SCADA Solutions Inc. (SSI) announced the development and integration of a Landis+Gyr communications system as part of its supervisory control and data acquisition (SCADA) network installed at a wind farm in the Palm Springs, Calif., area.
The Gridstream RF network from Landis+Gyr is being used to collect and distribute data between 20 NedWind 500 kW wind turbines and the central control room, which is located more than a mile away. Â
The companies say the 900 MHz Gridstream radios are installed inside the base of each steel wind tower and connected to a dedicated processor that monitors and controls the turbines through serial communication. The network includes a link to the central control room. Landis+Gyr's IP radios are used to connect to the wide area network and head end system, providing accurate network time stamps and allowing for remote access for system checks. Â
SSI and Landis+Gyr launched their research and development partnership in 2009. The application combines SSI's WindCapture SCADA software with the Landis+Gyr Gridstream RF network to deliver two-way monitoring and controlling along with data collection and reporting for wind turbine generators.
