总能系统理论研究进展与展望

The Development and Prospect of Total Energy System

我国著名的科学家吴仲华教授倡导能的梯级利用与总能系统已有20多个年头,在这期间世界能源动力系统开拓发展正是沿着这个思路蓬勃展开。从总能系统理论的发展历程出发,概述了近年来总能系统理论研究所取得的重大突破,包括从物理能的梯级利用到化学能的梯级利用范畴的拓展,进而演变为能的综合梯级利用原理;以能的品位变化规律分析为核心的总能系统理论分析方法的开拓;基于总能系统集成理论的化工-动力耦合等新型系统集成思路以及相应的能源系统集成创新等。总能系统已成为当代能源科学的一个分支和发展主流,它对科学用能和经济社会可持续发展都有重大影响。

It has been more than twenty years since the energy cascading utilization principle and the concept of total energy system were proposed by professor WU Zhonghua. Thanks to this guidance the innovations of the energy and power system have made a great advancement. The recent progresses and breakthroughs in the theory of total energy system are reviewed in this paper, including the expansion of energy utilization from the field of physical energy to the field of chemical energy and further the combined cascade utilization of physical and chemical energy; the methodology of total energy system analysis based the energy level change of related processes; the thoughts and innovations of system integration such as system of coupling chemical production and power. Total energy system has been an important branch of energy science and makes more and more contribution to the sustainable development of scientific energy utilization, economy and society.
