The load variation for actual network operation can be expressed by rigid theory of the unsteady state condition. The unsteady state condition model of water distribution network is founded based on the new model with the inertia node imported.
实际管网正常运行时单纯的负荷变动可以抽象成基于刚性理论的非稳态进行研究,在引入惯性水头项后,建立了环状管网非稳态工况的水力计算模型,突破了以往采用拟稳态管网水力计算方法研究非稳态工况的情况。
