摘　　要：针对目前动态电压恢复器(DVR)的电压异常录波系统占用主控CPU核资源多,导致DVR控制器任务运行满载或超时,执行效率低的缺陷,设计一种基于双核处理器的动态电压恢复器的电压异常录波系统。分析了录波系统的双核资源分配与运行原理,详细介绍了双核录波系统资源分配与信息交互机制、电压异常检测模块、录波控制器模块等。实验部分基于双核DSP TMS320F28337D开发的DVR样机记录实际运行效果和录波波形数据,其结果证明本文提出的双核电压异常录波系统能够有效地提高DVR主控核CPU1执行效率,减少录波任务时间与资源占用,具有高效的双核交互机制以及高精度的录波数据。Aiming at the defects that the current DVR voltage anomalous recording system occupies a lot of CPU core resources, which leads to the DVR controller running full load or time out and low execution efficiency, a voltage anomalous recording system of dynamic voltage restorer based on dual core processor is designed. This paper analyzes the dual-core resource allocation and operation principle of the recording system, and introduces the resource allocation and information interaction mechanism of the dual-core recording system, the voltage anomaly detection module and the recording controller module in detail. In the experimental part, the DVR prototype developed based on dual-core DSP TMS320F28337D recorded the actual operation effect and recorded wave shape data. The results show that the proposed dual-core voltage anomaly recording system can effectively improve the execution efficiency of the CPU1 main control core of the DVR and reduce the task time and resource occupation. It has an efficient dualcore interaction mechanism and high precision recording data.
