【摘要】 本文对用微分-代数方程组(DAE)表示的电力系统注入空间上的动态安全域(DSR)的性质作了分析,并应用微分拓扑学理论证明了注入功率空间上的动态安全域边界不会打结,且是紧致的,基于相关不稳定平衡点法所定义的注入功率空间上的动态安全域内部无洞。在上述相关特性的指导下,本文用一个实际大电力系统为算例给出了注入空间动态安全域的实用几何描述。更多还原

【Abstract】 This paper analyzes differential topological characteristics of the dynamic security region (DSR) on injection space of electrical power system, which is usually represented as differential-algebraic equations (DAE). Results, by differential topology theories, show that the boundary of the DSR on injection space has no suspension and is compact, and there are no holes inside the DSR defined based on controlling unstable equilibrium point (UEP) method. According to these characteristics, an example on a bulk power system is provided to give the practical geometric description of the DSR on injection space.更多还原
