【摘要】：大量基于电力电子设备的非同步电源和无功补偿装置接入形成了新型电力系统,使得集群风电与电网之间以及与邻近电力电子驱动设备之间的交互作用十分复杂,电力系统的故障运行特性可能发生改变,从而给电网的安全稳定运行带来多方面的挑战。通过对系统扰动在双馈风电机组和静止无功发生器内传导过程的理论分析,分别给出了其动态响应特性,推导了双馈风电机组与静止无功发生器在系统扰动下相互激励的表现形式,分析了双馈风电机组与静止无功发生器之间交互作用对双馈风电机组转子侧变流器控制参数和静止无功发生器控制参数的敏感性,并给出双馈风电并网系统的振荡特性。最后,通过时域仿真验证了上述理论分析的正确性。
[Abstract]:A large number of non synchronous power and reactive power compensation devices based on power and electronic equipment are connected to form a new type of power system, which makes the interaction between the cluster wind power and the power grid and the adjacent power electronic driving equipment very complicated. The fault operation characteristics of the power system may be changed to the safe and stable operation of the power grid. The dynamic response characteristics of the system disturbance in the double fed wind turbine and the static var generator are analyzed. The performance of the double fed wind turbine and the static var generator under the system disturbance is derived, and the doubly fed wind turbine and static reactive power are analyzed. The interaction between the generators is sensitive to the control parameters of the rotor side converter and the control parameters of the static var generator, and the oscillation characteristics of the doubly fed wind power grid system are given. Finally, the correctness of the theoretical analysis is verified by the time domain simulation.
