IGCC （Integrated Gasification Combined Cycle，综合气化联合循环）电厂是未来很有前途的发电系统之一，因为它可以以一种环保的方式利用丰富的煤炭资源。与传统煤粉电厂相比，IGCC系统较为复杂，需要对其进行动力学研究，并设计合适的控制策略，以保证其稳定高效运行。本文从动力系统分析的角度对某IGCC电厂的高压空气分离装置进行了研究。EP ASU在高压塔中将低温空气分离成氧气和氮气，并将其送入气化装置和燃气轮机。利用gPROMS软件平台对低温精馏塔进行了方程建模。同时，通过动态仿真研究了系统在各种扰动作用下的瞬态特性。在动力学分析的基础上，提出了控制策略。
IGCC (Integrated Gasification Combined Cycle) power plant is one of the promising power generation systems for the future as it can utilize the plentiful resource of coal in an eco-friendly way. The IGCC system is more complicated than the conventional pulverized coal power plant, so its dynamics should be investigated and an appropriate control strategy must be devised to ensure stable and efficient operation. In this research, Elevated Pressure Air Separation Unit (EP ASU) in an IGCC power plant is studied from the viewpoint of dynamic systems analysis. EP ASU separates cryogenic air feed into oxygen and nitrogen in a high pressure column and sends them to the gasification unit and gas turbine. Equation-based modeling of the cryogenic rectification column in EP ASU has been carried out using the software platform of gPROMS. Also, the transient behavior in response to various disturbances is studied through the dynamic simulation. Based on dynamic analysis, a control strategy is suggested at the end.
