Smart Grid Substation Based On The Theory Of The Whole Life Cycle Cost Management Research

With the development of social economy,problem of energy shortage becomes serious day by day,with the structural contradictions more and more prominent.It is necessary to push on the smart power grids of which UHV power network acts as the backbone network and to generalize “Internet of the global energy” in the world with the guidance of national policy,to address these challenges.As a pioneer,the construction of smart substation transforms from a regular station and digital station to a real smart station.Where is the advantage of smart substation over regular station? What is the impact of increased investment on the whole life cycle? On the surface,the smart substation costs much more than normal substation which is highly integrated and rapidly responsive at the technical level.In the bidding stage,from the cost management point of view,smart grid can be understood as in the normal substation based on the addition of some smart devices.How to correctly view and calculate the smart devices in the bidding stage of smart substation investment in the impact of investment in the latter stage of the impact of investment,and the impact of the latter stage of the investment is greater than the previous stage of the investment funds and other issues worth thinking about.As a result,it is with important significance to analyze and study the comparison between investment of intelligent substation and conventional substation by introducing the whole life cycle cost management theory and the analysis of the research of intelligent substations.With the smart substation as the research object,this article firstly expounds the concept and basic theory of whole life cycle cost management comparing with the current popular whole process project cost management,demonstrates the advantages of the application of the whole life cycle cost management in electric power engineering construction project,and provides the whole life cycle cost management in electric power engineering construction project with theory basis;Secondly,it carries out the research on all kinds of expenses which constitute the smart substation whole-life LCC,demonstrates the feasibility and necessity of application of theory of whole life cycle cost management in electric power engineering construction project and establishes LCC model of smart substation;Thirdly,it carries out the LCC controlling and research on all stages through the analysis of LCC construction expenses at decision-making stage,design stage,bidding stage,construction stage and operation and maintenance stage of the smart substation;At last,the article takes a 330 kV substation project in Ningxia as an example,to compare the LCC of smart substation with normal substation using LCC model,providing with the same scales,construction conditions and programs based on theory of the whole life cycle;and the article predicts the “13th Five” cost trends of smart substation,based on the construction cost of the intelligence substation that has been already completed within Ningxia electric power company business scope during “12th Five” period,research and demonstration of investment costs IC investment costs of the various trends.The article analyzes the development prospect of the smart substation and demonstrates that the cost of investment on smart substation during the whole life is less than that on conventional substation in future,through the theory research of the whole life cycle cost management at home and abroad with theory and actual case combined.Based on the actual situation of cost management of electric power engineering construction project in Ningxia Electric Power Company,this article emphasizes the practicality and effectiveness in order to provide some reference for the cost management of electric power construction project.
