The method performs active power perturbation analysis respectively on the stable equilibrium point of pre-fault system, the trajectory of fault-on system and transient stability of post-fault system.

应用暂态能量函数分析给出了注入空间上的实用动态安全判据，以此来量化暂态稳定性指标，从而实现对事故后系统的有功功率小扰动分析。

Lastly, the perturbation boundary element method is verified against the analytical solution and is applicable to transient pressure analysis of arbitrarily shaped reservoirs.

与解析方法的对比表明，本文的扰动边界元方法计算精度很高，适用于任意形状非均质油藏的不稳定压力动态分析。
