Intelligent Monitoring System of Wind Power Converter Based on LabVIEW

The system was designed to achieve the real-time monitoring of the wind power converter.The sensor detected multi-channel voltage,current and temperature signals in the process of converter running,after being regulated by the conditioning circuit,the signals reached the PXI-bus data acquisition equipment,then used the LabVIEW 2009-based software platform to deal with the signal filtering,curve fitting,harmonic analysis and fault alarm.The system has been used in the development and debugging of wind power converter,it can accurately reflect the state of the converter in transient or steady state operations,and owns the characteristics of friendly interface,high accuracy,expansibility,etc.
