Fault-Ride-Through Measurements and Model Validation of the Siemens Wind Power D3 Variable-speed Direct-drive Wind Turbine Platform.

the rapidly increasing share of wind power in the electrical power system is both concerning and challenging for the system operators. This leads to stringent requirements for the connection and operation of Wind Power Plants (WPPs) and respectively Wind Turbines (WTs). Taking these and other challenges into account, the Siemens Wind Power (SWP) 3.X MW variable-speed direct-drive WT series or D3 platform (SWT-3.0 MW, SWT-3.2 MW and SWT-3.4 MW) employ direct-drive technology that reduces the components' wear and tear; thus improving performance, reliability and maintainability. Furthermore, for the very purpose of grid assessment and system studies, SWP has developed and provides dynamic electrical simulation models for the D3 platform in various power system simulation tools, such as DIgSILENT PowerFactory, Siemens PTI PSS®E, PSCAD, EMTP-RV and PSS®NETOMAC. The dynamic simulation models are validated against fault-ride through tests and other specific purpose measurements in order to ensure accurate model performance. This paper presents measurements and model validations of SWT-3.2 MW WT. Measurement results are scalable and the results and performance can be easily extended to other Wind Turbines of the D3 platform including SWT-3.0 MW and SWT-3.4 MW as they all share a common converter hardware and software core. The presented results as well as other benchmarking results show relatively good match between measured and simulated results. [ABSTRACT FROM AUTHOR]
