  1. 1. Power-sourced charging over PoE to enable high power peaks

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Deshane Devis; Babak Abedpour; [2023]
    Nyckelord :;

    Sammanfattning : In contrast with well-known traditional Closed Circuit Television cam-eras, nowadays most electronic devices including Internet Protocol surveil-lance cameras , Wireless Access Point, Network Routers, Voice over Internet Protocol technologies ,and so forth are all powered throughPower over Ethernet cables. These cables are capable of delivering bothDirect Current power and data simultaneously using a single main cable for the Local area network, this tremendously assisted system integra-tors and network installers to deploy electronic devices in locations that lack electrical circuitry and eventually eliminating the extra expensesof installing additional electrical wiring as well as power supplies.

    Sammanfattning : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. LÄS MER

    Sammanfattning : Internet of Things är ett begrepp som innebär att alla tänkbara enheter kan kommunicera med varandra. Utvecklingen är snabb och antalet uppkopplade enheter ökar enormt. Detta medför bland annat att samhället blir effektivare vilket innebär både ekonomiska och miljömässiga fördelar. LÄS MER

  7. 5. A Disaggregation Model for Studying Behaviours in Power Consumption

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Ellika Wik; [2017]
    Nyckelord :;

    Sammanfattning : A feature of the Smart Grid is the utilization of flexible load in the power system. The presence of flexible load allows part of the power consumption to be shifted from peak hours to off-peak hours; this change in power consumption is called a load shift. LÄS MER
