INTELLIGENT DATA APPLICATIONS TO POWER-SYSTEMS

Power systems change like developing organisms. Their world consists i n the complex structures of substation configurations and connective t opology, filled with a stock of objects of rather diverse semantics. I n power system control, in order to avoid re-programming at any amendm ent, this intelligence has to be expressed by data. Conventional data bases express real world semantics by data structures and describe rea l world structures semantically. Thus, reality's complexity and divers ity transforms into a multiplicity of listings and relations, entailin g high preparatory effort and poor access. Applying a data syntax, it becomes possible to handle a high dimensionality of data semantics and to express complex structures within one consecutive and dense data-t ent, thus, to invert the conventional approach and to gain much more e fficient ways in data handling and access. The GDL-data system develop ed on this basis is practically applied in a stand alone training simu lator and for the connection of expert systems in real time operation.
