Abstract:
A multi-unit power plant comprising:at least two power plant units, each of said at least two power plant units comprising: a generator-driving gas turbine; and a water steam cycle, the water steam cycle comprising: a generator-driving steam turbine; and a heat recovery steam generator, the heat recovery steam generator producing steam by heat exchange with hot exhaust gases from the generator-driving gas turbine, each heat recovery steam generator of the at least two power plant units having a saturated steam extraction point; a common feeder manifold, the common feeder manifold being common to a multitude of power plant units, the common feeder manifold coupling each water-steam cycle of the at least two power plant units with at least one first steam line, the at least one first steam line having a first shut-off device, the at least one first steam line extracting steam from the common feeder manifold, the common feeder manifold coupling with a saturated steam extraction point of each heat recovery steam generator of the at least two power plant units with at least one second shut-off device, wherein the at least one second shut-off device supplies steam to the common feeder manifold.
