| The electrical power engineering has the characteristic of high investment, large scale, and complex construction procedure, involving many factors serious consequence and heavy effect. Thereby, it is necessary to implement risk identification, analysis and assessment for the construction of electrical power engineering early. The results can be reference for project decision. The paper dissects various parts of construction analysis for electrical power engineering including:risk identification, risk estimation, risk index system and risk assessment. The main contents and achievements of the paper summarized as follows:Discuss the identification method of the risk identification for electrical power engineering based on the project Work Breakdown Structure (WBS) and Risk Breakdown Structure (RBS).Base on R=P×C Model, which considers the collective effect of risk factor occurrence probability and loss serious degree, ascertain the risk level range, accordingly get the risk level of each essential factor.Establish construction risk assessment index system, and confirm relative index weight of each level with 1-9 scales method.According as the characteristic of fuzzy in risk estimation of electrical power engineering, and the risk factor is quantified by fuzzy theory. The paper put forward experience distributing method base on estimation from expert, solving the quantification issue in risk estimation. Utilizing fuzzy synthetic evaluation method, get the risk level of each index and holistic risk. Take DTP Fen run Thermoelectricity Engineering as an example; make risk analysis using textual risk model and the comparison between the two Sections.Proposed safety risk controls and disposals for thermal engineering construction. |
