中文摘要：

为满足控制策略研究的需要,提出了一种母管制并列运行机组的分布式建模方法。首先将母管划分为若干由源/汇、管段组成的基本单元;再为每一基本单元建立零静差近似分布解耦传递函数矩阵模型;最后对相邻基本单元光滑连接,构成整体仿真模型。其零静差管路分布模型和光滑联接算法分别提高了模型仿真的稳态和动态精度。基本单元进一步扩展为组合单元,实现大母管系统的分层建模。该建模方法广泛适用于由源、汇和蒸汽传输母管组成的总线型多源/汇网络。仿真实验结果验证了其有效性。

英文摘要：

For supporting the study on control strategy, a method for modeling the approximate distributed parameter object of the main-pipeline control system was advanced. Firstly, a principle was established to plot out the main-pipeline into some basic cells containing the fountain/conflux and the pipe section. Secondly, a near distributed decoupling transfer function matrix model without steady error was built for each basic cell. Finally, a smooth arithmetic was adopted to joint all the conterminous cells into a whole system model. The pipeline model with zero steady error and smoothly-connecting arithmetic can improve the steady and dynamic simulating precision of model respectively. The basic cell can be configured into more complex combinations further for easily modeling the larger main-pipeline system by delamination. The method also has a widely applied scope of modeling all the bus networks composed of the fountains, confluxes and the steam-transportingpipelines. Some simulated experiments with favorable results prove the validity of the modeling method.
