Abstract
This paper proposes a sliding mode control method to be used in the dynamic voltage restorer (DVR) system for regulating voltages of three-phase loads. The voltages produced by the DVR’s inverter are provided by three sliding mode controllers. Each of them operates on a error resulting from the difference between the phase reference and the measured single-phase load voltage. The reference synchronization is carried out by a recursive least-square (RLS) algorithm. Moreover, a flag procedure is applied to assure that the DVR operates only on periods of time where system is in steady state. This is suitable for saving energy. The technique has been evaluated in Simulink for different sag conditions. Finally, an experimental setup of a DVR has been used to evaluate the method, and the results show the effectiveness of it.
