Voltage Sag Response of PWM Inverters for Variable-Speed Wind Turbines
2006
EPE Journal
Preserved Fulltext
The voltage sag response of PWM rectifiers is analyzed for a candidate dc-link voltage control system. It is shown that the voltage sag response is mainly determined by the dynamics of the dc-link voltage and the control system. PWM rectifiers are found to be robust against voltage sags, but the remaining grid rms voltage limits the maximum active power that can be delivered to the utility grid during voltage sags.
