- a selection module 170 BP , 170 HP designed to directly receive a exchange instruction G' BP , G' HP , called direct, for example coming from the central computer 106, and to supply it selectively to the control module 140 BP , 140 HP , in place of the exchange instruction GBP*, GHP* provided by the 120BP, 120HP module.
- the power exchanged by the electromechanical converter 150BP, 150HP considered is directly regulated by the direct exchange setpoint G'BP, G'HP.
- only the 170HP selection module is activated.
- FIG. 10 repeats Figure 9 in the particular case where the exchange instructions GBP*, GHP* are power instructions to be exchanged PBP*, PHP* and where the evaluations PBP°, PHP° of the powers exchanged PBP , PHP are also the power instructions to exchange PBP*, PHP*.
- the modules 170BP, 170HP receive power instructions to exchange P'BP or P'HP.
- the 200 BP , 200 HP modules are designed to calculate the setpoint desired power to be exchanged P BP **, P HP ** from the sharing setpoint S, from the evaluation P BP °, P HP ° of the power exchanged P BP , P HP on the other side, and if necessary the evaluation P BP °, P HP ° of the power exchanged P BP , P HP of the side considered.
- the 120 HP , 120 BP modules then further comprise a 1100 BP , 1100 HP module designed to calculate a desired exchange setpoint G BP **, G HP ** from the desired power setpoint to be exchanged P BP **, PHP **.
- the comparators 201 BP , 201 HP are then designed to calculate an error between the desired exchange setpoint G BP **, G HP ** and the exchange setpoint G BP *, G HP *, and the correctors 202 BP , 202 HP (always preferably zero static error) are designed to calculate the voltage correction ⁇ VBP, ⁇ VHP from the error.
- the regulation of the errors ⁇ PHP*, ⁇ PBP* of the PHP*, PBP* instructions can be replaced by a regulation of the differences of these errors ⁇ PHP*, ⁇ PBP* .
- the bus voltage VDC drifts.
- the desired instructions G HP **, G BP ** are for example exchanged via the communication modules 100 HP , 110 BP .
