Abstract

In this paper, the impedance models of two doubly fed induction generators（DFIGs） are established. Based on the RLC impedance stability criterion, the SSO characteristics of grid-connected system under different wind speed and control parameter for each DFIG were investigated, and the conclusion was verified by simulation. The final results show that there is a difference between DFIGS at different locations under different control parameters and wind speeds, and the difference will change when control parameters and wind speed changes.

Key words

wind farms / subsynchronous resonance / asynchronous generators / doubly fed induction generator（DFIG） / multiple wind turbines / impedance model
