ABSTRACT:
A method for analyzing process signals of a technical plant, in particular a power station plant, having a system process subdivided into functional units, includes performing simplified signal tracing for a diagnosis or a forecast of a system state by checking if a process signal is a component of a functional unit, for each process signal and each functional unit. Thereafter, a degree of correlation between each two process signals is determined with the aid of the number of those functional units in which they are jointly a component. Subsequently, the process signals correlated with a prescribed process signal are represented as information elements that are positioned relative to one another in such a way that the distance between each two information elements represents the degree of their correlation.
