| 摘要 |
The invention relates to a steam turbine facility (10), e.g. for use in a solar power plant, comprising a main steam supply (12) for supplying high pressure steam to a main supply pipe (18); a high pressure turbine (20) drivable by steam fed from the main supply pipe (18) to an inlet (22) of the high pressure turbine (20); a low pressure turbine (28), rotationally coupled to the high pressure turbine (20), and drivable by low pressure steam extracted from an outlet (30) of the high pressure turbine (20) and fed via an intermediate pipe (32) to an inlet (34) of the low pressure turbine (28). According to the invention, the steam turbine facility (10) further comprises auxiliary operation means (60, 62, 65, 66) for maintaining turbine operation in a phase of degraded main steam supply, wherein the auxiliary operation (60, 62, 65, 66) means are designed to branch off auxiliary steam from low pressure steam driving the low pressure turbine (28), and to inject the auxiliary steam into the main supply pipe (18).
