Supervisory Control and Data Acquisition (SCADA) for a Wind Turbine Farm
Dr. Said Ahmed-Zaid
Supervisory Control and Data Acquisition (SCADA) systems are currently a standard in substations and are key to smart grid development. The goal of this project is to design a SCADA system to monitor a hypothetical wind turbine farm. The project is sponsored by Power Engineers, Inc. This design is centered around a SEL-3530 model data collector. A connections diagram is prepared to show connections to the Utility RTU (Remote Terminal Unit), the turbine RTUs, the owner's equipment, and any other equipment needed for adequate protection and monitoring. As fiber optics are used to communicate with the wind turbines, the length of these lines must meet certain signal attenuation requirements. Actual device configuration takes place after the design has met industry standards and has been approved by Power Engineers, Inc. Lab facilities at Boise State University and Power Engineers, Inc. provide SEL equipment to implement the design. Testing is done using simulation techniques to compensate for unavailable equipment and virtual line conditions. Results are displayed on a HMI (Human Machine Interface) as they would be in an Operations and Maintenance building. Success is dependent upon the tested equipment functioning correctly.
