  1. 1. Machine Learning for Predictive Maintenance on Wind Turbines : Using SCADA Data and the Apache Hadoop Ecosystem

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :John Eriksson; [2020]
    Nyckelord :Predictive maintenance; machine learning; hadoop; spark; mllib; apache; wind turbine; wind turbines; stacking; bagging; multilayer perceptron; decision tree; random forest;

    Sammanfattning : This thesis explores how to implement a predictive maintenance system for wind turbines in Apache Spark using SCADA data. How to balance and scale the data set is evaluated, together with the effects of applying the algorithms available in Spark mllib to the given problem. LÄS MER

  2. 2. Vibration analysis for predictive maintenance of a rotary pump. : Optimal accelerometer configuration based on vibration analysis for cavitation detection of a bi-winged positive displacement pump.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Gustav Osswald; [2019]
    Nyckelord :;

    Sammanfattning : Predictive maintenance based on condition monitoring uses sensor and system data to prevent damage, in advance to a failure occurring, allowing for a service to be performed at an optimal position in time. Condition based predictive maintenance estimates time of system failure based on a priori information, which has shown to be much more cost effective than traditional maintenance methods. LÄS MER

  3. 3. Survival Analysis using Deep Learning for Predictive Aging Models of Batteries in Electric Vehicles

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Ganesh Chaitanya Kudaka; [2019]
    Nyckelord :;

    Sammanfattning : With the growing EV market, predictive maintenance of batteries is one of the key challenges faced by the car industry. Since this technology is still nascent, most of the battery data obtained is through simulations which may not give an accurate estimate of the battery behavior in the real world. LÄS MER

  4. 4. Predictive Maintenance and Data Analysis in Ellevio's Distribution Grid

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Joshua Odekvist; Robert Antar; [2019]
    Nyckelord :;

    Sammanfattning : As part of the international EU project Integrid, Ellevio has started a pilot project where measurement equipment has been installed in secondary substations in Stockholm Royal Seaport. The purpose of the pilot project is to improve operation, maintenance and future planning of the grid. LÄS MER

  5. 5. Vibration analysis for condition monitoring of mechanical presses

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Julia Runesson; [2019]
    Nyckelord :Vibration analysis; Predictive maintenance; Condition monitoring; Mechanical press; Press maintenance; PSD; DFT FFT; RMS; Kurtosis; Technology and Engineering;

    Sammanfattning : In a world where the concept of just-in-time has been lifted outside of the manu-facturing world and onto the market, the increasing demand of luxury wares like cars is accompanied only by tougher industrial conditions and no room for error. Loss of productivity and decrease in efficiency can be devastating to any manufac-turing company in today’s market climate. LÄS MER
