Prediction of thermal transient in central heating network
摘要：
采用高阶精度的数值方法，建立了数值模型。以太原市城南供热系统为研究对象，对3个典型热力站由热源负荷变化引起的供、回水温度的变化进行了预测，并将预测结果与实测结果进行了比较，二者较吻合。

Abstract：
Based on the high-order numerical method, establishes a numerical model. Taking the heating system in the south of Taiyuan, Shanxi Provincial capital,as the research object, predicts the changes of supply and return water temperatures in three typical substations caused by the changing load of heat source. Comparison of the predicting result with the testing data confirms their consistency.
