For the past few years, modular multilevel converter (MMC) has been gradually applied as a flexible interconnection node in medium-voltage AC/DC hybrid distribution networks. In case of a short-circuit fault on a medium-voltage AC distribution line, the MMC in V/f control mode needs to limit the short-circuit current and guarantee a high quality of supply to

Run-of-mine ore is usually too large to be useful for construction or metallurgy. Large particles must be reduced to specific sizes to either comply with aggregate sizing regulations, or facilitate mineral liberation; therefore, in the aggregates and mineral processing industries, run-of-mine ore is broken in crushing circuits by cone crushers.
