Abstract:

The energy networks’ performance depends on the architecture of the network as well as on the energetic transfer command. From the fact of the complexity of this architecture which involves the energy network from many diverse resources of different natures ( production units, transformation stations, transport lines, consumption nodes…), the auxiliary network (communication network, protection plan, signalisation and observation network,…) and the human network (including all the levels contributes going from dispatching down to un-keep and maintenance) , it’s necessary to proceed to the situation’s global analysis by adopting a causal process including the different steps that could proceed any disturbance. It’s also necessary to analyse the incident’s dynamics; by exploiting the PIPO systematic method (The interventions’ planning per objectives), this causal analysis allows us to put into evidence the tree of problems illustrating the causes of high voltage electrical systems’ collapses. This tree constitutes a precious tool able to stop the intervention strategy in order to either avoid the black out or at least to reduce it on a given exploitation horizon.

Keywords: Collapse, preventive action, Curative action, OOPP method, Causal analysis.

A/Prof. Dr. Souad Chebbi, is an associate professor at the high school of sciences and technology of Tunis (ESSTT); she has obtained her mathematics university bachelor’s in1975. She has continued her superior studies in high teacher level school of technical education. Her first level university studies have ended up by a master’s degree in electrical engineering with good distinction in1980. Afterwards, she has obtained her diploma of extensive studies in electronics in 1981 with very good distinction ( in the same school), the research theme that has been treated in order to obtained this diploma was the study of the static stability of mono-machines’ network. She has also prepared a doctorate thesis in electrical engineering which was directed by professor Ribbens-Pavella of Montefiore institute in Liege-Belgium. The research theme was related to the  transitory study of the big electrical networks. The thesis has been held at the high teacher level school of technical   education in Tunis in1983, with very honorable distinction.. She is a member of the research team ATMAC at ESSTT. Her activities’ supervising: is the framing of some DEA (master degree) and Theses. She was invested in the safety  of the electrical supply networks’ study and the energy management

Chokri Bouchoucha, has passed his mathematics university bachelor’s with approximately good distinction, in 1997, he has obtained his engineering diploma in electrical engineering from the national school of engineering in Monastir (ENIM). In 2002, he has obtained his obtained his diploma of extensive studies in automation production engineering from the school of sciences and technology of Tunis (ESSTT). From that moment, he has been an engineer of networks studies, working in the Tunisian Society of Electricity and Gaz. He is also a departmental manager in network functioning and member of Maghreb committee of electricity (COMELEC)-sub-group of studies. At the moment, he is preparing a thesis on the securizing systems of electrical networks within the team ATMAC directed by Professor Mohamed Annabi.
