摘要

本文研究了采用电力系统稳定器(PSS)、线性二次型调节器(LQR)和基于降阶观测器的最优控制器(ROOC)的单机无限母线(SMIB)系统在小扰动下的动态稳定性分析。通过Heffron-Phillip模型对发电机参数进行辨识。在额定负载条件下，分析了所提控制器的性能。通过特征值和时间响应结果进行分析。与LQR、PSS和无控制器相比，ROOC提供了更好的动态结果。

Dynamic Stability Analysis of SMIB System with PSS, LQR and ROOC

This paper describes the dynamic stability analysis of Single Machine Infinite Bus (SMIB) system with Power System Stabilizer (PSS), Linear Quadratic Regulator (LQR), and Reduced Order Observer based Optimal Controller (ROOC) for enhancement of dynamic stability under small disturbances. The generator parameters are identified through Heffron-Phillip’s model. The performance of the proposed controllers are analyzed at nominal load condition. The analysis is carried out through eigenvalues and time response results. The ROOC provides better dynamic results compared to LQR, PSS and without controller.
