PPT|人工智能在继电保护领域的研究与应用
本文由中国电科院杨国生撰写，聚焦AI在新型电力系统继电保护中的技术落地与研究方向，系统阐述技术背景、核心应用与未来展望。
01
研究背景
  1. AI发展阶段历经推理期、知识期、统计学习、神经网络与大模型四阶段；当前基于Transformer的大模型在多模态、复杂推理上取得突破，成为技术主线。
  2. 新型电力系统痛点新能源占比提升带来转动惯量下降、故障特征复杂、高阻/间歇性故障辨识难，传统机理型保护适应性不足。
  3. AI赋能价值
AI用于电网仿真、优化调度、新能源预测、继电保护分析，是保障电网安全稳定的关键技术路径。
02
核心研究方向
  1. 数据智能融合与自生长核查多源异构数据（电气量、设备状态、环境）一体化治理，实现保护数据自动校验、异常识别与闭环修正，提升数据可靠性。
  2. 大模型+知识图谱增强的缺陷诊断用大模型做波形/文本/图像多模态理解，结合电力知识图谱做故障定位、缺陷分类与根因分析，提升复杂故障诊断准确率。
  3. 数据与机理双驱动的故障原因智能辨识
融合传统物理模型与AI数据驱动，兼顾确定性与泛化能力，解决高阻接地、新能源扰动等难判故障，实现快速、精准、可靠动作。
03
工作展望
面向新型电力系统，持续推进数据-算法-模型-工程一体化落地，强化大模型与继电保护深度融合，构建自适应、自学习、自恢复的智能保护体系，支撑电网安全高效运行。
核心结论
AI已从辅助工具升级为继电保护核心使能技术，通过数据治理、大模型诊断、数据+机理融合，破解新型电网保护难题，筑牢电网安全防线。
