中文摘要：

提出一种新型的戴维南等值参数计算方法。该算法能够解决传统戴维南等值参数求解方法中存在的等值系统内部发生扰动时,传统算法无法求解戴维南等值参数的问题及参数漂移问题。通过对传统算法的分析,提出基于泰勒展开式的Taylor算法,综合考虑系统中的非线性因素并建立校正机制,使得算法在复杂系统运行情况下表现出良好的准确性与稳定性。在3机9节点系统与IEEE 39节点系统中的仿真证明了所提算法的有效性。

英文摘要：

A new algorithm for tracking Thevenin parameters is proposed in this paper. The algorithm solves the problem that traditional algorithm for tracking Thevenin parameters is not applicable if power system suffers system side disturbance or parameter drift. With analysis of traditional algorithm, Taylor algorithm based on Taylor formula is proposed. Consideration of nonlinear factors and modified coefficient e improves accuracy and robustness of the proposed algorithm. Effectiveness of the algorithm is demonstrated with a 3-generator 9-bus system and IEEE 39-bus system.
