摘要/Abstract

摘要：

针对给定的换热网络，应用在线控制来实现系统的持续节能，然而在换热网络运行的全生命周期内，需要考虑操作裕量和控制的自由度来保证系统的可持续性、经济性和安全性等。本文从工艺设计、控制系统设计的角度对换热网络的研究进展进行阐述分析，并在此基础上提出一种可持续节能和缓释裕量的控制方法，并利用相位轨迹求解优化的切换点以使控制变量的变化最小，实现在给定裕量的条件下合理利用裕量，进而实现系统的持续可控，并通过实例证明方法的有效性。

Abstract:

In the case of the existing heat exchanger networks, the control system is applied to operate online and save energy continuously. However considering the whole life cycle running of the heat exchanger networks, the operating margins and the control freedoms are required to ensure a sustainable, profitable and safe operation. In this paper, the research progress of heat exchanger networks was analyzed from the perspective of process design and control system design. Then, a method of margin slow-release optimization was proposed based on sustainable energy saving, which was able to realize the rational use of margin under the condition of given margin to ensure the continuous control of the system and to prove the effectiveness of the method through examples.

Key words: heat exchange networks, control system design, margin design, slow-release optimization
