摘　　要：分析了华东电网发生元件故障后典型的潮流转移模式,将大面积潮流转移的复杂问题模型化,并寻找制约电网安全的最重要的热稳定约束,以此估算关键传输通道的极限传输容量。算例表明,该方法能帮助电网运行人员掌握电网的薄弱环节,提供传输通道的传输能力,对于提高电网运行水平和事故处理能力具有辅助作用。This paper analyzes the typical power flow transfer mode in the event of component failures in East China Grid. The complex large-scale flow transfer is modeled, and the thermal stability constraint, the most important con- straint of power grid security, is located, thereby, tO estimate the total transfer capability of the key transmission channel. Numerical example shows that the method can help the power grid operation staff take control of power grid vulnerabilities, and provide transmission channel with transfer capability, supportive for improving the power grid op- eration and contingency handling.
