摘要
针对2008年夏季江苏苏北电网发生较大变化的情况,对过江断面输送10 000 MW和12 000 MW电力时的苏北电网暂态稳定性进行了计算分析,并对苏北电网的安全稳定控制措施进行了介绍。结果显示,在安全稳定控制措施的作用下,2008年夏季苏北电网的暂态稳定性较好。
According to the great change happened in the north part of Jiangsu grid in summer 2008,the paper analyses the transient stability of the north part of Jiangsu grid at that time when the power flow at the cross-section of transmission lines over Yangtze river reaches 10 000 MW and 12 000 MW respectively,and introduces its security and stability control measurements.Simulation results show that the transient stability of the north part of Jiangsu grid is comparatively good with the help of the security and stability control measurements in summer 2008.
