Stady of the Algeria / Tunisia interconnection network stability by insertion a phase-shifting transformer 'PST'

For interconnection networks, stability and security of networks in each country are of major importance for companies of generation and transmission of electrical energy and an objective of several research laboratories. For obvious technical and economic reasons, it is not possible to build networks free of malfunctions; they are particularly exposed at least to natural aggressions like lightning. Networks are therefore affected by disturbances that might affect the equipment durability and the quality of service provided and despite the existence of many traditional technical methods of stability, one always look for new methods that can improve the service quality. For this purpose, we will try in this thesis to address this issue through initially a thorough description of the interconnection network Algeria / Tunis then using the recorded incidents statistics, we focused our study on the disturbed line 220KV between AL Aouinette and Tajerouine with a proposed solution is to install a power transformer-type shifter "PST"
