SIMULATION OF SMALL HYDRO POWER PLANTS

Abstract

Modeling and simulation of small hydro power (SHP) plants helps in studying the dynamic response of the hydraulic systems, governor and electrical systems associated with the plant. It also helps in studying the stability of the system and the co-ordination of governor parameters with those of the hydraulic and electrical systems for optimal selection. Real Time Digital Simulator (RTDS) for SHP Plant provides a realistic simulation of hydropower plant and control centre environments. It provides efficient initial and advanced training to operators and engineering staff of different types of small hydroelectric plans, by creating training conditions very close to real operating conditions. Real time simulator based training bridges the gap between the theoretical backgrounds and required practically performed actions. A RTDS for SHP plant was developed by ALICES software is available at AHEC, IIT Roorkee. This ALICES software is utilised for present dissertation work. In this dissertation work, a simulation for Pacha SHP plant is developed and operated under various operating conditions. The various components of SHP plant like weir, channel, penstock, Francis turbine, governor, synchronous generator and exciting system for generator are considered for simulation. The simulation of SHP plant has been performed under ALICES software environment.
