Abstract :
In order to analyze the small signal stability of the grid interconnection of different types of wind turbines, in the PSAT simulation environment, this paper establishes simulation model with IEEE3 machine 9-bus system as a prototype, and the small signal stability of power system connected with 3 kinds of wind farms is respectively simulated and compared. The results show that, due to the isolation effect of converter, different connections of generator and grid have a greater impact on the small signal stability of the system; the converter will reduce the small signal stability of the system.
