Abstract (en)
[origin: WO2015039907A2] The invention relates to a method for testing an overspeed protection system of a single-shaft unit (1) which comprises a gas turbine (2), a generator (4) and a steam turbine (3) and which has a coupling (7) by means of which the steam turbine can be coupled to the single-shaft unit (1), comprising the steps: a) disengaging the coupling (7); b) operating the gas turbine (2) and the steam turbine (3) at the rated speed of the gas turbine and the steam turbine; c) increasing the mass flow rate of the steam introduced into the steam turbine (3) in such a way that the speed of the steam turbine (3) reaches a steam turbine threshold speed, the overspeed protection system being arranged in such a way that a first overspeed protection is initiated as soon as the speed of the steam turbine (3) reaches the steam turbine threshold speed; d) testing whether the first overspeed protection is initiated.
