基于功率传输平衡视角的双馈风电机组暂态同步稳定性分析与增强

During low voltage ride through, the DFIG-based wind turbine faces the risk of transient synchronization instability, due to the absence of equilibrium point. To cope with it, this letter analyzes the existence mechanism of equilibrium point from the perspective of active power transmission balance. Then, a power transmission balance control is proposed to enhance synchronization stability, which ...
