摘要:
      目前,工程现场调试或运维阶段缺乏能够有效开展特高压直流保护系统功能、性能测试的技术手段。文中提出了实景替代式的特高压直流保护系统现场性能测试方案,研制了特高压直流保护系统现场测试装置。利用特高压直流保护系统现场测试装置的不同硬件接口实现被测特高压直流保护系统在物理环境上的实景替代;通过多源数据同步输出、数字量多协议输出、分布式多机同步、故障录波回放等关键技术,实现被测特高压直流保护系统在运行环境上的实景替代。现场应用结果表明,所提出的实景替代式特高压直流保护系统现场性能测试方案能够对特高压直流保护系统的功能、性能开展有效的现场测试。
Abstract:
      There is no effective method to test the functions and performances of ultra-high voltage direct current(UHVDC)protection system in debugging or operation and maintence stage of engineering field. The live-action substitution based field performance test scheme for UHVDC protection system is proposed. Moreover, the corresponding test device of UHVDC protection system is developed. The various hardware interfaces of the UHVDC protection test device are employed to lively substitute the hardware environment of the tested UHVDC protection system. The key technologies including synchronous output of multi-source signals, output of digital signals with multi-protocol, distributed multi-device synchronization and replaying of fault recording data are developed to ensure the live-action substitution of the operational environment of tested UHVDC protection system. The field application indicates that the proposed live-action substitution based test scheme for UHVDC protection system can effectively test the functions and performances for UHVDC protection system.
