The Influence of Reactive Current Injection Coefficient and Active Current Ramp Rate of DFIG on the Transient Power Angle Stability of Wind-Thermal Bundled System

With the continuous development of wind power generation, doubly fed induction generators (DFIGs) are gradually becoming the main power source of power systems, and have brought many new transient stability problems. Based on the transient control strategy of DFIG, this paper takes the wind-thermal bunched system as the research object, measures the transient power angle stability of the system using the power angle of synchronous generators (SGs), analyzes the mechanism of the effects of reactive current injection coefficient and active current ramp rate on the transient stability of the system, and obtains the influence rules of reactive current injection coefficient and active current ramp rate on the transient stability of the system under different preparation of wind power and different faults. This study provides valuable insights into determining and adjusting the transient control parameters for DFIGs.
