An intelligent support system for the analysis of power system transients
Electromagnetic transient programs such as EMTP are extensively used for simulating fast transient effects in electric power systems. However, these programs are not easy to use for the following two reasons. All of them require a high level of technical expertise to apply them properly. Most of them are not user friendly. This paper presents an intelligent system to support EMTP simulation. The intelligent support system is composed of three stages. First, the support system selects a base case from a case database, to be modified to meet the user's requirement. Second, the expert system checks the syntax and validity of the new case data. Finally, the EMTP solution is checked to see whether the chosen models are appropriate for the frequencies contained in the solution, for the degree of imbalance, and for other criteria. If they are not appropriate, better models will be recommended to the user.
