This value was able to maintain the generator voltage output at the time of interference with settling time (ts) of 0.89594 and maximum overshoot of 25%. In this case, the AVR performance was changed by setting the root value in the characteristic equation so that the constants Kp = 0.016135, Ki = 0.01815 and Kd = 0.00359 were obtained. Matlab programming simulation results and Routh's criteria analysis showed that the PID controller was able to reduce oscillations occured and the system quickly returned to a stable condition even though there was a change in load (interference) by adjusting the P (proportional), I (integrative) and D (devirative) parameters. Below the underspeed frequency, set by potentiometer F, the generator voltage is controlled according a Volt per Hertz ramp. Automatic Voltage Regulator (AVR) Controller Design Analysis using Matlab program with simulink method using Routh’s Criteria. Your automatic voltage regulator is an important factor in the determination of your generator system’s performance and longevity as well as the technology that it is powering. In order for this incident to not occur, an AVR can be used to adjust the generator voltage according to the increase in reactive power. of AC generator excitation system, connect host stator winding and excitation winding, to provide precision output voltage of the closed-loop control. The AVR component of your Genset’s main function is to assert and sustain the appropriate voltage level range for your generator system’s alternating current.
Increased stator current can be overcome by increasing the generator voltage. Excessive reactive power can damage the generator stator windings due to increased stator currents.
The normal or abnormal condition of the power system leads to electrical voltage problems. But the increase in load that is not accompanied by additional capacity will cause the system to operate abnormally. In order to control such conditions and ensure protection from any kind of electric or fire hazards, you need to make sure that your generators Automatic.
Changes in load on electric power systems are unavoidable at all times.
