Electricity is related to millions of households, and the control and protection of the power system are crucial. Academician of the Chinese Academy of Engineering , State Grid Electric Power Research Institute Honorary President Xue Yusheng For decades, he has overcome difficulties in the direction of energy and power technology and engineering, leading team members to be at the forefront of the world in many technological breakthroughs. . When it comes to scientific research, he has always emphasized the need to look at problems comprehensively. "Human understanding is a process of gradual progress and completeness. Only by looking at problems comprehensively can we effectively solve them."
In 1978, when he heard that the age limit for the first batch of master's degree students was temporarily relaxed to 38 years old, he, who was 37 years old at the time, immediately Register for the exam. Although the review time was only one month, with his strong thirst for knowledge and solid basic knowledge, he was successfully admitted as the first master's student by the former Electric Power Automation Research Institute with the first score. From then on, he devoted himself to research and determined to become a Contribute to China's electric power research.
Over the past decades, he has achieved a large number of scientific research results. For example, the Extended Equal Area Criterion (EEAC) method invented in 1987 is still the only quantitative analysis method for power system transient stability that has been theoretically proven and implemented in engineering applications in the world. This analysis method has also been used many times in the Three Gorges of the Yangtze River Major projects such as water conservancy projects. In 2008, when a rare ice disaster in the south caused disruptive damage to the power grid, he led the team to establish a power grid risk assessment and prevention and control system for external natural disasters, and expanded the blackout defense system from within the power system to include typhoons, lightning, and mountains. External disasters such as fires and icing have upgraded the concept of power grid defense against natural disasters from "passive defense afterward" to "active defense in advance", and relevant results have been successfully applied in many provinces.
Xue Yusheng shared that power system control includes different types such as prior control, emergency control, corrective control and recovery control. On different time scales, the control processes and control measures adopted are also very different. "This requires continuous technological innovation and continuous team breakthroughs."
In his view, whether you are engaged in scientific research or dealing with scientific research challenges, understanding methods are very important. "For a complex problem, we must look at it comprehensively, break it down into small problems, and solve each problem from a coordinated perspective. Only in this way can we achieve success."
teaches by words and deeds tirelessly, and in his own words While achieving a series of achievements, Xue Yusheng is also committed to cultivating young people and inheriting and pioneering. Over the past decades, he has trained a large number of subject leaders and "scientific research leaders", guided 29 masters and 46 doctoral graduates, and 8 postdoctoral graduates. When teaching young people, he always emphasizes the need to improve one's understanding, to see parts from the whole, and to understand the whole from the parts. At the same time, you must have hard-working professionalism, excellent leadership skills, and a persistent learning mindset. "Young people must also understand that in today's society, it is difficult to solve an extremely complex problem by relying on individual efforts. It is necessary to work together through unity and joint efforts to bravely climb the peak of science and technology." (Author: New Jiangsu·China Jiangsu Net) Zhou Yongjin)
