利用软起动器对风力发电机组并网过程中感应发电机的运行行为进行了仿真。当风力涡轮机单独运行时，在弱系统中为本地负荷供电时，有关风力涡轮机与电网连接的问题显得更加明显。无功功率对电压的导数有很大的依赖性，这使得稳态等效电路不适合研究电压降。描述了软起动器的模型和可行的接线策略，并进行了仿真，说明必须考虑感应发电机的动态模型。
The simulation of the behavior of an induction generator during the connection of a wind turbine by means of a soft starter is presented. The problems concerning the connection of a wind turbine to the network appear more evident when the wind turbine operates alone feeding local loads in weak systems. The reactive power depends significantly on the derivative of the voltage which made the steady state equivalent circuit unsuitable for the study of the voltage drops. A model of the soft-starter and a feasible connection strategy is described and the simulations performed, illustrating that a dynamic model of the induction generator must be taken into account.
