The hydrogen production station system is complex and vulnerable to external attacks,causing cascading failures and serious safety accidents.The cascading failure deduction method based on event tree was adopted to determine the consequences and occurrence probability of cascading failures of hydrogen production station equipment.On this basis,a cascading fault risk evaluation index system considering safety,economy and environmental protection was established.Considering the randomness and uncertainty of serious consequences and impact,a fuzzy membership function was used to quantify the evaluation index.Finally,a risk assessment model based on evidential reasoning was established and applied to the risk evaluation of hydrogen production station equipment,to realize the risk assessment and ranking of hydrogen production station equipment.The example shows that the method is feasible and effective,which provides a support for the next step of making safety precautions for hydrogen production station equipment.
