The invention provides a diode-based energy consumption device, a flexible DC power transmission system and a wind power generation system wherein the diode-based energy consumption device comprises: a first diode connected in series to a first path, the first diode being conducted in a direction from an energy consumption end to a grounding end; and the second diode is connected in series to the second path, and the first diode is conducted along the direction from the energy consumption end to the grounding end. According to the energy consumption device based on the diodes, the flexible direct current power transmission system and the wind power generation system disclosed by the invention, the impact of voltage and current on each device in the energy consumption device can be effectively reduced when the first path and the second path are alternately switched on and off by utilizing the one-way conduction characteristics of the first diode and the second diode; therefore, the requirement for voltage and
