ABSTRACT:
In conjunction with a method and apparatus for regulating the power of a steam power plant block, an improved method and an improved apparatus for restoration of a given throttling of the turbine inlet valves as a conclusion to a regulating process for stabilizing a sudden or abrupt elevation of the load set point is proposed by the invention. The necessary storage of fresh steam takes place without influencing the electrical output power or the regulating devices necessary for regulating it with the aid of a separate closed control circuit.
