Control system approach to optimize the performance of off-grid micro hydro power plants
Author(s): Priyanka Malhan
Abstract: Small Hydro Power Plants are grabbing attention of many underdeveloped countries providing local power and a source of new capacity in established markets. Micro Hydro Power Plant is one among them that harnesses maximum power available in water and provides the best solution of power generation for areas like the hilly regions. Micro Hydro Power Plant has a huge potential of large amount of electricity generation out of a small water flow with minimal environmental impact. In this paper an approach is made towards the design of a control system for the Micro Hydro Power Plant which ensures optimum amount of power generation, all the time the plant runs. The intake water flow rate of Micro Hydro is controlled to generate the desired electrical power. The complete control system model is developed in MATLAB using Simulink. The transient behavior of generated active power, voltage and speed of synchronous machine are analyzed through the designed control system model.
