Rivera Convertor Station
Rivera Convertor Station is a high voltage DC Convertor Station that transfers electricity between Uruguay and Brazil. Both countries operate at different power frequencies, therefore to transfer electricity between the two countries, it first has to be rectified to DC and then converted back to AC, using power electronic technology from ALSTOM.
The SCADA system is based on Windows NT and Panorama's Client Server technology using redundant TCP/IP Ethernet networks. The two redundant PCs at Rivera are the main SCADA Servers and form the station interface to other plant systems, via redundant communication links using protocols such as DNP3, IEC 870-5, Courier, Modbus, TCP/IP and IRIG B. They collect incoming data (timestamped accurate to 1ms resolution) and send out commands from/to the largely unmanned station. The other four PCs form remote operator interfaces and allow control and monitoring, which are located several hundred kilometres away
The system provides Control Arbitration, Real-Time Trending, Historical Trending, Alarms (to 1ms), Security and Remote Configuration facilities.
