Abstract

Static var compensator (SVC) and thyristor controlled series compensator (TCSC) are used to improve Transient Voltage Stability of the asynchronous wind farm in this paper. The related structure model of the wind farm power system is built in Matlab / Simulink. The contributions of SVC and TCSC to Transient Voltage Stability of the asynchronous wind farm and power grid are verified by the simulation. The result shows that: when the wind speed is in random fluctuation, SVC can offer reactive power to maintain the transient stability, in addition, when three-phase short circuit happens in the wind farm integrated place of power grid, TCSC can promote the terminal voltage, and improve the low voltage ride-through capability effectively.
