Improvement of Transient Voltage Stability of the Wind Farm Using SVC

Abstract:

Static var compensator (SVC) is used to improve transient voltage stability of the asynchronous wind farm. The issue of voltage stability and transient stability of wind power system are also addressed. A novel control strategy of SVC is proposed instead of the types of traditional feedforward and uniline feedback to control SVC. The proposed method makes control performance better and the compensation efficiency higher. At the same time, balanced compensation strategy of orientation vector conversion is applied instead of traditional model of steady-state phasor to calculate the compensation electrical susceptance. Using this method can overcome the shortcoming of dynamic characteristics and adaptability. At last, the simulation results indicate this control strategy could improve the stability of wind farm effectively and quickly.
