论文摘要
我们提出了一个地区供暖系统的全面基于非线性的热功能模型，该模型由几个热量生产商，消费者和存储设备采用，该模型通过明确考虑温度动态的网状拓扑分布网络相互联系。此外，我们分析了模型的液压和热子系统表现出改变的被动性特性的条件。对于液压子系统，我们对被动性的主张利用了与DH系统的流动动力学相关的向量场的单调性，这主要将粘性摩擦效应对系统的压力进行编码。对于温度动力学，我们提出了一个基于热力学系统的屈光功能的存储功能，该功能最近用于热交换器网络的消极分析。
We propose a comprehensive nonlinear ODE-based thermo-hydraulic model of a district heating system featuring several heat producers, consumers and storage devices which are interconnected through a distribution network of meshed topology whose temperature dynamics are explicitly considered. Moreover, we analyze the conditions under which the hydraulic and thermal subsystems of the model exhibit shifted passivity properties. For the hydraulic subsystem, our claims on passivity draw on the monotonicity of the vector field associated to the DH system's flow dynamics, which mainly codifies viscous friction effects on the system's pressures. For the temperature dynamics, we propose a storage function based on the ectropy function of a thermodynamic system, recently used in the passivity analysis of heat exchanger networks.
