| Abstract: |
| The topology and operational principle of parallel-type MLCR-CSC(Multi-Level Current Reinjection Current Source Converter) as well as its advantages are introduced. Its control model is built up,based on which the MLCR - CSC STATCOM working model is set according to the operational characteristics of STATCOM and simulated with PSCAD/EMTDC. The dynamic and static waveforms of system voltage and current are analyzed,and the influences of model parameters on the performance of STATCOM are discussed. Simulation results show the excellent performance of MLCR-CSC STATCOM and the feasibility of proposed control strategy. |
