Abstract:
Different with the onshore power generation equipment, marine current turbine always operates in a poor natural environment that the arrangement of measured points is restricted. With a small amount of signal, single domain usually cannot detect the fault comprehensively. A multi-domain reference method is proposed in this paper for imbalance fault detection of variable-speed direct-drive marine current turbine. The proposed method acquires the reference information from multiple domains of stator current signal for spectral analysis. First, the priority of multiple domains including time domain, time-frequency domain and angle domain are considered. Then, the feature required for fault detection is selected and reconstructed. Finally, imbalance fault detection is performed by spectral analysis. Experimental results verify the effectiveness of the proposed method in marine current turbine under complex conditions.
