Expert systems and their application to power systems. I. Components and methods of knowledge representation

摘要

Up to the 1960s the analysis of power systems consisted principally of analogue models or simple mathematical models. Later the developments in and the widespread availability of computers resulted in numerical and interactive methods to perform power systems analysis and control. Numerical methods to analyse loadflow, steady-state and transient stability and so on came during this period of development. These numerical methods have one major drawback. The experience of the engineers or heuristics employed by human experts cannot be coded directly into conventional programs. The authors outline how emergence of expert systems in the 1970s started to challenge the concept of traditional thinking.
