In a wind park, SCADA measures which of the following?

• A. All of the above
• B. Turbine production and availability
• C. Faults and required maintenance/repairs
• D. Component temperatures and pressures

Answer: (D)

SCADA in a wind park is about watching equipment health through sensor data. The most direct and telling signals are component temperatures and pressures. Temperature readings show how hot bearings, gears, generators, and lubrication systems are running, and they alert you to overheating, insufficient lubrication, or cooling problems. Pressure readings reveal how hydraulic and lubrication circuits, pumps, and seals are performing; abnormal pressures can indicate leaks, blockages, or degraded components. Together, these metrics provide a real-time view of the physical state of the turbines, enabling alarms and timely maintenance decisions before faults occur.

Production and availability, as well as faults and maintenance logs, are important and connected, but the core continuous measurements that drive immediate control and health monitoring are temperatures and pressures.
