  1. 1. Modeling and Analysis of PMSM with Turn-To-Turn Fault

    Författare :Joachim Härsjö; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electromagnetic forces; vibration.; inter-turn; fault; fault detection; turn-to-turn fault; Permanent magnet synchronous machine PMSM modeling;

    Sammanfattning : Thanks to its high-torque density and high efficiency, the Permanent Magnet Synchronous Machine (PMSM) is today used in a vast range of applications, spanning from automotive to wind. Since in a PMSM the excitation field is provided by a permanent magnet instead of a coil, this machine does not have a rotor circuit and thereby the risk for electrical failures can be isolated on the stator circuit.

  3. 2. Modeling of PMSM Full Power Converter Wind Turbine with Turn-To-Turn Fault

    Författare :Joachim Härsjö; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turn-to-turn; full power converter wind turbine; permanent magnet synchronous machine PMSM modeling; fault detection.; fault; Wind turbine modeling; Wind energy;

    Sammanfattning : Over the past several years the number of renewable energy installations has shown a strong increase rate. Due to the ambition to close down fossil and nuclear power plants, this rate of increase is not expected to decline during the coming decades. In particular, wind energy represents one of the most dominant renewable energy sources. LÄS MER
