About the Role
Three projects Master/Bachelor Thesis on Measurement technology applied on gas turbine
A Snapshot of Your Day
Siemens Energy, Finspång, develops and manufactures gas turbines for power generation and operation of compressors and pumps. We are a strong player in the energy transition and our gas turbines are leading the adoption of green fuels. This rapid development brings challenges also on the gas turbine measurement systems. You will be part of the group that is responsible for the design and technological progress of the measurement’s methods applied on our products.
You will apply on all three projects with one application and more details will be given under the interview process. At that stage will be very interesting to know which project is more interesting for you, but feel free to highlight that in your application too.
The projects are performed at our labs, and they can be between 20 weeks and up to 7 months long with start in April to have enough time for you to introduce developments in the test methods and collect results to validate them.
Project 1
The operation and validation of gas turbines, and the performance thereof are being monitored by thousands of sensors of various types. There are high correlations between the sensors, which opens up for a potential increase in measurement quality. Nearby sensors could give confidence to the measured value and assure good measurement quality.
The usage of machine learning algorithms for soft sensor creation has been evaluated in a previous thesis. Now, we want to take the algorithms to the next level and determine the cause of a faulty soft sensor; the underlying process or some of the ingoing physical sensors.
Project 2
One of the most exposed measurements is the dynamic pressure, monitoring the combustion process. The piezoelectric sensor should output an electric signal proportional to the pressure fluctuations, ideally without influences by the high temperature (~700°C).
All dynamic pressure sensors are tested with the in-house-designed dynamic pressure test rig. The equipment has recently been updated with a high temperature feature. This new rig will be an important tool in our strive to better understand the interference of heat variation in the pressure reading.
Next step on this journey will be to test different pressure sensors in this setup to gain knowledge of the combinatorial effects between dynamic pressure and heat radiation. Later verifications will be performed in live combustion testing. Classic signal analysis, possibly in combination with modern machine learning algorithms will be needed to understand the relations and interpret the output.
Project 3
One of the most fragile and sensitive measurement is the strain measurement. Strain gauges are installed on the surface to components that experience extreme temperatures, high pressure, vibration and thermoacoustic. The lifetime of such an installation is sometimes just a few hours. Therefore, it is very important to be sure of the correctness is the measurement chain. All signals go through a signal check before the test campaign starts. The current method for strain gauge simulation has limitations that hide some possible installation and setup flaws.
The scope of this Diploma Thesis is to design an instrument and associated method to simulate a strain gauge sensor. Connected to the strain gauge amplifier it should appear to the instrument in the same way as for a strain gauge. The strain gauge simulator should be adjustable for static and dynamic strain (resistance). Also, the amplitude and frequency of the strain should be adjustable. Having the basic function in place it is appreciated to implement features like remote control option as well as multi-channel mode.
How You’ll Make an Impact
The master thesis project is well structured, and you will have a well experienced and competent supervisor. The project plan usually follows the path where you will be responsible for:
- Literature review
- Test rig or software model preparation for testing
- Perform testing
- Analysis of test results
- Apply changes on the test rig/software model, test procedure or analysis to improve the results
- Final report/presentation writing
During the thesis you will acquire improved skills depending on the project chosen:
- Understand the concept of dynamic pressure generation and piezoelectric sensor design (Literature study)
- Perform iterative tests in the newly developed sensor test rig.
- Perform test in the atmospheric combustion rig to verify knowledge from sensor rig testing.
- Develop new analysis methods.
- Being involved in R&D-projects and prototype testing
- Contribute to a good workplace and strengthen us as a team
What You Bring
Your profile should show:
- Bachelor or master with technical profile and courses on electronics or software programming
- Labview experience
- Knowledge in measurement techniques
- Knowledge in signal analysis methods
- Curious mind
About the Team
You will be a part of a global network of highly skilled professionals. You will be able to let your competence and professional life develop within Siemens Energy’s different initiatives and opportunities. Meet interesting new people while working and developing future energy generation solutions.
The Measurement and Component Testing team is composed of highly experienced and knowledgeable test technology engineers and measurement technology engineers. We are around 20 team members, and we have for labs where we perform prototype design validation. We are part of the R&D department at Siemens Energy AB in Finspång and therefore our test measurements and methods are always evolving to meet new design validation demands and new technology developments. We are responsible for validation of both full engine prototypes as component prototyping.
Our Gas Services division offers Low-emission power generation through service and decarbonization. Zero or low emission power generation and all gas turbines under one roof, steam turbines and generators. Decarbonization opportunities through service offerings, modernization, and digitalization of the fleet.
We can offer you employment benefits such as: reduction of working hours, advance vacation, health care allowance and an eventual possibility to a flexible working place.
