In recent years, the subsynchronous oscillation (SSO), which occurs in direct‐drive permanent magnetic synchronous generators (D‐PMSGs)‐based wind farm, has great impact on stability of power system. The different parameters and operation conditions D‐PMSGs lead to interaction (SSI) among D‐PMSGs. What is more, SSI will influence SSO characteristics system D‐PMSGs‐based farm integrated AC network. Here, considering difference or eigenvalue analysis, based small‐signal state‐space model two aggregated are equivalent carried out. Then between can be studied, dominant D‐PMSG determined participation factors. Lastly, detailed electromagnetic transient simulation built PSCAD/EMTDC. conducted corroborate analysis. result shows that an obvious exists Furthermore, indicate study problem may leave out some useful information.
