超级电容车是我国新能源战略的一个重要举措.它在上海世博会上投入使用的意义重大,保障其运行安全性显得尤为重要.对于传统安全性分析方法,FTA缺乏对事故动态性的描述能力,同时在对事故定量分析方面存在局限性;ETA在对复杂系统安全性分析上亦有局限.而利用GTST-MLD模型和Petri网模型各自的优势对电容车进行安全性分析,建立GTST-MLD和Petri网模型之间的基本符号、基本类型和事故演化路径相互转化的桥梁,进而将两种方法进行集成.这样不仅对安全事故演化能给出定性描述,同时融入事故演化过程的时间等因素,给出更为准确的定量评估数据.
Super capacitor car is an important measure of our country’s new energy strategy.It is of great significance to put into use at the Shanghai World Expo to ensure its operational safety.For the traditional safety analysis method, FTA lack of ability to describe the dynamic of accidents, At the same time, there are limitations in the quantitative analysis of accidents. ETA also has some limitations in the analysis of safety of complex systems, while the safety of capacitive vehicles is analyzed by using the respective advantages of GTST-MLD model and Petri net model, and GTST-MLD and Petri net model of the basic symbols, the basic type and the evolution of the path of the evolution of the bridge between each other, and then the two methods are integrated.This not only give a qualitative description of the evolution of security incidents, while incorporating the evolution of the accident time and other factors, Give more accurate quantitative assessment data.
