Electrical Engineering - Networks - 4EUS3GEN

Goal(s)

The aim of the courses is

• to give to the student basics about safety and stability of Power Systems. Among others, production/consumption equilibrium and insights about stability issues related to large failures. Then basics about availability of the production units and production plan is introduced, together with energy markets issues and ability to provide ancillary services.
• power conversion of nuclear power plant is covered as well, together with the variation of output power (French REP specificity)
• Multi-tasks operating systems for critical digital control systems - protective scheme of Power Systems through a Real Time Operating System managing several tasks in parallel and application.

Content(s)

Part I "Power System and Energy Markets"
Lectures (8 + 4H)
Concerning the Power System section, a first chapter covers the structure and generalities of the large Power Systems. A second chapter gives details about the various frequency and voltage control schemes (Frequency Curtailment Reserve + Frequency Recovery Reserve both automatic and manual). A third chapter gives basics about multi-generator stability.
Concerning the Energy Market section, a first chapter present and open debate about the energetic mix in France and the consumption (forecasting, uncertainties, among others).
Tutorials (6H)
A first tutorial presents interactions between two lines. A second tutorial is dealing with two synchronous generators and their interaction in reactive power. A third tutorial is about interaction between two onload tap changers running on two parallel transformer.
Project (10H of personal work)
the project is about a bibliographic review about energy market to produce a scientific paper/ extended abstract (2 pages)

Part II "Synchronous generators and diagnosis methods"
Lectures (4H)
The aim of the part II.1 is to present the regular models of synchronous generators from steady state to dynamic (Ben Eschenburg to Park). Part II.2 is about network/generator stability from the nuclear power plant that is reduced to the generator and its transformer. Part II.3 is about the maintenance of electrical conversion parts such as generator.
Tutorials (4H)
Different tutorials will be executed, depending on the question raised and highlights.
Lecture from external engineer (EDF DTG) (4H)
The aim of this part is to present the real figures and values used for operating nuclear power plants in the generator side. This allows to present the different optimization parameters the operator can use. The lecture will be illustrated with real test case and records. A link with TSO regulations will be done as well.

Part III "Multi-tasks operating systems for critical digital control systems"
Lectures (14H)

numbers representation,
structure of a processor and external components / IOs
internal architecture evolutions (DSP, mC, IP)
priority tasks and task management
non priority tasks and task management / Synchronization and communication mechanisms.
Real time multi-tasks operating systems.

Labs (16H)

Real time operating systems over PC: task state, scheduler, synchronization, communication, mutual exclusion
Use and programming of a digital protective relays and selectivity analysis on a power System through Workbench – VxWorks

Digital electronic, Basics on Electrical Engineering
