A large renewable energy production company needed a solution for connecting multiple sensors to an Ethernet based SCADA system, ,allowing remote monitoring and management of a river based hydro scheme.
The renewable energy system consists of a series of horizontal axis turbines which use tidal and river currents to generate energy without restricting the natural flow of water.
Sensors are installed directly in the water near the turbines to measure turbulence, temperature, strain and humidity, as well as to detect leaks and ultimately determine the efficiency and performace of the system. These sensors then input data to a SCADA system, which analyses and monitors system conditions.
The DeviceMaster RTS-4 is installed directly into the SCADA interface box and allows serial communication between the SCADA computer system and the multiple sensors. The sensors communicate through multiple serial protocols (RS-232, RS-422, RS-485).
The DeviceMaster RTS-16 is mounted along with multiple servers and electrical grid interfaces in the control room, which is about 10 metres from the water.
An Ethernet connection between the DeviceMaster and the system server eliminates the need for extensive serial cabling, reducig the cost and complexity of the overall SCADA system. The DeviceMaster’s rugged housings, wide temperature rating and port configuration provided this energy production system with the stability and flexibility required.
