Sequence analysis based DSP controller for Dynamic Voltage Restorer (DVR)
2008 IEEE Power Electronics Specialists Conference, 2008 The paper examines the behaviour of a dynamic voltage restorer (DVR) under balanced/unbalanced supply voltage sag condition, and restricted DVR injection capability (e.g. limited to 50% of the supply voltage injection). Sequence components of the supply voltage are extracted to generate the reference injected voltage for the DVR. The control determines
