Study On Risk Management Of G Power Infrastructure Project Cost

With the rapid development of the national economy,the demand for electricity is also increasing.In order to ensure the demand-side supply,the country continues to increase the investment in the construction of power infrastructure projects,and the cost of the projects is also increasing.Due to the long construction period of G power infrastructure projects,large investment amount,complex technology and many parties involved,the cost fluctuates greatly and there are a lot of risks.This affects the investment economy of electric power infrastructure projects to a certain extent and is not conducive to the healthy,sustainable and stable development of the electric power industry.Therefore,it is necessary to study the cost risk of G power infrastructure projects,which will help improve the investment efficiency of power grid enterprises and promote regional economic development.Based on the research of related scholars at home and abroad,this paper uses risk management theory to conduct a comprehensive analysis of the cost risks in the construction process of G electric power infrastructure projects.Firstly,I should identify the risk,and expert opinions are summarized to organize the risk list.The cost risk of G power infrastructure project was taken as the primary risk and subdivided into 6 categories of secondary risks and 25 categories of tertiary risks.Subsequently,experts were invited to perform risk estimation.Through hierarchical analysis,the impact degree and occurrence probability of each type of risk were compared separately,and the respective quantitative weights were derived.Finally,the estimation results were substituted into the risk function respectively to achieve quantitative evaluation.And according to the risk index,three levels of risks,high,medium and low,are distinguished.Among them,the high level risks have design scheme selection and construction scale,which need to be focused on.Combined with the requirements of risk response,and according to the characteristics of 25 types of risks,four different countermeasures of avoidance,transfer,mitigation and acceptance are applied.Detailed countermeasures are also proposed,which can significantly reduce the cost risks.The countermeasures focusing on risks such as design plan selection,equipment price fluctuation and material price fluctuation are introduced.The design solution selection needs to adhere to the principle of preferential selection,promote BIM technology,standardize common solutions,strengthen limit management,and optimize solutions using value engineering.At the same time,design supervision should be gradually promoted in management,and design incentive policy and responsibility risk mechanism should be implemented to ensure the rationality of design scheme selection from both internal and external aspects.In the preliminary design stage of the project,for equipment and materials use the exponential smoothing method for price prediction to reduce the impact of price fluctuations on the overall cost.Finally,for each type of risk,corresponding measures are adopted and formulated in a targeted manner.
