Study on Optimal Efficiency of Energy Transformation Based on Network Thermodynamics

在进行以电网络方法分析能量系统时,遇到了网络结点效率的问题,它将为网络中能流与物流的输运路径提供合理方向,以达到理想的优化策略。因此提出基于网络热力学的系统最大效率表达式。以二端网络的热力学模型为例,引入参数Q,建立了R,L,H,F参数表示法下的系统最大效率通式。将该式结合kedem-katchalsky方程描述的水与溶质形成的膜输运分析中,得到膜输运网络描述的最大效率关系式,这将大大有利于膜输运的机理研究。网络热力学最大效率表达式的结构简单,通用性强,适用于热静力学及非平衡态热力学在内的复杂热力系统的分析和优化。

There is a network node efficiency problem when analyzes the energy system with a electric network method. It will be able to provide a reasonable logistics to flows of transport path to achieve the desired optimization strategy. Therefore, a maximum efficiency expression based on network thermodynamics was presented in this paper. With two-port network model of thermodynamics, for example, by introducing the parameter Q, a general formula optimal efficiency representation was established under whatever R, L, H, F parameters of the system. Applied the expression to kedem-katchalsky equations, which will be of great benefit to the membrane transport mechanism. The expression has the advantage of simple structure and high universality, and can be used for analysis and optimization whatever statics and non-equilibrium thermodynamic systems.
