Abstract

In this presented work, terminal voltage and reactive power control at the different conditions of load changes of synchronous generator in the AVR system is presented. To improve the step response of the alternator terminal voltage proportional integral derivative controller is carried out with optimization technique as Flower Pollination Algorithm (FPA) to optimally tuned the parameters of PID controller. The AVR system response with proposed FPA-PID controller is found to be better and compared that of with controllers in literature (42 in number). The performance is compared in terms of peak value, settling time and performance indices like ITAE, ISE and IAE. The robustness analysis of the proposed FPA based PID controller is considered for 156 plant conditions and varying time constants parameters as ±20% system conditions. The system stability with proposed FPA optimized PID controller also analysed in the form of eigenvalue, damping factor and frequency of oscillations.
