Answer to Question 1
The SCADA system can be used to start, stop, or reset wind turbine generators remotely, either individually or for groups of wind turbines in a wind farm setting. In addition, it monitors performance and helps pinpoint problem areas in individual turbines.
Answer to Question 2
Some smaller wind turbines allow the wind itself to orient the turbine into the wind. These turbines will typically have a tail fin to orient the turbine.
