Risk Management Of Power Grid Project Based On Total Life Cycle Theory

Risk management has a great influence on the power grid projects. As a basic industry, power grid industry has great relations with national energy security, social public security, and society and economy development. How to identify the risk factors, evaluate the risk factors and make solutions to the risk factors are the keys to power grid enterprises and projects risk managementBased on total life cycle and risk management theories, considering with the characteristics of power grid engineering, this paper analyzed the study results and conclusions of engineering and project risks at home and abroad. Specific analyses were used into risk definition, risk causing reasons, risk classification and risk types. Comparisons between methods of risk definition and risk evaluation were employed to choose the proper method. The identifying list and improved LEC method and the ISM model were selected to build the risk management system. Relying on these methods and considering with an empirical case of 220kV transmission and transformation project, the risk factors in different engineering construction stages were identified. Meanwhile, the risk levels and risk degrees were determined. The ISM model was used to analyze the transmission mechanism between risk factors. The results found that two risk transmission chains i.e. construction and cost, are important to risk management of power grid project. At last, the risk management of power grid project was built from the aspects of organization, basic solution and specific solutions. The research can provide references and advises for risk management of power grid project and promote the implementation of the related works.
