GIS arrangement mode selection method and system based on life cycle cost

Abstract

The invention provides a GIS arrangement mode selection method and system based on life cycle cost, and relates to the field of operation and maintenance of high-voltage equipment, and the method comprises the steps: obtaining the historical operation and maintenance cost of GISs in different arrangement modes in an area where the GISs are to be arranged, and employing a regression analysis mode to obtain the historical operation and maintenance cost of the GISs in different arrangement modes; carrying out data fitting on the change curve of the operation and maintenance cost of the GIS in different arrangement modes along with the operation age limit; on the basis of the data fitting result, the operation cost of the GIS to be arranged in the whole life cycle is estimated, and the operation cost, the construction cost and the decommissioning cost form the whole life cycle cost of the GIS to be arranged; selecting a final GIS arrangement mode according to the whole life cycle cost; according to the method, the operation cost of the GIS to be arranged is estimated based on the actual operation data of the GIS in operation, the whole life cycle cost is formed by the operation cost, the construction cost and the decommissioning cost, and the most economical arrangement mode is selected according to the whole life cycle cost, so that the cost investment is effectively reduced, and the resource waste is reduced.
