Abstract

Aiming at the sub-synchronous oscillation（SSO） problem of direct-drive wind turbine cluster grid-connection under low operating conditions, based on the idea of graphical block modelling, the wind turbine generation （WTG）, collector line and power grid are regarded as discrete components. On the basis of establishing detailed models of each component, the linearized model of direct-drive PMSG wind farm under different collector circuit topological structure is constructed. The oscillation modes in the system are identified by using the eigenvalue analysis method and impedance analysis, then the influence of current inner loop control parameters, operating conditions and WTGs number on the frequency and damping is analyzed. The results show that the oscillation phenomenon is caused by improper setting of d-axis current inner loop control parameters. Finally, a time-domain simulation model of direct drive PMSG based on wind farm connected to AC network is built in EMTDC/PSCAD and the simulation results verify the accuracy and validation of the theoretical analysis.
