AVR-PSS Generator with Fuzzy Logic Controller and Conventional Damping of Low-Frequency Oscillations

A generator has several control options to improve the effectiveness of dampening operations against oscillations. A power plant’s conventional AVR and PSS controller technology aims to stabilize the operational system. Applications of fuzzy logic control are the foundation of one method employed. To assess the performance of these two controls and ascertain the features of oscillation damping response time, an application software-simulated system research was conducted using a mix of traditional AVR and PSS and fuzzy logic. Different Conventional and fuzzy logic-based AVR and PSS combinations compose the simulation setup. The simulated system reaction time of the prime mover drive starts at t = 2 s, and the electrical excitation starts at t = 18 s, as observed on a particular problem, electrical power (Pe) and terminal voltage (Vt) output variable. The optimal setup is AVR-FLC with PSS-C combo, meaning that with the continuous steady-state system, the terminal voltage overshoot response is 1.47 percent, the electrical power overshoot is 2.23%, and the damping ratio is 0.134. It is demonstrated through simulations that the stabilizing equipment of two generators may be used using a fuzzy-based system when each inference is constructed independently to exhibit the worst performance-even instability.
