Leakage Hazard Area of Natural Gas Stations Based on Scenario Cluster Analysis
Leakage hazard area can provide the basis for decision in maintenance management and emergency evacuation of natural gas stations.However,the relevant researches were mostly focused on the single leakage scenario with the highest probability of occurrence or the most serious loss.In view of the above problems,a method based on scenario cluster analysis for the leakage hazard area classification was developed,and a gas transmission station was selected for test.The typical 153 scenarios were selected via K-means cluster analysis,and the gas distribution for different leakage scenarios were calculated from CFD simulations.Finally,a leakage classification area was obtained with the consideration of scenario probability and its gas distribution.By comparison,the leakage hazard area in this paper solved the problems of single scenario,such as bad generality and flexibility.It also improved the efficiency of work by decreasing data redundancy.
