| Abstract: | Based on the mathematical model of the direct-drive permanent magnet wind turbine, the analysis model about small signal stability of simple wind power system was inferred. This paper analyzed the small signal stability, system oscillation mode and system damping characteristics of simple wind power system. Finally, the simulation model was built in the Matlab/Simulink. The eigenvalue analysis method was verified through this simulation. The analysis indicated the direct-drive permanent magnet wind turbine of this pa- per was small-signal stability. |
