摘要
风电机组低电压穿越(LVRT)能力的深度对机组造价影响很大,根据实际系统对风电机组进行合理的LVRT能力设计十分必要。文章分析了定速异步风机、同步直驱式风机和双馈风机三种重要机型在电网电压跌落时的暂态特性,并叙述了简要的LVRT方案。
The depth of the capacity of LVRT poses great impact on the cost of the generating set, so it is of great necessity to make reasonable design of LVRT capacity to the wind generating set according to the actual system. The article analyses the transient state of three important types of constant speed induction fan, synchronizing upright fan and doubly fed fan, and state the the LVRT scheme.
