Analysis of optimum performance of standalone self-excited induction generators used in distributed generation

    Research output: Contribution to conferencePaper


    The increase of public awareness toward energy crisis leads to continuous deployment of Small Scale Embedded Generation (SSEG) in the distribution network. Self-Excited Induction Generators (SEIG) represent a significant segment of potential SSEG in the market. The performance of SEIG in terms of output voltage magnitude and frequency is investigated in this paper to support the SEIG operation for different network operating conditions. The dynamic behaviour of the SEIG resulting from islanding, reconnection from/to the grid is studied in this research. The local load active and reactive power supply are the main factors that determine the SEIG performance, as they have significant influence on the voltage and frequency change after disconnection from the grid. Hence, the aim of this work is to identify the optimum combination of the reactive power supply and the active load. This is required in order to support the SEIG operation after disconnection from the grid, during islanding and reconnection to the grid. The results show the optimum range of active/reactive local load required to maintain the operation of SEIG.
