摘要

With the increasing capacity of wind power grid, the influence of wind power on system transient stability cannot be ignored; the wind power access location has an important influence on the dynamic behavior of synchronous machine after disturbance. For the study of wind power access location influence mechanism on the transient stability of power system, this paper uses the extended equal area criterion to analyze the impact of wind power access on the electromagnetic power fluctuations of critical units and the remaining units, and obtains the impact of wind power access location on the transient stability of the system. The analysis results show that, when the synchronous machine near the disturbance of wind turbine is critical unit, wind power will deteriorate the system transient stability; when the synchronous machine near the disturbance of wind turbine is remaining unit, wind power is beneficial to transient stability.
