Influence of Wind-Thermal Installed Capacity Ratio to Wind-Thermal Bundled System Transient Stability
The transient stability mechanism of wind turbines based on doubly-fed wind turbines and synchronous motors is analyzed theoretically.Then the dynamic model of wind turbines based on doubly-fed wind turbines and synchronous motors is used to simulate the impacts of different wind-thermal installed ratios on the grid transient stability.The digital simulations verify the theoretical analysis.It is concluded that in the wind-thermal bundled transmission system,the influence of double-fed wind turbine on the system transient stability depends on the effects of the doubly-fed wind turbine on synchronous motor electromagnetic power in the event of power system failure,and that the influence of wind-thermal installed capacity ratio on the system transient stability depends on the first swing instability in the event of the system failures.
