Abstract |
In this study, surge analysis was performed to investigate the risk for overflow in a pump station of power plant with different design cases. In case of a reference model with intake bay length of 36 m, the water level of pump station increased to a maximum of 4.1 m if all intake pumps stopped. This result means that there is no overflow at the pump station, the launching shaft, or the end shaft. In case of alternative model with inlet bay length shorter than the reference model by 9 m, there was no possibility of overflow occurrence since the water level of pump station increased up to 4.4 m. If four pumps were tripped, the water level of pump station increased under the height of structure in both reference and alternative models. It was found that the stability of sea water intake system could be secured in spite of a reduction of inlet bay length for construction cost reduction. |
