摘要： The invention lies in the field of current stabilisation in a power generation system comprising a plurality of elementary power groups connected in parallel. It relates to a control system for regulating the elementary power groups.
According to the invention, the control system comprises a global current control system (510) and a plurality of local current control systems each associated with an elementary power source of the power generation system. The global current control system (510) comprises:
▪ a divider (511) arranged to deliver a fixed current set point I n_fix ,
▪ a correction unit (512) arranged to deliver a variable current set point I n_var and to take either a steady state or a transitory state, the variable current set point I n_var being determined as a function of a correction signal S corr in the transitory state,
▪ an adder (513) arranged to deliver a global current set point I n _ glob as the sum of the fixed current set point I n_fix and the variable current set point I n_var , and
▪ a scenario management unit (514) arranged to detect when the state of at least one elementary power source (220 1 -220 N ) switches from an OFF-state to an ON-state, or vice versa, to determine the correction signal S corr and to trigger the transitory state of the correction unit for a predetermined transitory period τ trans when a change of state is detected.
