1. 6. Fault detection of planetary gearboxes in BLDC-motors using vibration and acoustic noise analysis

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Henrik Ahnesjö; [2020]
   Keywords : Planetary gearbox; Fault detection; Condition Monitoring; Support Vector Machine SVM ; Machine Learning; Supervised Machine Learning; Defect Pinion; Defect Planet Gear; MATLAB; LabVIEW; Soundproof-box; Noise Vibration Harshness NVH ; Gearmesh Frequency GMF ; Power Spectrum; BLDC-motor;

   Abstract : This thesis aims to use vibration and acoustic noise analysis to help a production line of a certain motor type to ensure good quality. Noise from the gearbox is sometimes present and the way it is detected is with a human listening to it. This type of error detection is subjective, and it is possible for human error to be present.

3. 7. On stochastic unit commitment for thermal power plants

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Elin Rahmqvist; [2020]
   Keywords : ;

   Abstract : Climate change is a fact, a crisis threatening every country, economy and human. Toprevent this crisis, the emission of greenhouse gases needs to decrease dramatically. 72%of global greenhouse gas emissions in 2016 came from energy production where electricityand heat account for 42% of the 72%.

4. 8. Design and performance comparison of Two-level and Multilevel Converters for HVDC Applications

   University essay from

   Author : Carlos Castillo Bonilla; Sweta Merilyn Tigga; [2019-07-03T12:44:07Z 2019-07-03T12:44:07Z 2011]
   Keywords : Elkraftteknik; Electric power engineering;

   Abstract : The purpose of this thesis is to compare a two-level and a multilevel converter for HVDC substation. For this study, both topologies were designed with different modulation strategies and compared on the basis of size, power losses and impact on power quality. READ MORE

5. 9. Methods to identify broken neutral fault in LV distribution grids by using existing smart meters infrastructure

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Christoforos Menos-Aikateriniadis; [2019]
   Keywords : ;

   Abstract : The vast majority of Swedish utility network customers for nearly a decade has been supported by Advanced Metering Management (AMM) systems, including smart meters. Vattenfall´s modern smart meters enable a new level of monitoring for LV networks and improved MV network supervision. READ MORE

6. 10. Industrial Scenario using LTE Cellular Network

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Anthony Owondo; Javad Blouchi; [2019]
   Keywords : Technology and Engineering;

   Abstract : This Thesis project used an event-based simulation tool written in MATLAB that modelled a factory scenario. Multiple base stations and a varying number of nodes were modelled. The nodes send data to the base stations and the simulation tool calculates the SINR of the received data and uses this SINR to model a probability of error. READ MORE
