ABSTRACT:
A steam generating power plant includes a generator connected to a network, a steam turbine driving the generator, a steam bleeder line being connected to the steam turbine and having a load-dependently adjustable valve, a system having a superconducting magnetic energy accumulator and being connected electrically parallel to the generator, and a control unit. The control unit furnishes electrical power directly from the superconducting energy accumulator to level a power deficit lasting on the order of several seconds in the network and the control unit at the same time adjusts the valve to increase steam available to the steam turbine. A process for operating a steam generating power plant, an interlocking electrical network in combination with a number of steam generating power plants, and a process for operating the interlinking network in combination with the steam generating power plants, are also provided.
