    Control Techniques in renewable energy Techniques de commande des systèmes à énergie renouvelable
    (University of M'sila, 2024-12-03) GHADBANE Ismail
    The integration of renewable energy sources such as solar, wind, hydro, and biomass into the power grid presents unique challenges due to their intermittent and variable nature. Effective control techniques are essential to optimize the performance, stability, and efficiency of renewable energy systems. The course highlights the importance of real-time monitoring, fault detection, and grid synchronization to ensure reliable energy production and distribution. Ultimately, effective control of renewable energy systems is crucial for the sustainable and efficient utilization of clean energy. Teaching objectives, Know the different electrical systems of electric actuators (motor + mechanical loads and static converters) , Be able to establish a simulation model of an electrical system including motor, power electronics and control - Be able to simulate a model in the Matlab/Simulink environment , Be able to size the correctors present in the controls of energy production chains

    Electric safety
    (University of M'sila, 2024-11-24) GHADBANE Ismail
    Electrical safety refers to the set of practices and measures implemented to prevent risks associated with the use of electricity, ensuring the protection of people, property, and electrical installations. It is essential in all environments where electricity is used, whether in residential, industrial, or commercial buildings. The main aspects of electrical safety include protection against electrical shocks. An electrical shock occurs when the human body comes into contact with a live electrical conductor. Safety is achieved through the use of protective devices such as circuit breakers, grounding systems, and residual current devices, which help prevent this type of risk. Electrical installations must be carried out in accordance with current standards and regulations, such as the NF C 15-100 standard. A poorly installed system can lead to short circuits, fires, or electrocutions. Electrical systems should be regularly inspected and maintained to detect any abnormalities (e.g., exposed wires, damaged equipment). Equipment must comply with safety certifications. Personal protective equipment (PPE): People working on or near electrical installations must wear suitable protective gear, such as insulated gloves, safety shoes, and protective eyewear. Training and awareness: Prevention also involves training workers and the general public in proper safety practices, such as never touching damaged electrical devices or cables and avoiding the use of faulty equipment. Fire risk: A short circuit or insulation failure can cause a fire. It is therefore crucial to install safety devices that disconnect the power in case of failure. In summary, electrical safety aims to prevent electrical accidents through proper design, installation, and maintenance of equipment, as well as by training users and ensuring the use of appropriate protective devices. The goal of this field is to inform future professionals about the nature of electrical accidents, methods for rescuing electrical accident victims, and to provide sufficient knowledge for properly sizing protection systems for both equipment and personnel working in industrial and other sectors that use electrical equipment.
