Abstract

A ne w fast approach to electrical power network analysis is presented in this paper. A description of a real-time multimachine power system simulator, developed at the University of Bath, will be given, which has been used rather than the more conventional fast decoupled load flow. The operation of the algorithms that have been developed as part of this simulator will be described, together with an explanation of how fuzzy set theory has been used for contingency screening and analysis, as well as the identification of system transient and dynamic instability. Results are presented for these fuzzy algorithms and compared with traditional numerical methods for the EEEE 57 bus system and a reduced British National Grid network. Finally, conclusions are drawn in the light of these results, illustrating the benefits that can be achieved with respect to accuracy and computational speed.
