大规模风电接入对系统功角稳定性影响的研究
Research on the effect of large-scale wind power integration on the power angle stability
According to large-scale wind power access to the sending end system, a transient power angle stability analysis method considering wind power is proposed theoretically in this paper. The impedance model is used to simplify the fan, mixing the active and reactive power information of wind power into the admittance matrix of the system. Through further quantitative analysis of the rotor motion of synchronous machines (SMs) after wind power integration, it can be seen that wind power integration has impact on both mechanical power and electromagnetic power of SMs under replacement conditions. Finally, through theoretical calculation and simulation verification of multi-machine small-scale system, it is concluded that in the process of increasing the proportion of wind power at the supply end, the change of transient acceleration area is the dominant impact factor of power angle stability in the early stage, while deceleration area in the later stage.
