Control method of a generator

A method of controlling a generator comprising an inverter provided with electronic switches which, controlled on the basis of instantaneous cyclic ratios αabc, enable said inverter to deliver to an electrical distribution grid an electrical power Pabc at an AC voltage Vabc, termed the source voltage, and an AC current Iabc, termed the source current, said voltage Vabc and current Iabc having a frequency fabc, the inverter being controlled by a control law that comprises:

• a) an integration loop configured to evaluate a difference ε between the source current Iabc and a current Ir, termed the grid current, estimated by an observation loop and actually required by the electrical distribution grid;
• b) a correction loop which, as soon as the difference ε is greater than a difference ε*, termed the reference difference, controls the adjustment by the inverter of the instantaneous cyclic ratios αabc in such a manner as to reduce the difference ε to a value less than the reference difference ε*.
