Abstract:

扰动后系统最低频率预测是电力系统频率安全稳定评估的重要内容.提出一种基于广域量测数据计算扰动后电力系统频率及其最低频率的预测方法.该方法对扰动后的系统进行线性化处理,利用扰动前、后系统的广域量测数据,建立扰动后系统的状态方程.算法中考虑了系统网络、负荷、原动机-调速系统对系统动态频率的影响.使用Arnoldi降阶方法,对系统状态方程进行降阶处理,形成低阶系统.求解降阶后系统的低阶状态方程,计算系统动态频率及最低频率.通过与PSS/E仿真结果比较,证明该算法能够准确、快速计算出扰动后的系统频率及其最低频率.分别使用扰动后25及50ms时刻的数据,仍能有效地计算出系统频率及最低频率,表明算法具有较好的鲁棒性.
