Electrical installation design and study of an industrial oil and gas project: application on EGPDF pipeline
(2019) Ouldammar, Bilal; Bouchahdane, Mohammed (supervisor)
The main purpose of this thesis is to introduce methods and standards of design, calculation and selection of electrical equipment and protection systems in an industrial oil and gas plant, application on EGPDF Pipeline. These calculations and selections are based on common international standards (IEC, BS, NF, AS, NZS…), also performed with the convenient computer software (AutoCAD, PVsyst, e-Design, CYMGrd, Pulsar designer) The project will constitute a high qualified training for real electrical engineering project in order to blend in a professional environment.
Health index assessment of power transformer

A Health index is a tool that processes service and condition data into a score which describes the overall health of an asset. The motivation behind this is to objectively and confidently assess the condition of power transformers so that reinvestment and maintenance decisions might be justified. This way, the technical lifetime of healthy assets might be safely increased, while risky assets can be identified and taken care of before they fail. Health indexing is particularly useful for evaluation of large transformer fleets, since it makes it easy to identify the assets most in need of additional attention. An important prerequisite for a health index to be useful is, however, that the availability of data is considered in the model design. A health index intended for use in Algeria will thus have to be customized to the data availability faced by most Algerian utilities and transformer users.
Study and implementation of Real-time testing with Hardware in the loop protection relays and power meters
(2020) Bentayeb, Yazid; Bouchahdane, Mohammed (supervisor)
Due to increasing need for power system protection functioning insurance and compliance to system needs for electrical devices protection, and their effect on the power system stability and customer services, protective relays and power meters needs to be tested to ensure compliance of the devices with the power system needs. Real-time simulator-based factory acceptance tests (FAT) are by now a necessary and well-established part of the process of developing and implementing new protection schemes by electric power utilities. This thesis presents hardware implementation of adaptive protection relay and power meters testing models based on real time simulators. The simulation tool used was Opal-RT OP5600 real time digital simulator. To emulate the actual environment where the test model could be used, a complete phasor network setup is established using actual devices, such as protection relays, power meters and current and voltage amplifier. A simulation models based on MATLAB/Simulink software were designed to perform real time simulation testing of the protective relays and power meters. The obtained test results describe the functional states of the tested devices. The results are compared to the standards expected results and limitations.
