Study on Reducing Failure Rate of DC-DC Modules in Wind Farm Units
Reducing the failure rate of DC-DC modules in wind farm units is a complex and challenging topic.This paper first provides an overview of functions,utility,composition,and working principle of DC-DC module of wind farm units. It then studies and categorizes the types of failure faults of DC-DC module,and establishes an online collection and analy-sis system specific for abnormal information of wind farm unit DC-DC modules.It finally innovatively proposes a data-driven fault handling process and a knowledge-based fault handling process for the DC-DC modules,both of which not only ensure the accuracy of fault handling,but also improve fault handling efficiency,reduce unit downtime,and achieve re-duced failure rates and improved production efficiency.
