摘要:

高性能的光数字量校准装置有助于提高电子式互感器合并单元的可靠性和高效性。针对电子式互感器合并单元测试的通信报文处理能力和同步性两大难题，提出了基于FPGA和DSP的光数字量校准装置。分析光数字量校准装置的设计原理和技术难点，研究了基于FPGA和DSP的设计方案。重点介绍了FPGA、Blackfin DSP和人机界面三大功能模块的具体组成，进而深入研究了FPGA和Blackfin DSP的处理流程。最后将光数字量校准装置与数字化电能测试平台DRM进行联合测试，测试结果表明，基于FPGA和DSP的光数字量校准装置既能满足合并单元测试的功能性需求，又具有较好的实时性。

Abstract:

High-performance optical digital calibration device helps to improve the reliability and efficiency of electronic transformer combined unit. Aiming at the problem of communication packet processing capability and synchronization of electronic transformer merging unit test, an optical digital calibration device based on FPGA and DSP is designed. The optical digital calibration device design principles and technical difficulties are analyzed. The design scheme based on FPGA and DSP is studied. The concrete components of FPGA, Blackfin DSP and man-machine interface are introduced in detail. And then the processing flow of FPGA and Blackfin DSP is studied in depth. Finally, the optical digital calibration device and the digital power test platform DRM perform joint test. The test results show that the optical digital calibration device based on FPGA and DSP can not only meet the functional requirements of the unit test, but also has good real-time performance.
