| Thermal power is the oldest and the most important form of power generation.Influenced by policies such as power supply structure reform,environmental protection requirements and "double carbon" strategy,the proportion of installed thermal power capacity to installed power capacity has shown a slight decline year by year,but it still accounts for about 60% of the total installed power capacity and power generation.It is crucial to ensure stable construction of thermal power projects and avoid various risks to achieve economic and social benefits.Currently,thermal power projects are developing in the direction of high efficiency and environmental protection,with large unit capacity and construction scale,which requires a higher level of risk management than previous thermal power projects.However,the current research on thermal power project construction risk management is relatively general,and there is a lack of systematic and comprehensive research on the risks and threats faced by the construction side during the construction phase,resulting in weak risk management links for the construction side during the construction phase of thermal power projects and few systems to draw on.The systematic study of thermal power project construction risk management from the perspective of the construction side has certain theoretical value and practical significance,which is conducive to helping the construction side to improve thermal power project construction risk management.The main work of the thesis includes the following aspects: firstly,the construction risk evaluation index system of thermal power project construction from the perspective of the construction side is established.A comprehensive analysis of the factors influencing the construction risk of thermal power projects was conducted to obtain a total of five factors: environmental risk,contractual risk,economic risk,organizational risk,and technical risk,and then on this basis,17 secondary index factors were subdivided and a risk evaluation index system was established;secondly,a construction risk evaluation model based on the inverse entropy weight-AHP method for thermal power project construction from the perspective of the construction side was constructed.A risk evaluation model based on the inverse entropy weight-AHP method is adopted,combining the inverse entropy weight method,which favors objectivity,and the AHP method,which favors subjectivity,to determine the comprehensive weights.After the steps of determining the factor set,determining the evaluation set,determining the affiliation degree,determining the weight set,and synthesizing the fuzzy relationship of the risk evaluation model,the risk level is determined;finally,the validity and applicability of the model are verified by applying the empirical analysis method.Taking the construction project of boiler installation project of 2×1000MW power generation project of a power plant in Inner Mongolia of which A Power Construction Engineering Company is the construction party as an example,the constructed construction risk evaluation index system and model are applied to comprehensively evaluate the risk level of the thermal power project,and the result that the construction risk of the project is at the "medium" level is obtained.The paper then proposes targeted countermeasures in five aspects,including environmental risk,contract risk,economic risk,organizational risk and technical risk,and proposes corresponding risk monitoring measures to ensure the orderly implementation of the project.The paper systematically studies the risk management model and application of thermal power project construction from the perspective of the construction side,and the research results can provide reference for the construction side in thermal power project construction risk management and support the development of thermal power project management theory,model and its application in China.Figure [3] table [15] reference [49]... |
