Research On The Modular Management And Economic Evaluation Of Electric Power Engineering Design

To improve the capability of power grid construction, innovating the mode of substation construction, summary, absorb the intelligent module of substation construction technology innovation and practical results, national grid of the organization of the company to complete the design of general intelligent modular substation construction, "standardized design, modular construction". Including intelligent substation modular construction technical guidelines, Smart Substation modular construction general design program, the three part of the typical construction design examples. Common in the Current State Grid Corporation of intelligent substation design based on, based on the demands of engineering and technology development, the original general design scheme of sort, merge, refinement, and optimize, the formation of national grid company level unified substation, intelligent modular substation construction general design scheme. On the basis of Q/GDW 11152 "intelligent substation modular construction technology guide", according to the characteristics of substation technology, respectively, to develop a Smart Substation modular construction general design technical guidelines. In order to guide the concrete implementation of the modular construction technology, a number of key technologies to complete a number of typical examples of construction drawings, to achieve the depth of the construction plans.Due to the State Grid Corporation of Design Department of module of construction of general design and implementation, but the application of a new technology and supporting management method and work flow or missing, this paper combined with electrical engineering modular design standards based, in a modular design to implement demand as the starting point, using the flow optimization method on the working process of the modular transformation, for the modular design of the modular management model is established. In the process of project economic evaluation after the implementation of the modular management, because of the large number of evaluation indicators, and quantitative and qualitative indicators need to be evaluated at the same time. Therefore in the technical, economic rationality, social benefit, sustainable development four aspects of the representative index evaluation using value engineering analysis, both to reduce the influence of the subjective consciousness of the people on the evaluation results, also can simplify the evaluation process.This article through economic evaluation method, design time shortened, saving the design of artificial cost cost, survey and design fees net profit rate, and ahead of schedule to complete the design, started earlier, form a huge intangible economic benefits.Modularization is the main trend of electric power design, and it is the foundation of science and technology of virtual reality technology, which is not far away from the technology of direct printing substation based on 3D technology.
