The embodiment of the utility model discloses flexible direct current converter topology suitable for multi -wind electric field inserts and is incorporated into power networks, the embodiment of theutility model provides an adopt in wind -powered electricity generation field side and does not control the rectifier bridge, showing the cost and the complexity of control that reduce flexible directcurrent system, be favorable to the access of multi -wind electric field, the busbar voltage that only requires the wind -powered electricity generation field remain stable can, can carry out the independent control to each contravariant bridge in the electric wire netting side, need not intercoordination, the degree of difficulty that the reduction was controlled, the embodiment of the utility model provides a need not the contravariant bridge at electromagnetic compatibility, high voltage insulation scheduling problem and undertakeing, and change and undertaken by the transformer, the engineering of being convenient for realizes, the embodiment of the utility model provides an in three -phase bridge contravariant bridge and do not control rectifier bridge simple structure, technology maturation, the moulding massing that can appear is produced according to the standard, reduces manufacturing cost. But whole transverter in time switches to the spare module when a module breaks down at design time redundancy design, improves system reliability.
