Teaching power system stabilizer and proportional-integral-derivative impacts on transient condition in synchronous generator

Abstract

Understanding the concepts based on problem solving is not an easy methodology in teaching the impact of power systems stabilizer (PSS) on transient synchronous generator using MATLAB capability. Experiments conducted in simulating sessions play an important role in this teaching. This simulation can simulate power system stability behavior with reasonable accuracy in less time. This transient phenomenon of a power system utilizing synchronous generator and modelling by fully three-phase model with changes in stator flux linkages neglected is analyzed by employed single machine infinite bus taken to the power system. Whereas a power system stabilizer which consist of a wash-out circuit, two stages of compensation, a filter unit, and a limiter, is applied to control voltage and frequency of power systems in transient condition. Proportional-integral-derivative (PID) controller tuned by Ziegler-Nichols’s method is cascaded to conventional PSS in order to enhance the response time of system while providing a better result in damping for oscillation. This gives the clear idea about PSS and PID controller impacts on transient synchronous generator and its enhancement to the students of electrical engineering program, Institut Teknologi Nasional Yogyakarta.

Particle swarm optimization and Taguchi algorithm-based power system stabilizer-effect of light loading condition

“…Every solution in PSO is a bird in the search domain. Particles are the name for these solutions [12]. The fitness function that needs to be optimized determines the fitness values of all these particles.…”

“…It is an efficient and systematic way of determining optimum configuration of design parameters including performance cost and quality. Kadiman et al [12] has introduced an auto-tuning traditional PSS of proportional integral derivative (PID) structure as an extra controller to dampen low frequency oscillations and improve the system's dynamic performance.…”

Higher order model of synchronous generator

“…Various generator models have been developed [1]- [4]. For such analysis studies, the models of simple transient states based on the common method, such as the primary swing stability of electromechanical oscillation of the rotor, is useful but not suitable to envisage generator performance concerning control experiments; it creates dissimilar results with the measurements [5]- [8].…”
