Modeling and Fault Analysis of Canal Type Small Hydro Power Plant

In this paper, the simulation model of a typical canal type small hydroelectric power plant was developed through interconnection of models of various equipments of the plant under consideration in a MATLAB/Simulink based software environment. The various components of small hydroelectric plant like governor, Semi-Kaplan turbine, synchronous generator, exciter are being considered under modeling and simulation.. The aim is to study its behavior during phase to phase fault. This study helps in verifying costs and safety conditions, in selecting the best alternatives in the early phase of design and to determine the requirements of special protection devices to control overcurrent and under-voltage.
