Goals

The objective of the "Sizing and protection of electrical networks" unit is to describe the technological choices to size and operate the transmission, distribution and industrial electrical network. The protection means that are implemented in order to protect the network devices and people are also studied. The impact on these choices and methods related to the integration of renewables, storage and electric vehicles is also analyzed.

At the end of this module, students will be able to:
Know technical and economic rules of sizing electrical networks (transmission, distribution and industrial).
Select protections regarding the type of electrical network, the constraints it faces while complying with objectives of security and service quality
Be aware of the impact of new actors of Smart Grids (renewable energy producers or not, storage, electric vehicle) on the development of electricity networks.

Content

In order to get these skills, this module is divided into 4 classes.

  • The transmission network : development and operation
    This course will explain the issues of development of the transmission network, technical studies (hypotheses considered and possible solutions) as well as the economic justification of investments. A contractual part will address grid connection issues, the Contract of Transport Access Network, Ancillary Services, the Balancing Mechanism, the Balance Responsible, compensation for losses.
  • Planning, management and operation of a distribution network
    Topics covered in this course will cover the MV distribution networks: their structure and how development studies and investment decisions are carried out by the distributor ERDF, their technologies and their operating and managing rules. In that purpose, terms and concepts related to the technical and economic calculation (principle of discounting, actualized costs, benefit-cost ratio ...) will be defined and applied through practical examples. The method to elaborate master plans will also be presented. The management and operation of MV distribution networks are also explained (reconfiguration during in fault condition, SAIDI, consignment, operator roles and responsibilities). Finally, the industrial perspectives to integrate Smart Grids technologies are broached (technical and economic interest). Two labs enable to put the students in situation: R&D engineer to develop the network and operator in a context of crisis linked to a major climate event.
  • Industrial Networks
    This course aims at explaining to students the methodology of designing and sizing all the components and devices that enable the electrical distribution of an industrial network by respecting specifications and constraints (reliability, protection of equipments and people, minimizing costs) in the specifications and reliability constraints, protection of property and people at lower cost. A case studied enables to integrate current issues (renewable energy, storage and electric vehicles).
  • Electrical networks protection
    Topics covered in this course include the study of the protections of industrial and commercial installations, the detection of fault currents, the protection of persons and networks, and the integration of the protection in the command and control.
  • Labs Power networks
    These labs are designed to simulate and/or experiment various concepts seen in this unit.
    • Two labs are dedicated to take in hand the dynamic simulation software EUROSTAG that allows the study of transient slow phenomena. This software will be used to study a FACTS system (Flexible AC Transmission System) to manage voltage by compensating the reactive power in a transmission network.
    • A lab is dedicated to real-time network simulation in closed loop. It consists in testing an real protection of a distribution or industrial networks (SEPAM 2000) on a simulated network under ARENA URT. The impact of its adjustment, of the types of faults and their location will be studied.
    • A lab studies the impact of the neutral systems at the HV/MV transformer on the electrical values of the network regarding the characteristic of the fault (single phase, polyphase, resistive or not ...)

Prerequisites

  • Unit « Electrical Energy » (1st year common unit)
  • Unit « Automatic and command of systems » (1st year common unit)
  • Unit « Transformer and electrical networks » (IEE 2A)

Tests

Session 1 : ratio of the continuous evaluation CC (65%) - ration of the final individual exam CT (35%)

Session 2 : no session 2 for the CC et for the CT the mark of session 2 replace the one of session 1

The CC consists of the mean of a lab report and quizz (ENEDIS, a study of an industrial project (Scheider Electric) and a questionnaire on the RTE visits. The CT concerns the protection part.

CC 65% + CT 35%

Calendar

The course exists in the following branches:
