  1. 1. Kalman-Filter Design and Evaluation for PMSM Rotor-Temperature Estimation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Daniel Mårtensson; [2022]
    Keywords : Technology and Engineering;

    Abstract : The permanent magnet synchronous motor, PMSM, is an efficient electrical motor that has seen a greater prevalence in the automotive industry from the increasing demand for electrical vehicles. Managing the temperature of the permanent magnet rotor is important to optimize motor utilization and avoid hardware failures. READ MORE

  3. 2. The role of location of low inertia in power systems

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Bashar Alahmad; [2021]
    Keywords : Low inertia; Frequency stability; Rotor-angle stability; Nordic 32; Kundur; PowerFactory; Small-signal stability; Inter-area oscillation; Rate of Change of Frequency.;

    Abstract : The plans to reduce the energy-related greenhouse gas emissions stimulate the deployment of electronically interfaced renewable resources. The increased penetration of such intermittent sources together with phasing conventional power plants out and the installation of High Voltage Direct Current (HVDC) links for long-distance more efficient transmission, reduces the stored inertia in any electrical grid.

  4. 3. Cooling simulation of a BEV electrical machine rotor

    University essay from KTH/Fordonsdynamik

    Author : Lisa Sparv; [2021]
    Keywords : Electrical machine; Rotor cooling; Permanent magnet; Simulation; STAR-CCM ; Elmaskin; Rotorkylning; Permanentmagnet; Simulering; STAR-CCM ;

    Abstract : The thesis work described in this report is about simulation of the cooling of an electrical machine rotor. Limitations and simplifications were made on the CAD model of the rotor with the purpose of reducing the simulation time, for it to then be used for CFD-simulations using STAR-CCM+. READ MORE

  5. 4. Online parameter estimation in electric motors

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Abizar Sadikot; [2021]
    Keywords : Technology and Engineering;

    Abstract : The permanent magnet synchronous machine (PMSM) can be used for a wide range of applications. In this case, the motor that is examined is inspired of Husqvarna's handheld electrical tools where the motor is part of its electrical chainsaw. The idea is to investigate and simulate different algorithms for online parameter estimation for the PMSM. READ MORE

  6. 5. Excitation system – simulation, tuning and evaluation

    University essay from Uppsala universitet/Elektricitetslära

    Author : Philip von Heideken; [2021]
    Keywords : ;

    Abstract : Swedish Electrical and Power Control AB (Svea Power) offers excitation systems for electrical production plants. An excitation system controls the electrical performance of the generator’s three phase outputs and must meet requirements set out in the business agency “Svenska Kraftnäts (SvK:s) föreskrifter, SvKFS 2005:2”.
