| Abstract: | To solve the voltage stability problem of the grid-connected wind farm,various calculation methods for the capacity of the reactive compensation capacitor as well as its switching modes are proposed based on the var-voltage characteristics of the wind turbine generator.According to the reactive power demand features of the wind power,the working principle and characteristics of the TCR with FC(SVC) are identified and analyzed.The reactive compensation results of a wind farm by using SVC show that the SVC can provide dynamic voltage support,stabilize the node voltage of the wind farm,and reduce the impact of wind power fluctuation on the grid voltage. |
| Keywords: | power system wind power generation voltage stability reactive compensation SVC |
