| Abstract: Previous works in the field of power system stability adopting the concept of supplementary signal were mostly dedicated to stabilize all system modal instabilities. In this paper a study is made to identify the particular type of supplementary signal most-effective in increasing the damping introduced to the excitation system over a specific power system mode of instability. To this end, a series of MATLAB algorithms were developed and the results obtained yielded a set of supplementary signals to be introduced to the excitation of a single machine infinite bus-bar power system. The effect on increasing damping over a particular system mode is evaluated. The outcomes from extensive case studies confirmed the validity of the proposed approach. | ||
