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.
