjusting mode of the wind generating set.
