  1. 1. Permanent magnet synchronous machine using ferrite vs rare earth magnets : how do they compare?

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

    Author : Nikhil Manakshya; [2021]
    Keywords : Vehicle requirement; drive cycle; ferrite magnet; demagnetisation; environmental impact.; Fordonsbehov; körcykel; ferritmagnet; avmagnetisering; miljöpåverkan.;

    Abstract : Permanent magnet synchronous machines (PMSM are considered as viable options for automotive and traction applications. Rare earth magnets such as Neodymium Iron Boron (NdFeB is the most common choice in the PMSM for electric vehicles to achieve high power density machines. READ MORE

  3. 2. Photovoltaic Power Production and Energy Storage Systems in Low-Voltage Power Grids

    University essay from Linköpings universitet/Fordonssystem

    Author : Johan Häggblom; Jonathan Jerner; [2019]
    Keywords : electric power; power flow analysis; radial distribution system; low-voltage power grid; forward backward sweep method; photovoltaic power systems; energy storage systems; power factor; elkraft; effektflödesanalys; radiella distributionsnät; lågspänningselnät; forward backward sweep-metod; solcellsanläggningar; energilagringssystem; effektfaktor;

    Abstract : In recent years, photovoltaic (PV) power production have seen an increase and the PV power systems are often located in the distribution grids close to the consumers. Since the distributions grids rarely are designed for power production, investigation of its effects is needed. READ MORE

  4. 3. Design and comparison of PMaSynRM versus PMSM for pumping applications

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

    Author : Viktor Briggner; [2018]
    Keywords : Demagnetization; economic evaluation; permanent magnet assistance; synchronous reluctance machine; Avmagnetisering; ekonomisk utv¨ardering; permanentmagnetassistans; synkron reuktansmaskin;

    Abstract : This master thesis aimed to design a permanent magnet assisted synchronous reluctancemachine (PMaSynRM) rotor for pump applications which were to be implemented inan existing Induction Machine stator. The machine were to be compared with a similarpermanent magnet synchronous machine (PMSM) with similar torque production in termsof cost and performance. READ MORE

  5. 4. A case study on improving energy efficiency of a Granulator in the polythene recycling machine

    University essay from KTH/Energiteknik

    Author : Raveendra Sampath Kumara Sarukkali Kankanamge; [2018]
    Keywords : ;

    Abstract : The thesis focuses on the improvement/enhancement of energy efficiency of the machine; called Granu-lator of the recycling process of polythene. In the recycling process, it is observed that energy is wasted unnecessarily, and thus energy efficiency must be improved. The reason is that the granulator has been operating with an old rotor.

  6. 5. The potential of residentialdemand response to reduce lossesin an urban low-voltagedistribution grid

    University essay from KTH/Elkraftteknik

    Author : Reinout Daels; [2017]
    Keywords : demand response; smart distribution grid; power loss; DSO;

    Abstract : Demand response (DR) has been widely documented as a potential solution for severalchallenges the electrical power system is facing, such as the integration of intermittentrenewable electricity generation and maintaining system reliability undera rapid, global electrification. While l ots of r esearch has been done i nto differentmarket designs and tariffing methods, less work is available on the implications ofdemand response on power grid operation, especially for the low voltage side.
