| 摘要: |
| 数字孪生作为“工业4.0”背景下的新兴研究热点，为应对新型电力系统给继电保护带来的挑战提供了关键技术支撑。为此剖析了数字孪生的内涵，并结合继电保护领域的实际应用需求，定义了继电保护数字孪生相关术语，归纳了继电保护数字孪生的期望特征。在此基础上，提出一种继电保护数字孪生系统的典型架构，并针对现有继电保护数字孪生研究在数据实时交互能力、保护逻辑透明性和接口标准化等方面的不足，指出其构建的关键技术。最后挖掘了继电保护数字孪生的潜在应用价值，预期能为后续数字孪生技术在继电保护领域的进一步研究和应用提供一定的参考。 |

| Abstract: |
| As an emerging research hotspot with the background of "Industry 4.0", digital twin provides key technical means to support the challenges to relay protection brought by the new power system. For this reason, digital twin is analyzed, and combined with the practical application requirements in the field of relay protection. The relevant terms of relay protection digital twin are defined, and its expected characteristics are summarized. A typical architecture of relay protection digital twin system is proposed. In view of the shortcomings of existing research on relay protection digital twin in terms of data real-time interaction ability, protection logic transparency, interface standardization, etc., the key technologies for its construction are noted. Finally, the potential application value of the technology is explored. It is expected to provide some reference for further research and application of digital twin technology in this field. |
