Abstract
In load-frequency control loops of electric power systems, the use of purely integral controllers to eliminate steady-state frequency deviations is a well established practice. However, the use of controllers which have only integral action always make transient behaviour worse, as compared to proportional controllers. Integral action for steady-state error elimination should be introduced in parallel with proportional action, thus forming a Proportional-Integral (PI) Controller. In this work a systematic procedure for including and setting of PI controllers in load-frequency control systems is suggested. An example is included, in which the procedure is illustrated, and a comparison between the result obtained with a PI controller and that obtained with a purely integral controller is made. It is verified that the PI controller, besides eliminating the steady-state frequency deviation, gives a better transient behaviour. (author) 5 refs., 6 figs.
