Robust PLL Algorithms for Grid Voltage with DC Offset voltages

  • 발행 : 2016.07.05

초록

This paper proposes the PLL algorithms with both the quadrature signal generator (QSG) and the positive-sequence calculator (PSC) in order to remove the effects of the three-phase grid voltage with dc offset voltages. The performances of the proposed method are verified with both the simulation result and the experimental result with 32-bit DSP.
