Abstract:
A power turbine control unit calculates, as a feedforward opening, the opening of a power turbine control valve (B) that controls the flow of exhaust gas supplied to a power turbine (23) from a main engine (22), on the basis of required on-board power and the load of the main engine (22), and outputs the feedforward opening to the power turbine control valve (B). A fuel injection control unit calculates, as a converted fuel injection amount, the fuel injection amount of the main engine (22) that corresponds to the output of a shaft generator/motor (35) during motor operation, and subtracts said converted fuel injection amount from the fuel injection amount supplied to the main engine (22).
