SCADA systems and offshore wind turbines

The article describes supervisory control and data acquisition (SCADA) as a combination of software and hardware for monitoring and controlling industrial processes. It identifies human-machine interfaces (HMIs), programmable logic controllers (PLCs) and remote terminal units (RTUs) as core components. Sensors and field devices feed data to PLCs/RTUs; HMIs present it to operators for interpretation and control.

For offshore wind, SCADA collects turbine and wind-farm information such as wind speed, rotor speed, temperature and power output, and can adjust turbine settings to balance generation and safe operation. It supports remote monitoring where offshore access is hazardous, time-consuming and costly; historical and live data can be used with condition monitoring to identify degradation and plan maintenance. The article also describes SCADA use in grid management, industrial automation and critical infrastructure.

Challenges noted include cybersecurity threats that could disrupt operations or compromise data, harsh offshore conditions affecting hardware and communications, and the need for regular software updates. Related links: Energy; Offshore wind.
