Turbine helper drive apparatus
 A turbine helper drive apparatus includes a turbine for driving a load, a motor coupled to the turbine, and a power converter for controlling an output from the motor based on a predetermined power reference. The power converter controls the motor so that the motor performs either a motoring operation, wherein the motor drives the load together with the turbine, or a regenerating operation, wherein the motor serves as a load for the turbine to generate an electric power.
