Electrical design method and device for 110kV transformer substation in industrial park

Abstract

The invention discloses an electrical design method and device for a 110kV transformer substation in an industrial park. The method comprises the steps of obtaining an influence factor set of the electrical design of the 110kV transformer substation, wherein the influence factor set comprises an industrial area load level, a load size, a transportation condition, a land condition, a natural condition of a site, and a short circuit level; according to the influence factor set, determining a layout scheme for construction of the 110kV transformer substation and model selection of electrical equipment, and forming a construction mode of the 110kV transformer substation; and determining an application condition and an application range of the construction mode of the 110kV transformer substation in combination with an operation and maintenance instruction of a user unit, wherein the construction mode comprises electrical wiring, equipment type selection, size and splicing mode of the electrical prefabricated cabin, and cabin body arrangement mode. The invention provides a set of design process suitable for industrial park station building, rapid station building of the industrial park can be achieved, the flexibility of land use of the industrial park transformer substation is improved, and all the modules can be flexibly arranged according to terrain conditions.

Description

technical field [0001] This application relates to the technical field of substation electrical design, in particular to the electrical design method and design device for 110kV substations in industrial parks. Background technique [0002] In recent years, with the rapid economic development, urban land use has become increasingly tight, and the scale of power grid construction has developed rapidly. The traditional 110kV substation design and construction plan has begun to show shortcomings in land use and construction period. The 110kV substation is divided into outdoor and indoor substations. The construction of substations includes structure, construction, drainage, HVAC, electrical installation, station area lighting and power, lightning protection and grounding, etc., involving "planning, site selection, survey, design, engineering, etc. Construction application, material procurement, four connections and one leveling, construction and installation construction, commi...
