Research on control method of doubly-fed asynchronous wind turbine under complex operating conditions

In the context of the global energy structure transformation, wind energy, as a renewable energy source, plays a crucial role in reducing greenhouse gas emissions and promoting sustainable development. In order to meet the high standard requirements of frequency and voltage stability, the operation control technology of generators is facing unprecedented challenges. As one of the current mainstream asynchronous generators, double-fed asynchronous wind turbine, its frequency converter, as the core control technology, shows the remarkable potential of optimizing energy conversion under the condition of wind speed change. In this paper, the working mode of double-fed asynchronous wind turbine and the core functions of frequency converter in the system are analyzed, and the specific technical strategy of double-fed asynchronous wind turbine operation control is discussed in detail from two dimensions of technical application and algorithm optimization. The aim is to comprehensively improve the operation and control efficiency of doubly-fed asynchronous wind turbines, so as to improve the comprehensive performance of the whole wind power generation system, reduce the dependence on traditional energy, and promote the realization of more lasting and sustainable energy utilization.
