Model and Simulation of Anti-delay Protection Logic Based on Finite State Machine

针对电气系统中应用广泛的反延时保护逻辑,提出了基于有限状态机原理建立此类模型的思路,建立了飞机交流电源系统过压反延时保护逻辑的有限状态机模型,利用Saber软件的State AMS模块实现了该模型,并进行了仿真测试。结果表明,建立的有限状态机模型保护值和保护时间符合设计要求,基于有限状态机原理建立反延时保护逻辑模型的方法可行。

According to the anti-delay protection logic widely used in electrical system, a kind of modeling idea based on the finite state machine （FSM） theory was given. Then the FSM model of the over voltage anti-delay protection logic of aircraft＇s AC power system was founded in Saber software StateAMS. After that, the model was simulated for test. The results show the protection value and time of the FSM mode~ meet the requirement and this kind o~ modeling method based on the FSM is viable.
