Transient Behaviour of Pump as Turbine Coupled to Self-Excited Induction Generator Under Variable Load Conditions Emanuel J Nyirenda, Joseph H Kihedu, Cuthbert Z Kimambo



The transient behavior of the Pump as Turbine (PAT) coupled to Self-Excited Induction Generators (SEIGs) under variable load conditions is one of the critical aspects in small-scale hydro generation systems. This paper investigates the behavior of the PAT-SEIG system during load variations and explores the impact of transient phenomena on system performance. Simulation studies are conducted using MATLAB/SIMULINK and the effects of various loading conditions are investigated and the results are analyzed and discussed. The research findings contribute to a deeper understanding of the transient behavior of PAT-SEIG operating under variable load conditions. The study offers valuable insights for optimizing the performance and stability of PAT-SEIG system applied in small-scale stand-alone hydropower systems.
