随着中国风力发电的迅速发展，风电机组的发电量和可靠性备受运营商的重视。文中就大水坑风电场MWT/2．5 MW风机和MWT/1 MW风机2种不同结构的风电机组的发电量进行了对比分析，阐明了变速恒频风电机组对比变桨恒速方式的风电机组，在低风速下具有追踪最大风能的技术优势，大幅提高了风机的发电效率。
隨著中國風力髮電的迅速髮展，風電機組的髮電量和可靠性備受運營商的重視。文中就大水坑風電場MWT/2．5 MW風機和MWT/1 MW風機2種不同結構的風電機組的髮電量進行瞭對比分析，闡明瞭變速恆頻風電機組對比變槳恆速方式的風電機組，在低風速下具有追蹤最大風能的技術優勢，大幅提高瞭風機的髮電效率。

With rapid development of wind energy in China, electricity generation and liability of WTGs extremely draw more attention of the farm operators.In this paper, electricity generation by two different WTGs of MWT/2.5 MW and MWT/1 MW are compared and analyzed, describing that, compared with WTGs with variable pitch constant speed, WTGs with variable speed constant frequency is with the technical advantage of tracking the maximum wind energy at lower speed.This largely improves efficiency of electricity generation of WTGs.
