摘要
提出了一种机载配电系统过流保护算法,该算法综合考虑了国际电工委员会标准IEC 255-3规定的反时限过流保护要求及相应的返回特性要求,具有明确的物理意义,反映了过流保护及返回时的负载热效应,可以实现对配电系统更为合理的过流保护。还建立了算法的有限状态机模型,并基于FPGA实现了该算法,静态测试及动态测试实验结果验证了该方法的可行性。
A solution of aircraft power distribution protection was introduced, which considered the international electro-technical commission standard IEC 255-3 inverse-time trip and reset characteristic comprehensively, it has a clear physical suggestion, meant to coordinate the over-current heat characteristic of electrical loads, and protect the distribution system more appropriately. A Finite State Machine model of the solution was built and implemented based on FPGA. A series of static and dynamic test experiments and their precise results indicate the valuable quality of the solution.
