Abstract Flexible HVDC system as the country 863 "Flexible HVDC access technology at the research and development of large wind farms" demonstration project, this paper describes the function and principle of the trend of the automatic control, compared with traditional dc trend reverse, let everybody form the basic concept, and in the actual operation with abnormal switch contact, communication channels, control process fluctuation drawbacks were analyzed, and put forward the increase stabilization function and improve the logical interpretation as the solution of the current conditions, although at present to solve some problems, but not from the overall situation and deal with the problem, cause for this, from a long-term perspective and put forward the improvement measures, such as the trend of the automatic control target should be flexible, by dealing with slow time delay control and smooth linkage actual trend control rationalization, introduce power grid intelligent database modification study to implementation local intelligence, Cooperates with the power grid from the macroscopic to control system oscillation and corruption problems across the cloud computing grid model of linkage mechanism, in the epilogue, especially compared with urban traffic control, points out that the soft straight system flow control is a very important and worthy of further study of the new subject, guide the relevant personnel to further study and improve the function.
