Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng):The modern power grid is increasingly being used under operating conditions of increasing stress, for which it was not designed.
The increasing levels of variable sources such as wind and other other renewables also present stability problems.
One of these stability issues is the phenomenon of low frequency, electromechanically induced, inter-area oscillations.
Research has been carried out into the area of wide area oscillation damping to study and damp these inter-area modes.
This thesis implements oscillation damping by modulating the excitation system input of a FACTS device with a supplementary control signal generated from Phasor Measurement Unit data.
Phasor Measurement Units are becoming increasingly common and provide remote, real-time access to power system measurement data.
This thesis takes an established Phasor based oscillation damping method and combines it with modern PMU measurements to produce a hardware prototype of a real-time oscillation damping control system using remote PMU signals sent over a communications network.
The developed prototype is tested with various inputs to demonstrate the flexibility and advantages of using wide area measurements in power system control.
