Article: BSA-based analysis of three-phase standalone asynchronous generator using two-port network Journal: International Journal of Power Electronics (IJPELEC) 2022 Vol.16 No.3 pp.385 - 398 Abstract: This paper presents the analysis of steady-state behaviour of a three-phase standalone asynchronous generator (SAG) supplying three-phase load based on binary search algorithm (BSA). The concept of two-port network is used to model the generator system along with the load. Two model equations developed from the modelling of SAG are solved by BSA to get the frequency (a) and magnetising reactance (Xm). The performance equations are formed with the help of frequency, magnetising reactance and magnetising characteristics of the machine to understand the steady-state behaviour of SAG. The waveforms of generated voltages and currents in the generator are also investigated and their corresponding harmonic contents are recorded. The simulated results are verified through the experimentation, and it shows that the experimental results closely agree with the simulated results. The BSA-based analysis of three-phase SAG is easier, more efficient and accurate. Inderscience Publishers - linking academia, business and industry through research

Abstract: This paper presents the analysis of steady-state behaviour of a three-phase standalone asynchronous generator (SAG) supplying three-phase load based on binary search algorithm (BSA). The concept of two-port network is used to model the generator system along with the load. Two model equations developed from the modelling of SAG are solved by BSA to get the frequency (a) and magnetising reactance (X_m). The performance equations are formed with the help of frequency, magnetising reactance and magnetising characteristics of the machine to understand the steady-state behaviour of SAG. The waveforms of generated voltages and currents in the generator are also investigated and their corresponding harmonic contents are recorded. The simulated results are verified through the experimentation, and it shows that the experimental results closely agree with the simulated results. The BSA-based analysis of three-phase SAG is easier, more efficient and accurate.
