Abstract

Aiming at the phenomenon of subsynchronous oscillation (SSO) caused by direct drive wind turbines under weak power grid, a dual-channel additional damping strategy based on subsynchronous current is proposed for suppression. Firstly, the influence of weak power grid on SSO is verified, and secondly, combined with the direct drive fan connected to the weak power grid to extract subsynchronous current from the system to analyze the suppression mechanism, the structure of additional damping controller and its parameters are designed. Then, an impedance model considering the frequency coupling additional damping control link is established and its stability is verified. Finally, the proposed strategy is simulated and compared with undamped control and traditional single-channel damped control. The results show that compared with undamping control and single-channel damping control, the proposed method reduces the SSO fluctuation range, suppresses SSO phenomenon more effectively and has better adaptability.
