摘要:
      为了解决在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的问题,本文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,并开展了现场应用。一方面,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;另一方面,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。现场应用表明,本文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:
      In order to address the issue that there is no effective method to test the functions and performances of UHVDC pro-tection system, the live-action substitution-based test scheme is proposed in the paper. Moreover, the corresponding test device is developed, and the field application is carried out. On the one hand, the various hardware interfaces of the UHVDC protection test device are employed to lively substitute the hardware environment of the tested UHVDC pro-tection system. On the other hand, the key technologies including output of digital signals with multi-protocol, syn-chronous output of multi-source signals, multi-device synchronization mechanism and replay of fault recording data are developed to ensure the lively substitution of the operational environment of tested UHVDC protection system. The field application indicates that the proposed live-action substitution-based test scheme of UHVDC protection system can effectively test the functions and performances of UHVDC protection system.
