摘　　要：为有效辨识电-气综合能源系统薄弱环节,防止级联性重大事故,提出一种基于时间Petri网的电-气综合能源系统薄弱环节辨识方法。利用Petri网对系统做抽象化建模,确定故障源的关联区域子系统,并构建基于级联故障路径的时间Petri网模型,描述电-气系统故障传播的动态特性和时序差异,将级联危害评价计算融入到Petri网的运行过程中,寻找引发级联失效的关键环节,以IEEE30节点和25节点天然气系统组成的电-气耦合系统仿真分析,验证所提方法的有效性。modeling of the system,determine the associated region subsystem of the fault source,and construct the time Petri nets model based on the cascade fault path to describe the dynamic characteristics and time-sequence differences of the fault propagation of the electrical-gas system.The cascade hazard evaluation calculation is integrated into the operation of the Petri nets to find the key link to cause cascade failure.The simulation analysis of the electrical-gas coupling system composed of IEEE30 node and 25 node natural gas system verifies the effectiveness of the proposed method.
