PIDF Auto Tuning Control System (AVR) In Power System Stability Analysis Abdal-RazakShehab

This work aims to develop a controller based on auto tuning 0f PIDF to simulate an automatic voltage regulator (AVR) in transient stability power system analysis. AVR is an essential part of the synchronous generator and it is responsible for regulating the reactive power and voltage level under normal operating terms at various load levels. The modeled system consisted of theamplifier, exciter, sensor and proportional-integral-derivative-Filter (PIDF) controller. Simulationof the AVR system is carried out on the interface developed by Matlab GUI and the results are presented and compared with conventional (industrial PID) controller). In an attempt to cover a wide range of operating conditions, PIDF controller has been suggested as a possible solution toovercome the overshoot and slowly response which coupling design PID under different load condition that could present good performance in all operating points.
