At ABB, we help industries outrun - leaner and cleaner. Here, progress is an expectation - for you, your team, and the world. As a global market leader, we’ll give you what you need to make it happen. It won’t always be easy, growing takes grit. But at ABB, you’ll never run alone. Run what runs the world.

This Position reports to:

R&D Team Lead

Background
Electric power distribution is entering a new paradigm where power generation, loads and energy storage systems interfaced to the grid via power-electronic converters are dominating the system behaviour. This master thesis will support the development of stable and resilient microgrids through experimental investigations, specifically by studying how conventional AC fault detection methods behave in inverter-dominated microgrids.

Tasks

Read up on digital protection relays and standardised AC circuit protection functions for motors, transformers and feeders.
Install 2-3 protection relays in an existing microgrid lab setup and configure basic protection functions locally on the relays.
Evaluate fault detection behaviour experimentally for a set of baseline fault scenarios according to a test plan to be defined by the student.
Optional extensions:

Show full description

Implement a centralized protection system based on IEC-61850 protocol where the protection logic is executed on a central control unit (SSC600).
Evaluate fault detection behaviour experimentally for the centralized protection layout and compare with the local layout.
Implement and evaluate more sophisticated protection schemes, possibly including converter coordination.

Preferred background

Master student with background in Electrical Engineering, Engineering Physics, Energy Technology or similar.
Knowledge in electric power systems, specifically protection and substation automation, is beneficial.
Analytical and structured with a curious mindset.

Open-minded approach to both theoretical considerations and hands-on work in the laboratory.
