摘要
A method of optimizing the fault management system in power plants based on DD-RCM (resultchain based modeling for digital developing) and TPN (temporal Petri net) is proposed. First, the model of the fault management system was set using DD-RCM. Then, it was transformed to the temporal Petri net model by corresponding rules. Secondly, relationships among all the activities, such as choice, conflict, synchronization and concurrency, were confirmed according to the Petri net model and described employing the reengineering algorithm of incidence matrix. Thirdly, the Petri net model was reduced by combining reduction rules and conflict, synchronization relationships to optimize the fault management system in power plants. Finally, the functionality of the reduced net was proved by the temporal logic of the temporal Petri net.
基于DD-RCM和时序Petri网提出一种优化电厂故障管理系统方法.用DD-RCM方法建立电厂故障管理系统的模型,并根据对应规则将电厂故障管理系统的DD-RCM模型转化为相应的时序Petri网模型;再根据Petri网模型确定出各种活动之间的选择、冲突、同步和并发的关系.进一步用关联矩阵的重组算法对各种关系加以描述.然后用简化规则结合冲突表和同步表对Petri网模型进行简化,实现对电厂故障管理系统的优化.最后基于时序Petri网的时态逻辑证明了简化Petri网的功能性.
