Research On Investment Planning Decision And Benefit Evaluation Of Power Transmission And Transformation Engineering Based On Two Dimensions

With the deepening of market-oriented reform in China's electric power industry,power grid enterprises are facing increasing pressure.How to maximize the profits and social benefits of enterprises in a gradually market-oriented competitive environment has become a major issue for power grid enterprises.In the actual construction process of power grid projects,there is often a big deviation between the completion of investment and the actual amount of investment required,resulting in unnecessary cost losses.Therefore,the study of investment plan decision-making becomes very important.It is urgent to formulate investment plan schedule that matches the construction schedule according to the actual situation of transmission and transformation projects,to do a good job in investment planning and investment plan management,to strengthen investment management and control of transmission and transformation projects,and to realize the management of the whole process of power grid investment plan,so as to ensure power grid construction projects.Maximization of economic benefits.This study relies on the historical raw data of 314 transmission and transformation projects in Jiangsu Province which have been put into operation.Firstly,the classification criteria of power transmission and transformation projects are determined,and the research objects are classified.Secondly,starting from the two dimensions of"construction time sequence" and "investment completion”of power transmission and transformation projects,the regularity of construction period and corresponding investment completion regularity of each construction stage of power transmission and transformation projects are searched.Thirdly,through the construction of investment plan decision-making model,the investment planning decision-making model is calculated,which runs through the construction of projects.Finally,from the three aspects of investment completion benefit,economic benefit and social benefit,it evaluates whether the investment plan schedule decision-making is scientific and reasonable.The main conclusions of this paper are as follows:there is a certain percentage rule in different construction stages of different types of transmission and transformation projects,the proportion of four expenditures in total investment has a certain rule,the proportion of other detailed expenditures in other total expenditures and total investment has a strong rule,and the investment completion of different construction stages of the project has a certain regularity.Through the construction of investment plan model,this paper puts forward the decision-making scheme of investment plan schedule in the whole process of construction of transmission and transformation projects,which provides investment plan schedule matching construction schedule for different types of transmission and transformation projects.According to the evaluation and analysis of investment benefit of investment plan decision-making,it is considered that investment plan decision-making has higher investment benefit,and investment plan progress decision-making has certain necessity and scientificity.
