A Comprehensive Analysis of the Fault of a Solid Insulated Tubular Bus in a Wind Farm
This paper mainly reports a case of full-field power loss caused by intermediate joint fault encountered by the solid insulated tubular bus on the main transformer low-voltage side in an actual wind farm. Through the anatomical anal-ysis of the faulty tubular busbar,combined with the action of the on-site relay protection and the inspection of the electri-cal primary equipment,the fault cause is identified. In view of the problems revealed by this fault,corresponding preven-tive measures are proposed,which may be helpful for design and selection of solid insulated tubular bus and daily operation and maintenance of new energy power plants.
