先进控制理论在电力系统中的应用综述及展望

摘要

Since the classical control theory which was represented by Qian Xue-sen’s Engineering Cybernetics and modern control theory which was represented by the linear system and optimal control came into being in the 1950’s -1960’s, fruitful results of theoretical innovation and industrial application have been made and widely adopted in power system. In view of the numerous literatures in this research field, this paper borrows the achievements in the area of large generator excitation control during the past four decades as clues, launches a comprehensive survey and compares the classic control theory with modern control theory from respects of stability, optimality and robustness, finally reveals the intrinsic complementary between them. The modern control is the extension and development of classical control, while the classical control is the basis of modern control, so their combination is so called advanced control theory. Moreover, based on summarizing the application of advanced control theory in power system, this paper gives some outlook on the future development of advanced power system control technologies.%　　自20世纪50、60代以钱学森《工程控制论》为代表的经典控制理论和以线性系统及最优控制为代表的现代控制理论问世以来，理论创新与工业应用成果丰硕，特别在电力系统中获得了广泛的应用。鉴于该领域文献众多，主要以大型发电机组励磁控制为主线，从稳定性、最优性、鲁棒性与实用性情况等方面综合对比经典控制与现代控制理论在电力系统中的应用情况，明确指出现代控制是经典控制的发展，经典控制是现代控制的基础，二者不可分割，具有天然的互补性，为此将二者合称为先进控制理论。进一步，在总结综述经典与现代控制理论在电力系统应用状况的基础上，对未来电力系统先进控制技术的发展做了若干展望。
