Abstract

In order to reveal the mechanism of voltage stability in wind power system and influence to its voltage stability with parameters changing, for limitations of present study about wind power system voltage stability based on bifurcation theory, two-parameter bifurcation analysis were detailed. With the help of ideas that conventional electric power system to calculate the two-dimensional parameter bifurcation boundary, the node voltage two-dimensional saddle-node bifurcation boundary of wind power system was calculated by using inject active power of wind farm, SVC parameters B_max and K_r as bifurcation control parameters. And on the basis of this in-depth analysis, the laws that parameters affecting the wind power system voltage stability were obtained.
