摘　　要：针对船舶直流幅压电网短路故障电流上升率高、幅值大的特点,对一种结合电流上升率和电流幅值的短路故障判据算法进行了研究,提出了一种基于TMS320F2812 DSP处理器平台的短路电流自动录波软件设计方案,对录波软件的工程实现方法、工作流程和通信协议设计等作了重点说明,利用脉冲功率发生器测试电路对录波软件的效能进行了测试。研究结果表明,该录波软件能够实现短路故障电流自动检测及短路全过程电流波形自动记录且实时性强,能为船舶电网事故后分析提供重要的数据。Aiming at the high-rate and large-amplitude of the short current in DC voltage-variation grid of ship,a short-fault detection algorithm with rate of current rise and amplitude of short current were researched.A design scheme of wave-recording software which is used in wave-measurement and recording of short current in DC voltage-variation grid of ship was presented.And the software should run on TMS320F2812 DSP platform.The engineering implementation method and the workflow and communication protocol of the waverecording software were highlighted.The performance of the wave-recording software was tested by using a pulsed power generator test circuit.The results indicate that the wave-recording software can realize the automatic detection of short fault current and record the whole process of current waveform.It can also provide important data for the accident analysis of ship power grid.
