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,满足机务维护模拟机对系统操作和故障仿真的要求
In order to solve the problem that it is difficult to deal with a large number of data flow and control flow in the AC power supply system simulation, a dual triggering DTPN modeling method based on DTPN is proposed to increase the disturbance input and transition state set , Define the rules of double-change triggering, and give the corresponding matrix description and running algorithms and shared composition rules to describe the state of the place to avoid possible concurrency and conflict in the network. Based on the component BEDTPN model, set up the system as a whole according to the shared composition rules The simulation results show that the model can simulate the impact of cockpit operation and disturbance disturbance on the system under various power configurations while controlling the output of the bus bar in real time to meet the requirements of maintenance and maintenance simulator for system operation and fault simulation
