| Abstract: | A mathematical model for calculation of dynamic characteristics of a low-head pump station during its suspending period was developed based on the pipeline characteristics of the pumping system. The principles of the energy conservation and the similarity theory combined with the eigenpoints in the hydraulic transients curves measured during suspending period were employed in this modeling procedure. |
| Keywords: | Pumping station Dynamic characteristics Energy conservation Mathematical model |
