  • Effects of Type and Amount of Fault Current Limiter Impedance on Stability of System after Short Cicuit Fault Occurance in Power Network 

    Modaresi, MohammadReza؛ Modaresi, Mahmoud (Islamic Azad University, South Tehran Branch, 2017-06-01)
    Due to expansion of power network, the short circuit current of power system are increased. Fault current limiters (FCL) are responsible to reduce and limit the fault currents. In addition, these components can also improve ...

  • Determine the Impedance Value of Fault Current Limiter (FCL) in Electric Power System 

    Modaresi, Mahmoud؛ lesani, hamid (Islamic Azad University, South Tehran Branch, 2017-06-01)
    In this paper, a method to compute optimum impedance of fault current limiter (FCL) is presented. The type of FCL impedance based on its resistance, inductance and capacitance has an effect on the amount of short circuit ...

  • Suppress Side Lobe Level of a Parabolic Antenna Using Disc Shaped Elements 

    Dorosti, Mohammadreza؛ Amiri, Nasrin (Islamic Azad University, South Tehran Branch, 2017-06-01)
    controlling and suppressing sidelobe level of a symmetric parabolic antenna is presented. This sidelobe suppression is done by adding three disc-shaped elements on the surface of the parabolic antenna. By adjusting the ...
