A supply pump actuating turbine, in particular for a power plant, that includes at least two jet sectors for introducing a working gas into the turbine, a line system for connecting the at least two jet sectors to at least two different sources of working gas, and a valve arrangement for setting the supply of the jet sectors with the working gas from at least one of the sources. The valve arrangement and the line system are designed in such a way that at least three operating states can be set: a first operating state, in which all the jet sectors are supplied with the working gas of the first source, a second operating state, in which all the jet sectors are supplied with the working gas of the second source, and a third operating state, in which at least one of the jet sectors is supplied with the working gas of the first source and at least one other of the jet sectors is supplied with the working gas of the second source.

What is claimed is: 1. A supply pump actuating turbine comprising: at least two jet sectors configured to introduce a working gas into the turbine, each jet sector having an inlet to the turbine and the turbine being configured to drive a feed water supply pump of a steam generator; a first source of working gas; a second source of working gas; a line system connecting the at least two jet sectors to the first and second sources; and a valve arrangement configured to adjust a supply of the working gas to the jet sectors from at least one of the first and second sources according to at least three operating states, including: a first operating state, wherein the at least two jet sectors are supplied with the working gas from the first source; a second operating state, wherein the at least two jet sectors are supplied with the working gas from the second source; and a third operating state, wherein at least one of the jet sectors is supplied with the working gas from the first source and at least one other of the jet sectors is supplied with the working gas of the second source. 2. The supply pump actuating turbine as recited in claim 1, wherein the line system includes a first source line connected to the first source, a second source line connected to the second source, a connecting line connecting the first source line to the second source line, and first and second sector lines each connecting one of the at least two jet sectors to a respective one of the first and second source lines, and wherein the valve arrangement includes a coupling valve disposed in the connecting line for opening and shutting off the connecting line. 3. The supply pump actuating turbine as recited in claim 2, wherein the valve arrangement includes a setting valve disposed in the first source line and configured to adjust a quantity of the working gas. 4. The supply pump actuating turbine as recited in claim 2, wherein the valve arrangement includes a setting valve disposed in the second source line and configured to adjust a quantity of the working gas. 5. The supply pump actuating turbine as recited in claim 2, wherein the valve arrangement includes a nonreturn valve arrangement disposed in the second source line and having a nonreturn valve configured to shut off a gas flow directed toward the second source. 6. The supply pump actuating turbine as recited in claim 2, wherein the valve arrangement includes at least one of a quick-action closing valve disposed in each of the first and second sector lines and configured to quickly shut off the respective sector line, and a setting valve disposed in at least one of the first and second sector lines and configured to adjust a quantity of the working gas. 7. The supply pump actuating turbine as recited in claim 2, wherein the at least two jet sectors includes a first, a second, and a third jet sector, wherein the supply pump actuating turbine further includes a third sector line connecting to the third jet sector, and wherein the second and third sector lines have a common source portion connected to a respective one of the first and second source lines and wherein the second and third sector lines each have a sector portion connecting a respective one of the second and third jet sectors to the source portion. 8. The supply pump actuating turbine as recited in claim 2, wherein the coupling valve is a motor valve. 9. The supply pump actuating turbine as recited in claim 2, wherein the coupling valve is configured to adjust a quantity of the working gas. 10. The supply pump actuating turbine as recited in claim 1, wherein the first source is a steam line leading expanded steam from a high-pressure turbine via a resuperheating stage to an inlet of a medium-pressure turbine. 11. The supply pump actuating turbine as recited in claim 1, wherein the working gas of the first source is cold resuperheated steam. 12. The supply pump-actuating turbine as recited in claim 1, wherein the second source includes a bleeding point of a medium-pressure turbine disposed between an inlet and an outlet of the medium-pressure turbine. 13. The supply pump actuating turbine as recited in claim 1, wherein the working gas of the second source is a bleed steam of a medium-pressure turbine, the bleed steam being extracted between an inlet and an outlet of the medium-pressure turbine. 14. The supply pump actuating turbine as recited in claim 1, wherein the supply pump actuating turbine is for a power plant.
