This team Yu2020The year for dual feeder generators in the dual feeder generator isIEEE TRANSACTIONS on Power ElectronicsJournal (SCIOne District) Published a thesisAn Improved Direct Power Control for Doubly Fed Induction Generator(m88 sports bettingm88 live casino gamesimprovement of direct power control of dual -feeder generator).

For dual feed -sensitive generators(dfig)Back to back in the system(BTB)Converter，This paper designs a new type of voltage modulation direct power control(VM-DPC). ProposedVM-DPCIt is based on the static static coordinate system (αβ)。This method uses simple feedback and feedback structure，No Locking Ring andParkTransformation. Therefore, it can be easily inBTBImplementation in the converter. The proposed virtual machineVM-DPCIt is, it can bringdfigThe closed -loop system is M88 Online Live Casinoconverted into a linear m88 com live casino registertime -constant system，Analyze and design through a variety of linear control technology。Analysis based on feature value has proved that the method can ensure the stability of the index in both rigid grids and weak grid points。Simulation results indicate，proposedVM-DPCCompared with traditional vector control(VOC)A faster transient response. At the same time, it is withVOCThe same level has maintained a good stable stability。This paper also tested the proposedVM-DPCRasal that is lost in the condition M88 Online Live Casinoand parameters of distorting voltage。Last，in7.5 kw dfigThe system's experimental hardware prototypes are proposedVM-DPCThe control strategy has been verified in real time.
