Abstract
A method of monitoring quality of a control circuit in a power plant is provided. The quality of the control circuit is continuously assessed by determining characteristic quantities describing the quality by applying a plurality of testing methods suitable for describing dynamic properties of the control circuit to current operating data originating from the instrumentation and control equipment of the power plant, and by evaluating the characteristic quantities.
Claims17
A method of manufacturing a rotor for an electrical machine, comprising:
- providing a hollow metal cylinder;
- and
- plastically deforming the hollow metal cylinder permanently to a predetermined shape and to a predetermined size;
- providing a pressing unit arranged inside or around the cylinder;
- and
- applying a pressing force via the pressing unit to at least at of an inner or outer,
- wherein the pressing force is applied while the hollow metal cylinder is arranged inside a cavity of an mould element, and
- wherein the mould element comprises a matrix structure, in particular comprises a protrusion, which corresponds to a predetermined texture on an outer wall of the rotor.
