摘要
当前风力发电机组主流机型一般为双馈机组,其定子和转子同时馈送能量的特点,决定了其主回路部分的设计和器件选型较其他异步电机机组或同步电机机组更加复杂。分析了双馈风力发电机组主回路的工作原理并以1.5MW容量双馈机组为研究对象,给出了典型的主回路设计结构并分析了主回路各个部分的电路参数。以此为依据,给出了主回路上各部分器件的推荐选型方案。在实际产品制造中,采用该选型方案后,取得了预期的效果。
The main type of current wind power generation units is the double-fed unit.The stator and the rotor of this type unit can feed out energy simultaneously;and this feature determines that the design of the main circuit and the device type selection for this type unit are more complex than that of other asynchronous or synchronous machine unit.The working principle of the main circuit of double-fed wind power generation unit was analyzed,and taking a 1.5MW double-fed unit as studying object,the typical design of the main circuit structure was given,and the electric circuit parameters of various parts of the main circuit were analyzed.Based on this,the device type selection scheme of various parts of the main circuit was recommended.The scheme was adopted in practical product manufacturing,and the desired effect was obtained.
