摘要:
［目的］既有城市轨道交通40.5 kV交流综合保护装置(以下简称“交流综保装置”)依赖进口的系统级芯片，设备的国产化受到了极大限制，迫切需要进行交流综保装置软硬件的国产化开发。［方法］简述了配备系统级进口芯片的既有40.5 kV交流综保装置的结构和功能。基于我国城市轨道交通40.5 kV交流综保装置的国产化需求，提出了基于SPI(串行外设接口)总线扩展技术的双FPGA(现场可编程门阵列)国产芯片设计方案。对配备了该国产芯片的交流综保装置进行硬件电磁兼容测试、软件保护功能测试及高温高湿环境下的性能测试，并对比了国产化交流综保装置与既有交流综保装置的主要性能指标。最后简述了该国产化交流综保装置在城市轨道交通工程的应用情况。［结果及结论］该国产化交流综保装置的硬件电磁兼容测试结果及软件保护功能测试结果均满足国家电网的要求，其主要性能水平与既有交流综保装置相当。该装置在应用项目中的表现稳定可靠，性能优异。应用该装置，可有效解决部分国产器件品类不全、性能受限和接口不足等问题，可从根本上解决继电保护关键器件和软件操作系统对进口设备重度依赖的问题。
Abstracts:
［Objective］ The existing 40.5 kV AC comprehensive protection device of urban rail transit (hereinafter referred to as AC CPD) relies on imported system-level chips, which greatly restrict the localization of equipment, so it is urgent to localize the software and hardware development of AC CPD. ［Method］ The structure and function of the existing 40.5 kV AC CPD equipped with system-level imported chips are briefly described. Based on the localization requirements of 40.5 kV AC CPD in China′s urban rail transit, a domestic chip design scheme with dual FPGA (field programmable gate array) integration based on SPI (serial peripheral interface) bus expansion technology is proposed. The hardware electromagnetic compatibility test, software protection function test, and performance test in high temperature and high humidity environment are carried out on the localized AC CPD equipped with domestic chips, and the main performance indicators of the localized and the existing AC CPD are compared. Finally, the application of the localized AC CPD adopted in urban rail transit engineering is briefly described. ［Result & Conclusion］ The test results of hardware electromagnetic compatibility and software protection function for the localized AC CPD meet the requirements of the State Grid, and its main performance level is equivalent to that of the existing AC CPD. The device is stable and reliable in the application project, and the performance is excellent. The application of this device can effectively solve the problems of incomplete categories, limited performance, and insufficient interface of some domestic devices, and fundamentally solve the problem of relay protection key components and software operating systems heavily dependent on imported equipment.
