ABSTRACT

The stability of tension is a restrictive factor of electrical energy transport on the high system tension. The evaluation of critical tension can be an indicator of the supervision of the security margin as well as of the stability. Nevertheless, this evaluation is difficult without resort to non-conventional methods. Other indicators are likely to give information on line about the point of collapse, as well as about the associated margin. Among these criteria, we note one that forwards the reactive power which is most frequently used. In this paper, we propose to study the tension stability as a slow phenomenon: A scenario of slow collapse of tension in the Tunisian network is considered. The critical tensions of level 225KV and the load model of the Tunisian network are equally identified. The defence plan against a slow collapse of tension using a mixed criterion of the tension and of its derivative is optimal.

Biograpgy:

A/Prof. Dr. Souad Chebbi has obtained her mathematics university bachelor’s degree 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 rearch 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. From that moment, she has been an associate professor in the same school which has changed its name to (ESSTT) high school of sciences and technology of Tunis. She is a member of the research team ATMAC at ESSTT specializing herself in energetic.
