"从小，父亲就教导我要学科学、学技术，出去学习后一定要回来为国家作贡献。"6月27日，中国 高校继电保护学科奠基人、天津大学教授贺家李迎来百岁寿辰。经历了近一个世纪，父亲"学科学、报 祖国"的教诲仍刻在贺家李的心中。而贺家李也用毕生实践，兑现了对父亲的承诺。 当时，短线路继电保护是世界性技术难题，国内外均无成熟解决方案。继电保护需要在几十毫秒内 准确识别高电压、强磁场环境中的故障信号，技术难度极大。贺家李带领团队日夜攻关，频繁往返于水 电站现场和实验室，笔记本上记满线路参数，在实验室模型上又开展了上百次的研究。 经过一年半的刻苦钻研，贺家李终于成功研究出一种方向纵差保护原理，并在实验室自制了"方向 纵差保护装置"，保证了狮子滩水电站按时投运发电。这一突破，填补了国内空白，并且在可靠性和灵 敏性上优于苏联研制的短线路保护装置，得到了国内外高度评价。苏联顾问风趣地称他为"能干的小伙 子"。 后来，时任天津大学电力系主任陈荫谷考虑到贺家李的卓越贡献，准备晋升他为副教授。他却婉拒 道："我还年轻，学识还不够，对年轻人还是多锻炼几年好。" 此后60余载，贺家李"敢为天下先"的创新脚步从未停歇：1964年提出首条330k ...

Core Viewpoint - The successful operation of China's first "integrated wind-solar-fire-storage" transmission project marks a significant advancement in the country's high-voltage direct current (HVDC) technology, showcasing the development of intelligent protection systems for power grids [1][4]. Group 1: Historical Context and Development - In the 1970s to 1990s, over half of the stability issues in China's power grid were attributed to relay protection defects, with high-end protective equipment being largely imported and costly [2]. - Zheng Yuping, a key figure in the development of relay protection technology, has dedicated over 40 years to advancing this field, transitioning from reliance on foreign technology to achieving self-sufficiency and innovation [2][8]. Group 2: Technological Innovations - Zheng's team developed a high-sensitivity directional protection method for high-voltage lines, leading to the creation of complete protective devices for ultra-high voltage transmission lines, generating over 5 billion yuan in value [2][3]. - The team achieved a market share of over 60% in the large-capacity generator transformer protection market, with products exported to over 20 countries [3]. Group 3: Challenges and Solutions - The complexity of modern power grids presents new challenges for traditional protection technologies, necessitating innovative solutions to ensure safety and reliability [4][5]. - Zheng's team established a differential protection technology system to address the evolving characteristics of complex grid faults, significantly enhancing fault identification and response times [4][5]. Group 4: Future Directions - With the rise of new energy systems, there is a pressing need for updated relay protection technologies to adapt to changing fault characteristics [7]. - Zheng proposed a new relay protection principle based on time-domain equivalent models, aiming to create a system that does not rely on power source characteristics, which is currently being applied in various modern energy scenarios [7].
