DSP involvement in Power Systems (help need for Master thesis)

Click For Summary

Discussion Overview

The discussion revolves around finding a suitable topic for a Master's thesis that combines digital signal processing (DSP) with power systems. Participants explore various aspects of power systems, including AC power distribution and variable-frequency drives (VFDs), while considering the implementation of ideas on FPGA boards.

Discussion Character

  • Exploratory, Homework-related, Technical explanation

Main Points Raised

  • One participant seeks suggestions for a Master's thesis topic that integrates DSP with power systems.
  • Clarification is requested regarding the type of power systems, with a preference expressed for AC power distribution systems over VFDs.
  • Another participant suggests exploring sub-synchronous resonance and power system stability, referencing past experiences with turbine shaft torsion and analog measurement methods.
  • There is a discussion about the definition of VFDs, with participants confirming that they relate to variable-frequency drives used in brushless motors.
  • A participant expresses interest in implementing a digital phase converter on an FPGA board.

Areas of Agreement / Disagreement

Participants generally agree on the interest in combining DSP with power systems, but multiple competing views remain regarding specific topics and approaches, such as the focus on AC power distribution versus VFDs.

Contextual Notes

Some limitations include the lack of specific details on the desired outcomes of the thesis and the varying levels of familiarity with technical terms like VFDs and DSP applications in power systems.

Who May Find This Useful

Students or researchers interested in the intersection of digital signal processing and power systems, particularly those considering thesis topics or FPGA implementations.

Hello.

i am searching for a topic for my Master Thesis. My Master is on Power Systems and i want to combine my thesis with digital signal processing. but i am stuck on finding a topic.
So if anybody can helping choosing a subject or giving me some ideas that i can work on?


Best regards

What kind of power systems? Do you mean like AC power distribution systems (like the Smart Grid)? Or do you mean VFDs and other high-power electro-mechanical systems?

I would prefer AC power distribution system... But if you got any ideas on VFD I am happy to hear them...
 
I think of DSP hardware as faster than necessary for power system control. But the math is all the same...

Try a search on terms
SSR (sub synchronous resonance)
power system stabilityi did once have opportunity to look into turbine shaft torsion because resonance was suspected.
We built an analog meter to measure and record it. Nowadays they do that with PC's.

One wonders whether clues might be present in armature current signature...

Fascinating times we live in.

what'sa VFD?
 
okay, for them brushless motors, right?
 
i am looking for something that will be possible to implement on a FPGA board.
does a Digital phase converter can be design on an FPGA board
