| Distribution-grid is more complex part in power system's network, involved much fore--technique in computer communication and automation fields. The article sets about from automatic swich-core part of distribution-grid, analyzing control communication and computer part, so as to realize monitoring and controling the whole distribution-grid equipments and accomplish measuring, collecting and processing. During the period of "elevent-five", coutry lauches many instructing policies on distribution-grid building, taking Baiyun aera power-grid in GuiYang city as the case example to carry on detailed fulfillment argument, the text combine"eleventh-five" concrete request and make use of the new calculate and new craft in distribution-net control system to get direct economic performance. At the same time, distribution-grid control system concentrates the focus on the construction link of "hand in hand" swiches,expanding to computer system, communication systems and other assistances systems such as the geography information system so as to study the inside antinomy and practice meaning of the system. The judgment and grid-instauration of distributon-net breakdown is the most current technique of the control system, considering the stability of power grid and the possibility of the item, as far as possible , we will adopt more mature theories and techniques in the grid-instauration of breakdown grid in the item and put forward some new methods and new ways of thinking theoretically in dealing with power grid recovering and installation arithmetical area. By disassembling the problems of distribution-grid four sub-programs-position, insulate,recover and rebuild to realize the best choice. Strive for lengthening the life-span of the system's equipments and the balance point of the system's expanditive and encapsulative. |
