摘要
通过建立Matlab双馈机组风力发电仿真系统、增加频率控制环节,模拟系统频率变化时双馈风力发电机短时释放或吸收转子动能的情况,研究其辅助系统频率控制的作用。仿真结果显示,含双馈风力发电机组的风电场也能像常规机组一样参与系统辅助频率控制。
This paper establishes the simulation system of DFIG based on matlab which increases the frequency control loop.When the system frequency alters,releasing or absorpting part of the rotor kinetic energy in shortterm to realize the function of participating in ancillary frequency control system.The simulation results shows that wind farm with doubly-fed wind turbine also can participate in ancillary frequency control as the conventional unit.
