Electrical energy is one of the essential energy carriers in energy management. It is becoming more and more important in new applications allowing to reduce the carbon footprint, for example in electric propulsion. Electrical energy is produced by high power production (thermal power plants) but also by more and more intermittent sources due to renewable energies (photovoltaic, wind power...). This electrical energy produced must be transported and distributed and the global management of the transport and distribution networks is a major constraint.

This unit of instruction will:

• To provide theoretical knowledge of modeling of the elements of production, transport and distribution of electrical energy.
• To define the three-phase sinusoidal regime, the quality of electrical energy and the study of unbalanced networks by symmetrical components.
• To allow the implementation of the modeling of transformers, inductive elements (neutral point coil...), synchronous alternators and asynchronous generators. It will give the experimental methods of characterization of these elements.
• To give the conditions of connection of the generators to the electric networks, the setting in parallel and the associated adjustments.
• To allow the establishment of models for lines and cables for electrical distribution. It will give notions of power management, of the impact of short-circuit in high power networks. The use of network software will illustrate the phenomena.

The energy transition is often associated with objectives for the implementation of production means from renewable energies (wind, photovoltaic, hydraulic...). The use of intermittent sources of energy generates particular constraints for the electrical transmission and distribution networks. This teaching unit will consist of three parts: a technological and theoretical part on the networks. A second part on the means of production and renewable energies, with a focus on wind energy. Finally, a third part will focus on the digital evolution of electrical networks: smart grids.

This unit of instruction will:

• Define the technology of all the elements of a HV and LV electrical distribution network.
• To provide the necessary knowledge to understand the functions and characteristics of electrical networks (architectures, overhead, underground, voltage levels, powers, transformers, alternators...) and
• To allow the choice and the implementation of devices according to the needs (insulation, protections, control...).
• Define the electrical safety rules for interventions allowing to understand and apply the consignment procedures.
• To allow to determine, to choose and to adjust the protections from the characteristics of the network and the equipments by explaining the calculation of the fault currents and the basic use of the professional software of calculation.
• To detail the choice of the grounding schemes answering a specification and given economic criteria, constraints of availability, quality...
• To make a state of the art of the means of storage of the electric energy and to present the use of the hydrogen as energy vector associated with the electric energy and the energy transition.
• Describe the means of production and develop the principle of conversion for wind and water power production.
• Introduce the methods of studying wind projects, analysis of the resource, regulations, the problem of connection and the impact on the environment.
• Introduce Smart-Grid and the use of internet and industrial networks in the protection and control of electrical networks.
