To the grid connected wind turbine, the purpose of controlling it working at optimal tip speed ratio or about is to capture maximum wind energy.

对并网型风力机，控制其在额定风速下运行在最佳叶尖速比或其附近，主要是希望它能捕获到最大的风能。

The speed reference for the controller is a function of the wind speed and is chosen to ensure maximum energy capture from the wind for varying wind conditions.

控制器的参考转速是风速的函数，它的选择随风力状况的变化而变化，目的是为了获取最大风能。
