1. 16. Mitigating SSCI in a hybrid wind and PV farm utilizing PV-STATCOM : A Swedish case study

   University essay from Högskolan Dalarna/Institutionen för information och teknik

   Author : Isabelle Löfgren; [2022]
   Keywords : impedance analysis; PV-STATCOM; SSCI; SSO; SSR; sub-synchronous control interaction;

   Abstract : The share of electricity generation in the power system being based on power electronics is increasing, which will impact the system in different ways, such as an increased risk for undesired interactions. An example is doubly fed induction generator (DFIG) based windfarms which have been shown to present negative resistance in (parts of) the sub-synchronous range (i. READ MORE

3. 17. NVH analysis and optimization of electric powertrain

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Anujit Dafle; [2022]
   Keywords : Electric powertrain; Gear whine; Noise Vibration Harshness NVH ; Elektrisk drivlina; kuggvin; buller och vibrationer;

   Abstract : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. READ MORE

4. 18. Structural Dynamics at Higher Frequencies using the Finite Element Method : Assessment of Solver Algorithms and Component Mode Synthesis for Dynamic Response Analysis of Large Structures

   University essay from KTH/Hållfasthetslära

   Author : Khashaiar Noushin; [2022]
   Keywords : ;

   Abstract : Scania is making a transition from traditional combustion engines to electric vehicles and therefore developing methodology for high frequency analysis of large structures. The computational time size of results files are impractically high, making any analysis infeasible. READ MORE

6. 20. Estimation of Input Forces on a Cutting Tool using Strain Output Signals

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Ram Pradip Mahato; Jiacheng Ma; [2022]
   Keywords : Lathe tool; Multiple sensor signals; Modal analysis; Input force calculation; embedded sensor force; MATLAB;

   Abstract : Lathes are frequently used in industrial production. It is an important parameter to calculate the force exerted by the cutter head on the raw material. Knowing the force acting on the cutting tool will aid in predicting the displacement of the cutting edge as well as predict displacement of the workpiece. READ MORE
