Abstract

A power generation system is disclosed. The power generation system includes an electrical converting device and a repowered portion connected to the electrical converting device. The repowered portion includes a reciprocating internal combustion engine and a gearbox. The reciprocating internal combustion engine is connected to the gearbox by a first connecting structure. The gearbox is connected to the electrical converting device by a second connecting structure.

Claims

a gearbox,

first connecting structure, and

second connecting structure, wherein the non-originally-installed reciprocating internal combustion engine is connected to the gearbox with the first connecting structure;

removing the originally-installed internal combustion engine from the electrical converting device; and

repowering the power generation system by

connecting the repowered portion to the electrical converting device by connecting the gearbox to the electrical converting device with the second connecting structure.

2. The method according to claim 1, wherein the first connecting structure includes:

a misalignment coupling, and

a torsionally resilient coupling connected to the misalignment coupling.

3. The method according to claim 2, wherein the first connecting structure further comprises:

a gearbox input of the gearbox connected to the other of the misalignment coupling and the torsionally resilient coupling.

4. The method according to claim 2, wherein the first connecting structure further comprises:

a clutch, overrunning clutch, constant- or variable-fill fluid coupling or torque converter, wherein the torsionally resilient coupling connected to one or more of the clutch, overrunning clutch, constant- or variable-fill fluid coupling or torque converter and the misalignment coupling.

5. The method according to claim 4, further comprising the step of:

utilizing the clutch, overrunning clutch, constant- or variable-fill fluid coupling or torque converter for selectively translating rotational movement produced by the reciprocating internal combustion engine to the electrical converting device by way of the gearbox.

6. The method according to claim 1, wherein the first connecting structure includes:

a flanged connection including a first portion extending from the reciprocating internal combustion engine and a second portion extending from the gearbox, wherein the first portion is flanged to the second portion, and

a torsionally resilient coupling arranged within one or more of the first portion and the second portion.

7. The method according to claim 6, wherein the first portion is a flywheel housing, wherein the second portion is a gearbox input housing, wherein the torsionally resilient coupling is connected to

an output device of the reciprocating internal combustion engine, wherein the output device is arranged within the flywheel housing, and wherein the torsionally resilient coupling is also connected to

a gearbox input of the gearbox, wherein the gearbox input is arranged within the gearbox input housing.

8. The method according to claim 1, wherein the first connecting structure further comprises:

a torsionally resilient coupling,

an output device of the reciprocating internal combustion engine connected to the torsionally resilient coupling, and

a gearbox input of the gearbox connected to the torsionally resilient coupling.

9. The method according to claim 8, wherein the first connecting structure includes:

a clutch, overrunning clutch, constant- or variable-fill fluid coupling or torque converter coupled to the gearbox input.

10. The method according to claim 9, further comprising the step of:
