Study On the Decentralized Output Feedback Excitation Controllers in Multimachine Power Systems:Part 2, Coordinated Selection of Weighting Matrix

本文以物理分析为依据,提出了一种多机电力系统分散最优励磁控制器状态权矩阵选择方法。该方法紧密地结合了电力系统实际,考虑了电力系统对励磁控制的基本要求,能够同时有效地改善电力系统的阻尼特性和提高电力系统的静态稳定性。

Based on the physical analysis, this paper proposed a new method for selecting the states weighting matrix in the decentralized optimal excitation control of multimachine power systems. The method is fully combined with the practice of power systems and has considered the basic requirements for excitation control to power systems. With this method, the damping characteristic and the steady state stability of power systems can be considerably improved.
