Abstract

A method of operating a train system for driving a mechanical driven equipment is disclosed. The train system comprises a hybrid gearbox connected between a power source and a load to be driven. The hybrid gearbox includes a lay shaft gear, which transmission ratio between the power source and the load and a motor-generator unit can be adjusted, to adjust the transmission speed ratio arranged, to balance the power generated by the power source and to improve the efficiency of the train system in a number of operating conditions.

Claims (6)

1. A method (8) for operating a train system (T) comprising the steps of: generating (81) power by a power source (2); transmitting (82) the power generated by the power source (2) through a drive arrangement (1) including: an input shaft (3) connected to the power source (2); an output shaft (5); and a hybrid gearbox (4) comprising layshaft gearbox (41), connected to the input shaft (3) and to the output shaft (5), and comprising a star carrier (413) configured to adjust the transmission speed ratio of the layshaft gearbox (41) between the input shaft (3) and the output shaft (5), and a speed ratio motor-generator unit (42), configured to control the rotation of the star carrier (413); driving (83) an equipment (L) connected to the output shaft (5); operating (84) the speed ratio motor-generator unit (42) to adjust the rotation of the star carrier (413) to set the transmission speed ratio of the layshaft gearbox (41) so as to adjust the speed (m0) and the torque (Co) at the output shaft (5) when the power sources (2) is operated at constant speed (u)j); and recovering (86) part of the power transmitted to the output shaft (5) and transform it in electrical energy to be injected in an electricity grid or battery packs (N) by a power balance motor-generator unit (6), operable as an electric motor, to adjust the speed (m0) and the torque (Co) of the output shaft (5), or as generator, to absorb at least part of the power transmitted to the output shaft (5), to generate an electric current.
2. The method (8) of claim 1, wherein the power source (2) is a double-shaft gas turbine, or an electric motor or a steam turbine, or a single shaft gas turbine, or a diesel engine or a gas engine
3. The method (8) of claim 2, comprising the step of Gas/Electric power balance (87) by the use of power balance motor-generator unit (6), connected to a battery system, as motor or generator, respectively delivering power to the output shaft (5) or absorbing part of the power transmitted to the output shaft (5) by the power source (2), thus enabling electric energy storage in a battery systems to build spinning reserve and cover gas turbines power surplus/deficit based on ambient conditions.
4. The method (8) of claim 1, comprising the step of Gas/Electric power bal- ance (87) by the use of power balance motor-generator unit (6) connected to an electric grid, as motor or generator, respectively delivering power to the output shaft (5) or absorbing part of the power transmitted to the output shaft (5) by the power source (2), to cover gas turbines power surplus/deficit based on ambient conditions
5. A computer program, comprising instructions which, when the program is executed by a computer (7), causes the computer (7) to carry out the steps of operating (84) the speed ratio motor-generator unit (42) and the recovering (86) of the method of claim 1 .
6. A computer-readable storage medium, comprising the instructions which, when executed by a computer (7), cause the computer to carry out the steps of operating (84) the speed ratio motor-generator unit (42) and the recovering (86) of the method of claim 1.
