Control apparatus for large power supply systems having a multiplicity of small, decentralized and possibly volatile producers

Abstract

Provided is a control apparatus for determining a secondary/tertiary control power of a particular decentralized producer in a power supply system having a multiplicity of power producers, in which a subtractor is present such that a deviation of the locally measured or estimated frequency from the mains frequency is first of all determined, in which an amplifier is present, downstream of which an integrator with a limiter is connected, which, in addition to integration, ensures that a secondary/tertiary control power formed at the output of an integrator is limited, and in which the amplifier has a dead band, and/or the output of the integrator with the limiter is negatively fed back to the input of the integrator with the limiter via a feedback unit in which multiplication by a factor is carried out.

Dependencies are inferred from the claim text.
