Modeling and Analysis of Canal Type Small Hydro Power Plant and Performance Enhancement Using PID Controller

Abstract

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 open channel, governor and Semi - Kaplan turbine, synchronous generator, exciter are being considered under modeling and simulation. . The aim is to stu dy its behavior during transient condition. Using the simulated model enhanc ement through PID controller will be done to reduce oscillations , peak overshoot and peak undershoot during transient period and also to improve the steady state response This stud y 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.
