The invention provides a double-circuit power supply short-circuit protection circuit and method for an unmanned aerial vehicle power distribution system. Double-circuit power supply is adopted for electric equipment. The solid-state power controller is used for realizing short-circuit protection action in a hardware mode, so that the timeliness of short-circuit protection is improved; the isolation diode is arranged at the tail end of the power supply and distribution line close to the electric equipment, so that the accuracy of short-circuit protection is improved; the short-circuit protection strategy is formulated according to the importance of electric equipment and the working state of an unmanned aerial vehicle, the solid-state power controller is used for monitoring the state of a power supply and distribution line, and the solid-state power controller receives a query instruction of a power distribution system through a CAN bus and reports state information of the power supply and distribution line to the power distribution system. And the solid-state power controller receives a power distribution system control instruction through the CAN bus and executes the short-circuit protection strategy.
