Zusammenfassung:	The invention discloses a start-stop control method for an offshore wind power flexible direct-current delivery system, and the method comprises the following steps: S1, starting an onshore converterstation, and entering the alternating-current side charging stage of the onshore converter station; S2, starting an offshore converter station, and entering the direct current side charging stage of the offshore converter station; S3, sequentially unlocking the onshore converter station and the offshore converter station, and entering an alternating current field electrification stage; and S4, closing the circuit breaker of an alternating-current field, and starting the fan of an offshore wind plant to be connected to a grid. The alternating current field of the offshore wind power flexible direct current sending-out system is a passive system, and offshore wind turbine grid connection requirements are combined, the start-stop control method for the offshore wind power flexible direct-current delivery system achie
