The proposed research deals with the analysis of interconnected power networks when subjected to large disturbances such as the loss of a generating unit. The vast majority of analytical work on power system dynamics deals with system behavior in response to small disturbances. In such cases linearized analysis is appropriate. For large disturbances, nonlinear interactions can play an important role. The approach used in this research extends energy-based methods to account for modal interactions.

提出的研究涉及的分析互联电网受到大干扰时，如发电机组的损失。绝大多数关于电力系统动力学的分析工作都涉及系统对小扰动的响应行为。在这种情况下，线性化分析是合适的。对于大扰动，非线性相互作用可能起重要作用。本研究中使用的方法扩展了基于能量的方法来解释模态相互作用。
