| 摘 要： | 为研究电网扰动下双馈风力发电机(DFIG)暂态行为和抵御电网扰动的技术措施.针对单机无穷大系统,定义了DFIG功角并分析其暂态行为.由于DFIG的功角与转子位置无关,其暂态行为是电磁暂态过程,故具有快变特点.在电网故障扰动下,DFIG的功角可能大幅变化,通过相量图分析发现功角大幅变化是导致机端电压严重跌落和转子过载的主...

| Abstract: | For studying the transient performance of DFIG(Doubly Fed Induction Generator) of under grid disturbance and developing the technical countermeasures,the power angle of DFIG is defined and its dynamic behavior is analyzed for a single-machine infinite system.As the power angle is independent of the rotor position and its transient behavior is an electromagnetic process,it varies quickly and greatly during grid disturbances.The analysis of vector chart demonstrates that the great variation of power angle cau... |
