Power system digital simulation and its development

The digital simulation of power systems has proved to be an effective tool for research, testing and operator training of power systems. This paper discusses the definition, classification, characteristics and application of the system simulation. Then the prospect of applying the digital simulation to the research, testing and operator training of power system is expounded. Improvement of the existing power system simulation software for research and development of new simulation software for real-time testing and operator training simulation will be of the main task. New technologies such as object-oriented methodology, artificial intelligence technique, new numerical methods and real-time simulation algorithm will offer important contribution.
