Abstract
The ultra high voltage direct current (UHVDC) technology plays an important role in the long-distance and large-capability transmission of renewable energy. Power grid company has to improve the reliability and efficiency of UHVDC transmission systems to support renewable energy utilization. In this paper, Six Sigma method is considered for improving the operation and maintenance (O&M) performance of UHVDC converter stations. The working tasks for the operation team and the maintenance team are introduced at first, respectively. The limitation of current O&M management is analyzed. A five-stage implementation of Six Sigma method is discussed in detail. The formed negative feedback ensures the sustainability of implementation and realizes closed-loop management. A representative equipment disposal case is used to demonstrate the adaptability and operability of the potential application of Six Sigma method.
