A method for controlling a virtual generator including at least one renewable power source, an accumulation system including a power and/or energy reserve, an inverter and a control law, the virtual generator delivering an active P/reactive Q electrical power of voltage V and of current I to a microgrid, the voltage V and current I having a frequency f, the active P/reactive Q electrical power controlling, via droop control, the frequency f and the RMS voltage Vof the voltage V, respectively, the method including control of the virtual generator via the control law for which it carries out an adjustment of the active P/reactive Q power delivered to the microgrid, the adjustment being capable of compensating for a variation in the active/reactive power consumed by the microgrid.

Control method of a virtual generator

A control method brakes an electric motor connected to a voltage source. The method involves, in each cycle, the supply of current to the motor, with a delay t, at an angle &#x3b1;. The method includes a sequence such that, for every n cycle, the following steps are executed: a) determining the value of a variation in the resistance of the motor during the preceding n cycles of the voltage, b) comparing the value of the variation in resistance with a threshold resistance value R, c) increasing in the delay tif the value of the variation in resistance is lower than the threshold resistance value. The increase in the delay tis executed in accordance with a gamma command, where the angle &#x3b1; lies between 50&#xb0; and 80&#xb0;.

Control method for breaking an electric motor

A method for reconstituting a diagram of an electrical installation including a plurality of electrical elements connected to a power source via protective elements arranged in an electrical panel. The wired electrical elements of the installation are identified using the electrical panel. The tree structure of the electrical connections of the elements identified and the position of each element in the arborescence are automatically determined. An electrical diagram of the installation is deduced using the tree structure of the electrical connections and the position of each element in the arborescence.
