Current Control of the Isolated Self-Excited Induction Generator using Shunt Active Filter

摘要: Abstract The Self Excited Induction Generator (SEIG) is an isolated power source whose terminal voltage and frequency are controlled by the excitation of capacitance or load impedance. This paper presents a method for calculating minimum using equivalent circuit approach analyzing steady state operation SEIG. A new strategy based on active filter (APF) controlling current quality self excited induction generator also presented in this paper. shunt was implemented three phase PWM inverter (VSI) connected to wind loads order compensate harmonics reactive power. PWM-VSI gate control signals derived from hysteresis band controller. proposed proved play important role give good dynamic response robust behavior upon changes parameters. investigation demonstrated that average can facilitate improvement quality. extracts fundamental (reference) components line conditioners nonlinear unbalanced loads. Power additionally maintains capacitor (of inverter) nearly constant without any external circuit. APF conjunction with controller performs perfectly under different transient conditions. simulation results have showed effectiveness scheme harmonic reduction Wind Generation.
