  1. 1. Mechanical Load Identification for Spontaneous Tool Failure Monitoring

    University dissertation from Department of Production and Materials Engineering, LTH, Lund University

    Author : Jinming Zhou; Lund University.; Lunds universitet.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Material technology; Monitoring; Cutting force; Identification; Cutting; Manufacturing; materialteknik;

    Abstract : The problem of spontaneous cutting tool failure, such as tool chipping and breakage, is becoming more and more important in the manufacturing technology. The sponataneous tool failure is usually associated with the stresses subjected on the tool during a metal cutting process. READ MORE

  4. 4. Dynamic Power System Load -Estimation of Parameters from Operational Data

    University dissertation from Department of Industrial Electrical Engineering and Automation, Lund Institute of Technology

    Author : Ines Romero; Lund University.; Lunds universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; large disturbances; Load modeling; normal operation; voltage stability; dynamic load models; modeling and identification; normalization in reactive load models; Elektronik och elektroteknik; Electronics and Electrical technology; Automatiska system; robotteknik; reglerteknik; Electrical engineering; Elektroteknik;

    Abstract : The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. READ MORE

  5. 5. Dynamic Load Models for Power Systems - Estimation of Time-Varying Parameters During Normal Operation

    University dissertation from Department of Industrial Electrical Engineering and Automation, Lund Institute of Technology

    Author : Ines Romero; Lund University.; Lunds universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage stability; Load modeling; modeling and identification; dynamic load models; normalization in reactive load models;

    Abstract : Economic and environmental concerns will slow down the expansion of the transmission system in many countries. The addition of new transmission lines will be few and far between. The de-regulation of the power supply will introduce new power flow patterns on the bulk transmission systems. READ MORE
