Summary

The purpose of this teaching lab is to put together all the concepts learned during the course into electrical energy by the implementation of an islanded production unit. The number of places is limited, therefore the student must contact the teacher before the beginning of the course.

Content

The goal of this teaching lab is to follow all the steps for setting-up of an islanded production unit.

 

The group consists of a direct current machine and of a synchronous machine.

 

The DC machine is used to model an hydraulic turbine. To do this, a speed control will be implemented. First a Matlab-Simscape model is devlopped and the speed control is tested in simulation, then the speed control is exported in a real time controller and tested in pratice. The whole design will be made such as, the choice of controller type, the type of control, the type of criteria ( symmetric or meplat ), measurement of small time constants, the controller implementation (C code) , and tests under steady state as well as in transient.


The synchronous machine is used as a generator and commissioning of industrial voltage regulator (Unitrol of ABB) will be made. Will also follow a customization of the coefficients of the control as well as tests in transient and steady state. The group will then be tested on different loads (resitive and capacitive loads and induction machine).
In parallel to that the voltage control will also be implemented in the simulation model to be able to compare the real world with simulations.

 

Finally, the different production units will be connected together to create an interconnected islanded network and inherent interconnection/synchronization problems will be adressed. Here as well, this will be done in simulations and then in practice.

The following will be studied, all includes simulations, pratical implementation and real tests :

  • Modeling of an hydraulic turbine by a DC machine
  • Speed control
  • Voltage regulator
  • Islanded production unit
  • Interconnection of islanded units

During this teaching lab the student is left very free and independent and learn how to sum up all the knowledged learned in different domains (control, electrical machines, grid, measurements, simulation).
