Abstract
In order to reduce the loss of transmission line, capacitors are often compensated in series to improve the power transmission capacity of transmission line. However, the change of grid state caused by series capacitor increases the risk of sub-synchronous oscillation in wind farm. In order to solve the problem of sub-synchronous Oscillation, the impedance model of DFIG using virtual synchronous control method is established in the synchronous rotating coordinate system. A cooperative control method of voltage compensation and additional damping is proposed to suppress the sub-synchronous oscillation. Finally, the effectiveness of the compensation control method is verified by simulation analysis.
