摘要
提出一种改进型的磁链观测方法,利用全阶段定子磁链观测器进行定子磁链观测。为了验证提出理论的可行性,在1.5 MW双馈风机并网试验平台进行了风电机组并网、空载离网等试验。试验数据显示,全阶段观测器不仅能够满足正常运行观测,而且在电网电压跌落等极端工况下观测准确性也能满足并网控制要求。
This paper proposed an improved stator flux observation method which uses full phase stator fluxobserver to carry out stator flux observation. In order to verify the feasibility of the method, in 1.5 MW doubly-fedfan exparimental platform,the paper simulated the grid-connected, no-load and off-grid of the fan experiment. Theexperimental results show that the full phase observer in doubly-fed wind power generator can not only meet therequirement of normal operation observation, but also have good accuracy under different load, even under extremeconditions such as grid voltage drop,which satisfies the requirement of grid-connected control.
