Dn80止回阀时对国内现阶段风力人才极为担忧。

相关资料显示，2020年我国将会有几十万人从事风力发电产业，其中需要专业人员几万人，然而目前我国尚没有专门的风电人才培养基地。

华北电力大学校长刘吉臻认为，未来风电毕业生要具有进行风力发电机组和风电场的设计、制造、运行、试验研究以及项目投资与管理的基本能力，需要有一定创新能力、较强实践能力和良好发展潜力的高级专门人才。

据悉，华北电力大学新增了国内惟一的风能与动力工程本科专业。

华北电力大学还首批招收了30名风电专业本科新生，刘吉臻向中国经济时报表示，“4年之后，中国的风电市场将急需风力发电人才，而风电人才的培养要走高起点、高层次的道路，而不能只是培养一般的技术员。
