摘要
电力系统是一个多时间尺度的大规模非线性系统 ,其稳定性分析非常复杂。为提高稳定计算的效率 ,对复杂的电力系统模型进行化简 ,以实现系统化降阶非常必要。文中以电力系统物理电路为基础 ,导出了一个计及电磁快动态的电力系统奇异摄动模型。推导中 ,以感应电动机并联线性阻抗为负荷模型 ,并考虑了线路充电电容与负荷补偿电容。该模型是一个标准的双时间尺度模型 。
Power system stability analysis is extremely complex due to its multi-time scale nature, high dimensionality and non-linearity. For improving the efficiency of power system stability analysis, it is necessary to study tow-time scale dynamic models of power systems and relevant model reduction. A singular perturbation model incorporating fast and slow electromagnetic transients is derived based on physical circuits of power systems. The load model is treated as an induction motor in parallel with linear impedance, and line charging capacitance and compensation capacitors are also considered. The models derived in this paper lay the modeling foundation for performing systematic model reduction of power systems.
