| Abstract: |
| With the purpose to increase the operational efficiency of the main transformer and decrease the pumping energy loss in pump stations,combined with the engineering example of the Nanshangzo pump station,the operational conditions of the main transformer in pump stations are thoroughly analysed in terms of the relation between the loss and load rate,efficiency and load rate as well as efficiency and power factor.The results indicate that when the capacity of the main transformer of pump station and the power of the units are certain,increasing power factor of pump station will decrease the load rate of the main transformer and the operational efficiency of the transformer will be increased. |
| Key words: pump station transformer operational efficiency load rate energy conservation |
