【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。
[Abstract]:A new method for calculating Thevenin equivalent parameters is presented. This algorithm can solve the problem of Tawenan equivalent parameter and parameter drift when the internal disturbance of the equivalent system exists in the traditional method of solving the equivalent parameters of Thevenin. Based on the analysis of the traditional algorithm, the Taylor algorithm based on Taylor expansion is proposed. The nonlinear factors in the system are taken into account and the correction mechanism is established, which makes the algorithm show good accuracy and stability in the complex system. Simulation results in 3-machine 9-bus system and IEEE 39-bus system show the effectiveness of the proposed algorithm.
