ROSA

Instrumentation of Stoplogs in Hydroelectric Powerplants

When inspection and maintenance is needed on hydroelectric powerplant turbines, operators need to close the water flow. This is done in different ways that depend on the type of power plant. A common method is to use stoplogs. Stoplogs are massive metallic gates that are slid in a rail that is embedded at the mouth of the turbine tunnel. The goal of ROSA is to anticipate failures in the operation of the fisher beam caused by the accumulation of sediments or organic material that may be disrupting the stacking of the stoplogs. The ROSA is an embedded electronics with sensors and sonar able to detect issues that may block the stacking.This project is funded through the P&D program of Energia Sustentável do Brasil (ESBR), regulated by the Brazilian National Agency of Electrical Energy (ANEEL).
