Petrobas Peru Selects FreeWave Radios To Automate SCADA Systems

摘要

Petrobas, the sixth-largest energy company in the world, is automating several SCADA applications in Peru and other countries using serial radios and Ethernet radios from FreeWave Technologies. Petrobas is employing FreeWave FGR09CSU serial radios and several HTplus Ethernet radios at compressor stations, oil collection sites, treatment plants and water ejection sites.Prior to selecting the FreeWave radios, Petrobas Peru commenced a pilot test using another brand of wireless radio. FreeWave says the goal was to have several test sites reporting to a gateway and then into a SCADA system. The challenge of the installation was to communicate to sites that were located in depressions, canyons or small streams that do not have a clear Line-of-Sight (LOS). Radios were installed at 18 different locations. Engineers at Petrobas Peru attempted to get the pilot network working for several weeks, but the radios caused large amounts of ambient noise and failed to establish reliable or consistent links.
