A new fast-converged estimation approach for Dynamic Voltage Restorer (DVR) to compensate voltage sags in waveform distortion conditions
International Journal of Electrical Power & Energy Systems(2014)
摘要
•An estimation approach is developed.•The approach detects symmetrical components of intended frequencies.•The approach identifies symmetrical components of unbalanced voltages in a network.•The approach is applicable in on-line and fast-responding applications.•A control scheme well-suited to DVR, provides compensating voltages using the approach.
