[Abstract]:With the development of social economy in China, the construction of power grid project has become an important infrastructure to ensure the development of national economy. The quality of power grid project construction directly affects the efficiency of power grid. In order to ensure the quality of power grid construction project, the national network company attaches great importance to the application of project set management and project management theory in the whole life cycle of the project. Under the premise of implementing the relevant national laws and regulations on engineering quality, a series of systems and capital construction documents have been issued to determine the primary position of quality management in the construction of power grid projects. However, because the quality management system of power network engineering project is not mature, the occurrence of quality accident is still an important problem in power grid engineering construction. This paper combines dynamic and static analysis, qualitative and quantitative analysis. By identifying the quality risk factors of power grid project construction and deeply analyzing the complex relationship between the quality risk factors, the deep causes of the quality risk are excavated. The system dynamic model of power grid project construction quality risk is built step by step, and the quality risk level of construction process is forecasted by mathematical method to guide the construction quality management of power grid engineering project. This paper fuses case analysis, literature analysis and expert investigation methods, analyzes and identifies the risk factors affecting the quality of power grid project construction, and determines the personnel, technology, management, equipment materials. The environmental five risk subsystems, combining the law of quality risk occurrence, construct the causality structure of power grid project construction quality risk, and with the help of explanation structure model analysis method. The multilevel hierarchical relationship between the quality risk factors of power grid project construction is constructed, which reveals the surface, middle and deep causes of the construction quality risk. At the same time, combined with the MICMAC method to determine the importance of various factors. The system dynamics, integrated weighting method, multiple linear regression and other methods are applied to power grid project quality risk. The simulation model of the corresponding quality risk management system is constructed, and the whole quality risk and the risk level of each subsystem are simulated by the professional software Vensimphap. From the perspective of policy design, different schemes of quality control investment ratio, input strategy and input conversion rate are worked out respectively. The effect of different control measures on system risk level in complex power grid project is observed quantitatively by comparing the change of quality risk level under different schemes. The optimization measures of quality risk management can be taken in the process of power grid project construction, which can provide support for decision makers to carry out quality risk management. To promote the establishment of a long-term mechanism of quality risk management in power grid engineering projects. In view of the above analysis results, the paper puts forward the system document as the guidance, information technology as the means, and the whole life cycle as the management process. Focusing on the guarantee measures of the Eleventh National Congress, the dynamic and linkage quality risk management mechanism of quality risk management is carried out around the "five major" quality management elements of people, technology, management, environment and equipment materials. It is expected to play a guiding role in quality risk management of power grid project construction.
