Partial Discharge monitoring on cables: Physical Testing of Detection methods, Master Thesis

Publicerad 2022-10-28

Om tjänsten


Power Climate Smarter living – that's our purpose. We are looking for talented students who want to help us on our journey towards a fossil-free life. By writing a degree project at Vattenfall, you get a unique opportunity to contribute to our purpose. The only thing we ask of you is that you release your superpowers and share your energy with us.

 

About the project

Vattenfall R&D is responsible for conducting business driven technical development that creates value for the company and helps us realize our strategy. We develop cost-effective, safe & sustainable solutions to improve the infrastructure of Vattenfall assets including Hydro, Wind, Nuclear, SKB, Heat and Distribution.

Partial discharge (PD) is one of the main issues when it comes to maintenance of cables in wind farms. For this reason, gaining understanding on the phenomenon and its detection is of high relevance.

The thesis consists of conducting literature review of existing PD detection and monitoring techniques as well as testing PD detection equipment at the High Voltage laboratory at KTH. The aims are to understand the behavior of the equipment under different PD sources, to learn how to interpret the collected data and to compare different techniques in terms of performance with more conventional detection systems. The physical testing should be implemented in relation to the conducted literature review on existing PD detection methods and a summary of the available sensors in the market.

Based on the results of the analysis, we will be able to design the most appropriate PD monitoring option that would allow us to plan pro-active maintenance needed in each of our locations. In this way, we enable continued safe and stable electricity production in the wind farms in question.

 

Objective/Purpose: The ultimate goal is to gain full understanding of the potential of different PD monitoring sensors when it comes to PD.

Om oss


We at Vattenfall have decided to make it possible to live fossil-free within a generation. To succeed, we, as one of Europe's largest energy companies, must first become completely fossil-free ourselves. But that's not enough. To contribute to a fossil-free society, we must do more than just focus on sustainable energy production.

Because we are convinced that if we are to make it possible to live fossil-free within a generation, we must look at the challenge from a broader perspective than simply producing energy in a sustainable way.

Join us on the road to a fossil-free life.
