Measurement-based performance analysis of wind energy systems

Wind measurements for identifying and characterizing wind resources require instrumentation and analysis techniques for defining signal processing features for gusts, turbulence, and inflow winds. This paper describes the importance of those features for determining responses of wind turbines. In addition, when the system is deployed, the instrumentation that must be coordinated to manage the utility connection requirements, such as assessing reactive power supply, fault ride-through, and power quality monitoring, is also discussed. The control schemes for wind energy generation systems are discussed and associated with the system signal processing required to control active power generation.
