| 摘 要： | 针对动态分析频率稳定性计算费时、无法满足在线应用的难题,从静态分析的角度提出了一种快速评估频率稳定性的方法。该方法以故障后稳态频率或近似故障后稳态频率为评估指标,并以最大故障后波动频率为辅助指标。文中建立的3个指标数学模型均是代数方程,不包含微分方程。这些指标具有计算速度快、符合物理实际的优点,可以满足大型电网实际在线应用的需要。算例仿真结果验证了所提方法的正确性和有效性。 |

| Abstract: | Current dynamic analysis on frequency stability of power system often takes long time and cannot meet the demand of online application,to solve this problem,in the viewpoint of static analysis a fast method to assess frequency stability of power system is proposed. In this method,the post-fault steady-state frequency (PFSSF) or approximate post-fault steady-state frequency (APFSSF) are taken as assessment index and the maximum post-fault fluctuant frequency (MPFFF) as auxiliary index. Three models of the th... |
