        Abstract: The outside water-cooling system is mainly used to cool the circulating water in the converter valve, and the control structure of it is complex. The controlling logic design directly determines the working performance of the outside water-cooling system. In this paper,the controlling logic defect of the outside water-cooling system of a converter station is described, and the causes of this fault are analyzed and the solutions are proposed, providing reference for improving the operation reliability of outside water-cooling system.
        Key words: outside water-cooling system; control strategy; logic defects; preventive measures
