[Abstract]:This paper mainly introduces the principle of key primary equipment of intelligent substation, with emphasis on the intelligent configuration scheme and debugging technology of intelligent substation. Intelligent substation, divided into process layer (equipment layer), interval layer, station control layer. The process layer (device layer) includes intelligent devices composed of primary devices and intelligent components, merging units and intelligent terminals to complete substation power distribution, transformation, transmission and its measurement, control, protection, metering, condition monitoring and other related functions. Intelligent primary equipment mainly includes intelligent transformer, intelligent high voltage switchgear, electronic transformer and so on. The definition and technical principle of intelligent component, intelligent terminal and merging unit of intelligent primary device are also described in this paper. Based on the construction of Changli 500kV intelligent substation, the first 500kV intelligent substation of Jibei Electric Power Co., Ltd., this paper determines the final intelligent configuration scheme of Changli station by analyzing and comparing the main realization methods of intelligent switching equipment and transformer. In the aspect of switchgear, all kinds of intelligent monitoring devices are equipped with a set of intelligent system units through functional integration, and the main transformer is composed of equipment body and intelligent integrated components. Based on the in-depth analysis of the key technology of primary equipment and intelligent configuration scheme of intelligent substation, combined with the debugging work of Changli Station, the debugging technology of intelligent substation is studied. The debugging work of intelligent substation is very different from that of conventional substation. The integrated test is added between the factory test and the field debugging of the intelligent substation, and the overall debugging efficiency is improved. In the debugging work, the problems encountered are deeply analyzed and the corresponding solutions are worked out to further guide the debugging of intelligent substations in the future.
