| 摘要: |
| 随着智能变电站大规模的投入运行，同时智能变电站扩建工作也在不断的推进。目前智能变电站改扩建技术缺乏完整的技术体系，为了界定改扩建影响范围，确保改扩建间隔配置信息不影响运行间隔信息，提出一种基于二次虚回路自动识别间隔信息的方法，将二次设备归属到间隔。同时提出一种基于间隔CRC的二次回路配置管控方法，以明确定位改扩建对母线保护装置配置信息的影响范围。最后提出基于语义识别的方法，对CCD文件二次虚回路校验，保证虚回路配置的正确性，为智能变电站改扩建提供技术支撑，提高改扩建效率。 |

| Abstract: |
| With the large-scale operation of the smart substation, the construction of the smart substation is constantly advancing. Due to the lack of a complete technical system for the smart substation expansion and expansion technology, in order to solve the scope of influence and reconstruction and ensure that the reconstruction and expansion interval does not affect the operation interval information, this paper proposes an automatic identification interval information based on the secondary virtual loop to assign the secondary device to the interval. At the same time, the secondary loop configuration management based on bay CRC is proposed, and the interval of influence on the protection of the busbar protection is clearly defined. Finally, a method based on semantic recognition is proposed to verify the secondary virtual circuit of CCD to ensure the correctness of virtual circuit configuration, provide technical support for the reconstruction and expansion of intelligent substation, and improve the efficiency of reconstruction and expansion. This work is supported by Science and Technology Project of State Grid Corporation of China (No. 521200170027). |
