四十八岁的刘晨晖在短短两年之内,成为在国际自动控制学界公认的权威丛书中发表专著的第一个中国学者,是令人敬佩的。一九八一年九月,刘晨晖带着党和人民的重托,带着亲人的期望,离开祖国,前往瑞典皇家工学院能源研究室进修。他的导师布本柯教授,是国际著名的电力系统科学界权威。到瑞典后,布本柯教授当即交给他一项研究课题——《电力系统短期负荷预报》,同时对他说:能在两年之内完成这个研究,就算不错了。布本柯教授的决定,完全出乎刘晨晖的意料。因为出国前,领导上已为他定下了水电站自动化的研究题目。而布本柯教授出的题目,原是瑞典国家动力部委托能源研究室研究的项目。开展这个研究,要进行非常细致而艰难的数学模型分析,还得运用概率论来处理大量无规律的随机信号。不过,如果研究成功,这对祖国今后的电力建设,也很有价值。考虑到这些,他毫不犹豫地接受了这个题目。从一九八一年十月,到翌年二月,刘 In just two years, the 48-year-old Liu Chenhui became the first Chinese scholar to publish a monograph in a recognized series of authoritative books from the international academic community. It is admirable. In September 1981, Liu Chenhui, with the trust of the party and the people, left the motherland with the wishes of his loved ones and went to study at the Energy Research Laboratory of the Royal Swedish Institute of Technology. His mentor, Professor Boucoir, is an internationally renowned authority in the power system science community. After arriving in Sweden, Prof. Bubenko immediately handed him a research project, “Short-Term Load Forecasting of Power Systems,” and told him that it would be nice to complete the study within two years. Professor Bush’s decision, totally contrary to Liu Chenhui’s expectations. Because before going abroad, the leadership has set a topic for the study of hydropower automation. The issue of Professor Bubenko, was originally commissioned by the Swedish Ministry of Energy Research Department of Energy Research Project. To carry out this research, we must conduct a very detailed and difficult mathematical model analysis, we must use the theory of probability to deal with a large number of irregular random signals. However, if the research is successful, it will also be of great value to the future power construction of the motherland. With that in mind, he accepted the subject without hesitation. From October 1981 to February of the following year, Liu
