  1. 1. Long-term Voltage Stability in Power Systems - Alleviating the Impact of Generator Current Limiters

    Author : Stefan Johansson; Chalmers University of Technology; []
    Keywords : rotor thermal overloading; dynamic load modelling; voltage stability; field current limiter; active power rescheduling; overexcitation limiter; armature current limiter; long-term power system dynamic stability;

    Abstract : The main issues in this dissertation are the behaviour of current limiters protecting synchronous generators, and the interactions that occur with other components in the power system during a voltage instability. The importance of these limiters for the voltage stability is shown both in the analysis of small models and in the simulations of larger networks. READ MORE
