Improvement of Dynamic Performance in SEIG WECS by Using ANFIS Controller
No full textA new hybrid controller for the Self-Excited Induction Generator (SEIG) driven by the Wind Energy Conversion Scheme (WECS) was proposed in this paper. The dynamic stability of the control grid is essential for both user protection and system performance. There must be a full grasp of the effects of power system volatility to research and govern power systems. The suggested control systems were examined using frequency-domain approaches that focused on the nonlinear design of a device that is subjected to severe faults on a related bus, which was tested using time-domain strategies. In this paper, a novel 3-level inverter is designed and controlled by the ANFIS control for the Dynamic Response of the system at the load side. The ANFIS approach can be used to regulate a self-excited induction generator in this study. The design incorporates wind power to give on-grid electricity access. SEIGs are used to power wind turbines in this project, which generates alternating current (AC) for the grid. The system model uses a rotor reference frame and dynamic vector control for the machine reference model. Wind power voltage and active power are controlled by an ANFIS controller in the converter. The ANFIS controller's performance is evaluated in all abnormal scenarios, including the worst-case scenario. System modeling and simulation in Simulink-Matlab allow it to be used in SEIG configurations. Wind power system quality and stability are both improved by the ANFIS control unit, according to simulation results
Control of Self-Excited Induction generator based wind turbine using by IM controller
No full textThis paper focuses on the electrical generation part of a wind energy conversion system. After a brief introduction of the induction machine, the electrical generator used in this paper, a detailed analysis of the induction machine operated in stand-alone mode is presented. This paper shows the effect of magnetic saturation during self- excitation process in an isolated three phase induction generator, for a given capacitance and rotor speed value. When the steady state condition of a self-excited induction generator (SEIG) is attained, an increase of load causes a decrease in the magnitude of generated voltage and its frequency. The dynamic model of the SEIG system is developed using dq variables in stationary reference frame. For the validation of mathematical modelling, model of Matlab Simulink is developed and performed on three phase SEIG machine with the internal model controller (IMC). Simulation results of the self-excited induction generator driven by the variable speed wind turbine are presented in the last section of this paper. The process of voltage build up and the effect of saturation characteristics are also explained
