多源多出复杂压缩空气管网建模及能效分析

针对多源多出的复杂压缩空气管网, 通过分析管网的拓扑结构、压缩空气的压力损失规律以及压力与流量的联动特点,建立了管网矩阵模型,并基于所建数学模型,确定了管网中压缩空气压力和流量间的对应关系.能够根据管网中用气点的流量或压力波动,快速预测出管网中可能出现的压力或流量波动,为准确地用气预测提供了一种解决思路,同时为管网的能效分析奠定了基础.

Analysis on mathematical modeling for multi-source and multi-outlet complex compressed air pipe network

Array was used to build the structure mathematical model of the multi-source and multi-outlet complex compressed air pipe network. With the topology structure of the pipe network, the pressure dropping law and the linkage characteristics between the pressure and the flow of the compressed air in the pipe, the fluctuation of the pressure and flow of the air was obtained. With the model, the possible fluctuation of the pressure or the flow could be predicted rapidly, which could provide a solution for the accurate forecast of the volume of the compressed air in the network. With the accurate data of the pressure and flow, the energy efficiency of the whole pipe network can be analyzed too.
