U.S.-Korea Cooperative Research on the Development of Digital Computer Load-following Control Techiques for Power Plants

该提案要求资金允许伊利诺伊大学厄巴纳-香槟分校核电与电机工程教授George H. Miley博士与韩国首尔高丽大学电机工程副教授Gwi Tae Park博士进行为期24个月的研究。研究发展用于压水反应堆核电站的数字计算机控制技术的计划。针对负载跟踪控制问题，提出了一种采用自整定方法的自适应控制方法。为此，将极点分配方法与参考概念相结合，提出了一种新的自整定控制算法。将进行模拟研究，以评估该控制系统，使用一个运行工厂的模拟模型。由于燃料成本低，核电站通常在任何时候都以全功率运行，而更昂贵的核电站则运行以处理日常负荷循环。然而，核电在电力系统中的比例越大，核电机组就越有必要能够快速响应负荷变化，以平衡电网的电力负荷。在这个项目中，合作者将研究一种新的自调谐数字计算机控制方法的应用，以保持核反应堆中冷却剂的平均温度尽可能接近期望的，但在负载跟随模式下不断变化的参考值。该项目与美韩合作科学项目的目标相关，该项目旨在通过科学信息、思想、技能和技术的交流以及在互利问题上的合作，提高美韩科学家和工程师之间的合作水平。美国和韩国的合作者是在提案领域拥有丰富的研究经验和成果发表记录的备受尊敬的科学家。他们过去合作得很成功。

This proposal requests funds to permit Dr. George H. Miley, Professor of Nuclear and Electrical Engineering, University of Illinois at Urbana-Champaign, to pursue with Dr. Gwi Tae Park, Associate Professor of Electrical Engineering, Korea University, Seoul, Korea, for a period of 24 months, a program of research on the development of digital computer control techniques for use in pressurized water reactor nuclear power plants. An adaptive control technique using a self-tuning method is sought for the load-following control. A new algorithm of a self-tuning control is to be developed for this purpose by combining a pole-assignment method with a reference concept. Simulation studies will be performed to evaluate this control system using an analog mock-up of an operating plant. Because of low fuel costs, nuclear power plants usually are run at full power at all times while more expensive plants are operated to handle the daily load cycling. The larger the fraction of nuclear generation in a power system, however, the more necessary it is for the nuclear units to be able to respond quickly to load changes to balance the power load of a network. In this project, the collaborators will study the application of a new self-tuning digital computer control method for holding the average coolant temperature in nuclear reactors as close as possible to a desired but changing reference value in a load-following mode. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. The U.S. and Korean collaborators are highly respected scientists with extensive research experience and productive publication records in the field of the proposal. They have collaborated successfully in the past.
