  1. 1. Identifying Power Quality Issues in LV Distribution Grid by Using Data from Smart Meters : Exploring possibilities of machine learning algorithms

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

    Author : Samantha Chen; [2020]
    Keywords : ;

    Abstract : Since there is a significant potential to supervise the low voltage network with the assistance of the end-customer smart meters, Vattenfall Eldistribution AB wants to take advantage of such data. Therefore, this project’s overall goal is to investigate how some specific grid disturbances could be detected in certain meter data types. READ MORE

  2. 2. Non-Invasive Liquid Metering Method Analysis

    University essay from KTH/Mekatronik

    Author : Gustav Sten; Thibault Helle; [2018]
    Keywords : ultrasonic; liquid; metering; non-invasive; ultraljud; flöde; vätska; icke-invasiv;

    Abstract : The ability to measure flow in pipes often introduces expensive and difficult installations due to existing flow-meters being invasive. To solve this a non-invasive solution has been found by testing and evaluating different mechanical and electrical methods using ultrasonic piezo-crystals and time-of-flight calculations. READ MORE

  3. 3. Current Ripple Simulation in DC Traction Voltage System of an Electric Bus: 2

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Filip Gard; Linda Nilsson; [2017]
    Keywords : Current Ripple; LTSpice; Simulation; Measurement; Volvo; Electric vehicle; Electric bus; Technology and Engineering;

    Abstract : Current ripple can cause a lot of problems as it spreads in the DC-side of the TVS of electric and electric hybrid vehicles. Fully knowing the properties of the TVS can be used to build a simulation model to determine the spreading of current ripple beforehand, which in turn is useful for calculating component placement, optimal filter sizes, and component lifetime.
