风力发电是通过风力发电机将风能转换为电能，并将产生的电能通过适当的变换和控制，传输到公共电网，其中机械能转电能、电能调节与变换、并网控制等过程，是确保风力发电系统稳定、高效、安全地向电网输送电能的关键。风力发电并网的核心功能包括电能输出稳定性、功率控制、电网保护、电能质量管理和并网协调。随着技术的进步、政策的支持和对可持续能源的需求增加，风力发电在全球范围内得到了广泛的应用，并在实现能源多样化和减少对化石燃料依赖方面发挥越来越重要的作用。

Wind power generation is the process of converting wind energy into electrical energy through wind turbines, and transmitting the generated electrical energy to the public grid through appropriate transformation and control. The processes of converting mechanical energy into electrical energy, regulating and transforming electrical energy, and grid connection control are key to ensuring the stable, efficient, and safe transmission of electrical energy from the wind power generation system to the grid. The core functions of wind power grid connection include power output stability, power control, grid protection, power quality management, and grid coordination. With the advancement of technology, policy support, and increasing demand for sustainable energy, wind power has been widely applied globally and plays an increasingly important role in achieving energy diversification and reducing dependence on fossil fuels.
