Zusammenfassung:	The present application relates to a flexible direct-current receiving end alternating-current fault ride-through method and system, a computer device, a storage medium, and a computer program product. The method comprises: when a receiving end alternating-current fault signal of a receiving end alternating-current system is received, controlling a sending end converter (102) to switch to a capacitor voltage average value control mode (S202); acquiring a capacitor voltage average value of the sending end converter (102) and a capacitor voltage reference value of the sending end converter (102) (S204); determining a target sending end direct-current voltage reference value of the sending end converter (102) according to the capacitor voltage average value and the capacitor voltage reference value (S206); and controlling output power on a direct-current side of the sending end converter (102) according to the target sending end direct-current voltage reference value until the capacitor voltage of the sending en
