A method of operating an internal combustion engine coupled to a generator in the event of a grid fault of a power supply grid connected to the generator, in particular in the event of a dynamic grid voltage drop, wherein the internal combustion engine includes a turbocharger having a compressor in an air feed duct of the internal combustion engine and an exhaust gas turbine coupled to the compressor in an exhaust gas duct of the internal combustion engine, wherein there is provided at least one bypass valve for bypass of the compressor and/or for bypass of the exhaust gas turbine, wherein upon or after detection of the grid fault the at least one bypass valve is at least temporarily actuated.

1. A method of operating an internal combustion engine coupled to a generator in the event of a grid fault of a power supply grid connected to the generator, wherein the internal combustion engine includes a turbocharger having a compressor in an air feed duct of the internal combustion engine and an exhaust gas turbine coupled to the compressor in an exhaust gas duct of the internal combustion engine, wherein there is provided at least one bypass valve for bypass of the compressor and/or for bypass of the exhaust gas turbine, wherein, upon or after detection of the grid fault, the at least one bypass valve is at least temporarily actuated,wherein ignition in the internal combustion engine is deactivated upon or after detection of the grid fault,wherein the ignition in the internal combustion engine is activated again after the grid fault disappears, andwherein the at least one bypass valve has a first position prior to detection of the grid fault, wherein, upon or after detection of the grid fault, the at least one bypass valve is set to an actuation position differing from the first position, and wherein the at least one bypass valve is set to a position differing from the actuation position and the first position after the grid fault disappears. 2. The method as set forth in claim 1, wherein the at least one bypass valve is opened to an actuation position which is further opened in relation to the first position. 3. The method as set forth in claim 1, wherein the at least one bypass valve is kept in the actuation position during a predeterminable actuation time. 4. The method as set forth in claim 3, wherein the at least one bypass valve is set substantially again to the first position after the predeterminable actuation time. 5. The method as set forth in claim 3, wherein the at least one bypass valve is closed after the predeterminable actuation time to a second position which is further closed in relation to the first position and is kept in the second position during a predeterminable time. 6. The method as set forth in claim 1, wherein the ignition in the internal combustion engine is activated again if a rotary speed of the internal combustion engine or the generator reaches a predeterminable rotary speed value and/or a relative phase angle change in the generator reaches a predeterminable value. 7. The method as set forth in claim 1, wherein the at least one bypass valve is closed to a second position which is further closed in relation to the first position after the grid fault disappears and is kept in the second position during a predeterminable time. 8. The method as set forth in claim 1, wherein, after the grid fault disappears, activation of the ignition and setting of the at least one bypass valve to a position differing from the actuation position takes place substantially at the same moment in time. 9. The method as set forth in claim 1, wherein, after the grid fault disappears, setting of the at least one bypass valve to a position differing from the actuation position takes place after activation of the ignition. 10. A method of operating an internal combustion engine coupled to a generator in the event of a grid fault of a power supply grid connected to the generator, wherein the internal combustion engine includes a turbocharger having a compressor in an air feed duct of the internal combustion engine and an exhaust gas turbine coupled to the compressor in an exhaust gas duct of the internal combustion engine, wherein there is provided at least one bypass valve for bypass of the compressor and/or for bypass of the exhaust gas turbine, wherein, upon or after detection of the grid fault, the at least one bypass valve is at least temporarily actuated,wherein the at least one bypass valve has a first position prior to detection of the grid fault, wherein, upon or after detection of the grid fault, the at least one bypass valve is set to an actuation position differing from the first position and is kept in the actuation position during a predeterminable actuation time, andwherein the at least one bypass valve is closed after the predeterminable actuation time to a second position which is further closed in relation to the first position and is kept in the second position during a predeterminable time. 11. The method as set forth in claim 10, wherein the at least one bypass valve is opened to an actuation position which is further opened in relation to the first position. 12. The method as set forth in claim 10, wherein the at least one bypass valve is set substantially again to the first position after the predeterminable actuation time. 13. The method as set forth in claim 10, wherein ignition in the internal combustion engine is deactivated upon or after detection of the grid fault. 14. The method as set forth in claim 13, wherein the ignition in the internal combustion engine is activated again after the grid fault disappears. 15. The method as set forth in claim 14, wherein the ignition in the internal combustion engine is activated again if a rotary speed of the internal combustion engine or the generator reaches a predeterminable rotary speed value and/or a relative phase angle change in the generator reaches a predeterminable value. 16. The method as set forth in claim 10, wherein the at least one bypass valve has a first position prior to detection of the grid fault, wherein, upon or after detection of the grid fault, the at least one bypass valve is set to an actuation position differing from the first position, and wherein the at least one bypass valve is set to a position differing from the actuation position after the grid fault disappears. 17. The method as set forth in claim 16, wherein the at least one bypass valve is closed to a second position which is further closed in relation to the first position after the grid fault disappears and is kept in the second position during a predeterminable time. 18. The method as set forth in claim 16, wherein, after the grid fault disappears, activation of ignition and setting of the at least one bypass valve to a position differing from the actuation position takes place substantially at the same moment in time. 19. The method as set forth in claim 16, wherein, after the grid fault disappears, setting of the at least one bypass valve to a position differing from the actuation position takes place after activation of ignition. 20. The method as set forth in claim 10, wherein the at least one bypass valve is opened substantially again to the first position after the predeterminable time. 21. The method as set forth in claim 1, wherein the grid fault is a dynamic grid voltage drop. 22. The method as set forth in claim 10, wherein the grid fault is a dynamic grid voltage drop.
