风电接入位置对系统暂态稳定性的影响分析
摘要:随着风电并网容量逐渐增加，风电对系统暂态稳定性的影响不容忽视，风电接入位置对受扰后的同步机动态行为具有重要影响。为研究风电接入位置对电力系统暂态稳定的影响机理，采用扩展等面积法则，分析了风电接入对临界机组和余下机组电磁功率波动的影响，得出风电接入位置对系统暂态稳定性的影响。通过分析可知，当受扰后风电机组附近的同步机为临界机组时，风电接入会恶化系统暂态稳定；当受扰后风电机组附近的同步机为余下机组时，风电接入会有利于暂态稳定。

Abstract：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.
