摘要
风能最大的特点就是不稳定性与随机性,利用微网可以弥补风力发电天然的缺陷。通过合理设定高频交流的运行频率,可有效的减小风力发电机的滤波器体积、变压器体积,高频电相比于工频也更易于滤除谐波,使得风力发电的质量得到改善。在实际含风能高频交流微网的设计中,输电线路损耗和风力发电机结构是限制运行频率的两个重要因素,文章基于此二者详细探讨了如何合理选择含风能高频交流微网的运行频率。
The obvious ligatures of wind power are instability and randomness,but this two weaknesses can be remedied by micogrid. By setting a reasonable operating fi＇equency ofhigh-fi＇equeney AC micogrid,the sizes of filters and transformers in the wind turbines can be reduced.What is more,the harmonics of high fi＇equeney compared to the harmonics of power frequency is more easily filtered,it improves the quality of wind power.In the design of high frequency AC microgrid,two factors that is transmission loss and turbine structure limit the operating fi＇equency.Some reasonable operating frequency ranges are chosen on the base of full consideration of transmission losses and different wind turbines.
