本文研究了使用相对增益阵列（RGA）进行电力系统小扰动稳定性分析的可能性。 RGA 过去已成功用作化学和过程工程中多变量、分散控制相互作用的稳态测量。将 RGA 在识别机电模式和选择 PSS 放置最佳位置方面的有效性与使用传递函数留数、特征值和参与因子的传统方法进行比较。案例研究使用了两种不同的多机电力系统。本文清楚地指出了为此目的使用 RGA 的局限性和优点。
The paper investigates the possibility to use relative gain array (RGA) for power system small-disturbance stability analysis. The RGA has been successfully used in the past as steady state measure of interactions for multivariable, decentralized control in chemical and process engineering. The effectiveness of the RGA in identifying electromechanical modes and selecting the optimal location for placement of PSSs is compared with the conventional approach that uses transfer function residues, eigenvalues and participation factors. Two different multimachine power systems are used for the case studies. Limitations and advantages of the use of RGA in this purpose are clearly indicated in the paper.
