# Mini Hydro Power Plant Feasibility Study. ## Uploaded by. AI-enhanced title and description. This document outlines the conceptual framework and stages of a proposed mini hydro research project in the Philippines. It will employ a run-of-river design with small diversion dams and unregulated spillways. The project will go through preliminary and feasibility studies to investigate layout, structures, field data collection, and hydrologic studies. The goal is a 4.56 MW hydropower plant utilizing a 168 meter gross head on the Chico River tributary with minimal environmental impacts. ## Share this document. ## Footer menu. ## Support. ## Legal. ## Social. ## Get our free apps.

Students investigated the feasibility of designing, building, and installing a 4kW hydroelectric system to satisfy the need for electric power to support the research and teaching functions of Taylor Ranch, a university facility far from the utility grid. The CFWRS commissioned a student design team from Electrical Engineering to investigate, design, build, and test a small hydroelectric generating system. Diagram of Electrical System Batteries Inverter, including System Control and Protection Measurement and Datalogging Load Load Diversion Load Generator System Loads Page 4.265.2 Is construction within the capability of the design team? Important functions include generation, energy storage in batteries, inversion to 120 Volts AC, a diversion load to dissipate any energy in excess of storage capability, appropriate real-time control and protection (provided within the inverter), and data measurement and logging. The design team specified instrumentation to enable the site caretaker to quickly assess the energy storage state of the system, providing the CFWRS researchers with timely information about electric power available for their work.
