StatCom´s B-Spline Neural Network Control

The b-spline neural net is a convenient tool to execute the power system voltage control, with the possibility of carrying out such task on-line. The controller´s design simplicity and its performance compared with the conventional PI controller are shown, specially those related with the overshoots and control signals quality, impacting directly into the controlled variable response and having quieter behavior than that of the PI control. With this neural control the possibility to implement the on-line control is potential due to its relative simple and fast calculations, thus representing a great help for the control. This paper is aimed to exhibit the performance of the static compensator (StatCom) as a mean for controlling the power system voltage magnitude on those buses surrounding the neighborhood where the StatCom is embedded. Results show the technique´s possibilities on a multi-machine power system
