The Risk Assessment Research About Power Plants

With the growing demand for electricity in china, many power plants are established all over the country. At the same time, many accidents associated with the production of electricity happened. The accidents in electricity production impact on people's production and life directly. How to keep the electricity production process safe has become an important factor to social harmony, stability and unity. So, the effectively risk assessment for power plants and realizing the hazard and potential trouble exist in the electricity production process has become an important part to keep the normal social development.After the detailed analysis about the production process of power plants, the author chose the hybrid method of four methods as the main risk assessment method to assess a power plant. The four methods are Safety Check List, Preliminary Hazard Analysis, Fault Tree Analysis and Simulation Analysis of the consequences of accidents. The hybrid method make up the limitation of each one used, it is very scientific and useful that analysis and evaluation from both global and local. The author take the reality that the system is complex, the process is boring and workers always missing some work projects or mistaking some projects into account, he developed the software named the auxiliary system of the risk assessment for power plants. The software is very strong in flexibility. According to the actual situation, workers can add or delete some function. The software made the process of risk assessment procedures, reduced the intensity of labor and improved the accuracy and efficiency of risk assessment. At the same time, the author added the computer auxiliary analysis of three-dimensional into the method of the simulation analysis of the consequences of the accident. The computer auxiliary analysis of three-dimensional use current popular 3D technology established the Virtual power plants. It is good at the enterprise safety management, accident analysis and the simulation analysis of the consequences of the accident. On the other hand, the author hang the auxiliary system of the risk assessment for power plants and the computer auxiliary analysis of three-dimensional together, It can help workers getting data in the process of risk assessment. Users can use the results witch 3D simulation analysis system given.The author bring 3D technology into the process of risk assessment, using the technology of virtual reality and the computer assisted procedures, the risk assessment can be finished under the circumstances of visualization and procedures, it is important to improve the quality and efficiency of the risk assessment.
