RT Journal Article T1 Final implementation of SEACON: new scope and new open system platform. A1 Mahou, A L A1 Soto, F J A1 Pastor, G A1 Corera, J A1 Criado, R A1 Ferrer, V A1 Martin, J A1 García-Santesmases, J M AB SEACON is a hybrid (heuristic & algorithmic)expert system for contingency analysis and preventive or corrective control of the transmission network, that has beenrecently redesigned to implement new end user requirementsand to increase its performance. This paper describes themain results and the operational experience from thedevelopment and implementation of a new system based onthe initial idea. Software reuse strategies became capital in this project. The new design includes advanced functionalities demanded by the practical use of the former system. Because of the high performance of the new system (up to fifteen times faster than the original) and its friendly user interface, SEACON has become a very valuable tool among dispatchers.SEACON is in operation in the Red Electrica’s NationalControl Centre and in Iberdrola’s Central and RegionalControl Centres, dealing with transmission and subtransmission networks (ranging between 4OOkV and66kV), attached to the on-line state estimators and screening over 2000 possible contingencies. Results are presented using natural language, and a client-server scheme provided for corporate access.
