| Abstract: |
| A CHIL（Controller Hardware-In-the-Loop） simulation system based on RTDS（Real-Time Digital Simulator） is established for the grid-connected inverter. The cause of system time-delay and its composition are studied and the effect of time-delay on the simulation system in its stability，precision and bandwidth is analyzed. The improved discrete Fourior transform algorithm is proposed to compensate the time-delay for improving the system stability and simulation accuracy. Theoretical analysis and experimental result prove the effectiveness of the proposed method. |
