摘要

功率循环是最基本的热电系统之一,涉及各种工作流体和热源。这项工作为动力循环提出了一种新颖的三阶段工艺设计方法,包括性能优化、运行条件优化和结构设计。第一和第二阶段优化性能和运行条件,没有结构限制,代表理想的循环设计。第三阶段根据前几个阶段确定的最佳运行条件进行结构设计。该阶段采用了一个具有明确热力学过程的白盒模型。在这项工作中,该方法被应用于单压循环和复杂双压循环的案例研究。使用该方法,二氧化碳跨临界发电循环的净功率输出进一步提高了 5.07%。在相同热源条件下,单压和双压氨动力循环的净功率输出分别进一步提高了 51.51 % 和 61.01 %。所提出的方法可以优化动力循环的运行条件,并设计出各种运行条件下的最佳循环结构,为研究和开发可变循环结构的控制策略提供了一种新方法。此外,该方法通用性强,无需额外代码即可轻松修改热源和工作流体。这种方法避免了固定循环结构的经验选择、重复循环结构建模和性能限制。因此,这项工作为定制动力循环提供了一个快速解决方案。

A novel process design methodology for power cycle: From ideal heat matching to actual structures
The power cycle is one of the most essential thermal-to-power systems and involves various working fluids and heat sources. This work proposes a novel three-stage process design methodology for the power cycle, encompassing performance optimization, operating condition optimization, and structural design. The first and second stages optimize the performance and operating conditions without structural constraints, representing an ideal cycle design. The third stage performs the structural design based on the optimal operating conditions determined in the previous stages. This stage employs a white-box model with a well-defined thermodynamic process. In this work, the method is applied to the case studies of single-pressure cycles and complex dual-pressure cycles. The net power output of the carbon dioxide transcritical power cycle was further improved by 5.07 % using this method. The single- and dual-pressure ammonia power cycles further increase the net power output by 51.51 % and 61.01 %, respectively, under the same heat source. The proposed method can optimize the operating conditions for the power cycle and design the optimal cycle structure under various operating conditions, providing a novel approach for the research and development of control strategies for variable cycle structures. Additionally, this method is highly generalized, allowing for easy modification of heat sources and working fluids without additional codes. This methodology avoids empirical selection, repetitive cycle structure modeling, and performance limitations with fixed cycle structures. Consequently, this work provides a rapid solution for customizing power cycles.
