摘要
Abstract
This paper introduced the topology and working principle of cascaded two-level(CTL) converters.The design of the cell capacitor and the buffer reactor was presented.A carrier phase shifted sinusoidal pulse width modulation(CPS-SPWM) strategy and voltage balancing control suitable for CTL were proposed.A simulation model of a practical engineering CTL of ±320 kV/1 000 MW and 39 level was built using the PSCAD/EMTDC software tool.The simulation result indicates the validity of CPS-SPWM for CTL and AC output harmonic was analyzed.关键词
