Abstract:
Automatic voltage regulator (AVR) is an essential component of power system that used to provide stable and reliable voltage profile from generator to load. Classical AVR may not effectively offer need stability and voltage quality required by a load connected to a generator because of its inability to manage the deviation of the output voltage from the desired voltage. Therefore, controllers are usually integrated with AVR. This is called AVR control system. However, most of the controller have used the popular proportional integral and derivative (PID) controller to enhance the transient performance of AVR and achieve stability and reliability in maintaining a given voltage level from generator to load. However, PID controller is usually propone to high oscillation and as such many modifications have been done in terms of tuning and structural realignment to its algorithm. In this paper, a PIDD controller was developed and used to enhance the transient performance of AVR in synchronous generator. An AVR system was modeled in MATLAB with PID controller and separately with PIDD controller. Simulation results revealed that the PIDD controller outperformed the PID controller by yielding settling time of 9.21 s against 13.8 s and overshoot of 4.85% against 18.3%.
