An electric power supply system for an aircraft includes: a first electric source and a second electric source coupled together to supply electric power to a set of electrical loads, and a controller configured to acquire a piece of information on the current electric consumption consumed by the set of electrical loads; acquire a piece of information corresponding to a target ratio of the distribution, between the first and second electric sources, of the current electric consumption consumed by the set of electrical loads; perform frequency filtering of the current electric consumption to determine a transient consumption portion of the current electric consumption; determine control setpoints for the first electric source and for the second electric source in accordance with the target distribution ratio and with the transient consumption portion; and apply the control setpoints to the first and second electric sources.

Electric power supply system for an aircraft

A method for protecting a bipolar power distribution network supplied with power by an electric power source isolated from an electrical ground of an aircraft. The network includes a resistive protection device configured to be connected to the electrical ground and to the two phases of the network. The method includes the steps of receiving at least one voltage value on at least one of the two phases and/or at least one current value in the electrical ground, comparing the at least one voltage value with a first predetermined threshold value and/or the at least one current value with a second predetermined threshold value and controlling the protection device by changing its resistivity according to the comparison.
