摘要
针对飞机交流供电系统仿真中故障繁多数据流和控制流难以同时处理问题,结合双变迁Petri网和故障注入方法,提出双触发权DTPN建模方法在DTPN基础上,增加故障扰动输入和变迁状态集合,定义双变迁触发规则,给出相应的矩阵描述运行算法和共享合成规则,以描述库所状态避免网中可能存在的并发与冲突关系在建立组件BEDTPN模型基础上,根据共享合成规则建立系统整体模型仿真结果表明,模型可在实时控制汇流条输出的同时,模拟各种电源构型下驾驶舱操作和故障扰动对系统的影响。
According to the problems of various faults and difficulty to deal with both control and data flow, combined with dual transitions Petri net and fault injection method, Bi-enabling DTPN model is proposed for fault simulation of Aircraft AC Power System. The new model adds fault input and state-transition set to the classical DTPN, redefines the transition rules, and gives its relation matrix description, dynamic algorithm and sharing composition rules in order to describe the place state and avoid concurrency and conflict. After all components' models have been established, the integral model of AC Power System can be finished through sharing composition. Simulation results show that this model can achieve the real-time control of AC BUS output and simulate the impacts of fault disturbances under various power configurations.
