Optimisation Study of Generator Excitation System Based on Control Methods
In order to solve the low-frequency oscillation problem,the study constructs the Hefejung-Phillips model to analyse the hysteresis characteristics of the excitation system,and then uses the particle swarm optimization algorithm to improve the phase parameters of the power system stabilizer,and designs the PSO-PSS software.Finally,a global fast terminal sliding mode excitation control method is studied and designed to achieve the optimisation of the generator excitation system.The research results show that the GFTSM controller can stabilise the excitation system Is after the disturbance is generated.In summary,the PSO-PSS software proposed in the study has more excellent control capability with the GFTSM controller.
