双馈风力发电系统故障穿越性能改善的控制策略
Control strategy of fault ride-through performance improvement for double-fed wind turbine generation system
摘要
Abstract
The conventional control strategy (e.g.,PI control) limited the fault ride-through capability of doubly-fed wind turbine generation system.So a fault ride-through strategy-based multi-switch control is proposed.Using the fast transient performance of multilevel hysteresis current vector controller,the overcurrent of rotor windings is suppressed during the transient period of terminal voltage dip.Meanwhile,a set of dynamic resistors in series with the rotor windings are implemented,which further restrains the overvoltage and overcurrent of the rotor windings.The implementation processes of the multilevel hysteresis current vector controller and the fault ride-through strategy-based multi-switch control are introduced in detail.Aiming at three typical terminal voltage dip types of DFIG,the dynamic simulation model of the proposed fault ride-through control strategy is built on Matlab/Simulink platform,and its feasibility is validated.The simulation results show that the proposed fault ride-through control strategy improves the fault ride-through performance of doubly-fed wind turbine generation system.关键词
