Comparative assessment of the estimated and actual energy consumption of sewage pumping stations

Summary

The introduction of energy-efficient solutions, systems for the technological process automation and seasonal fluctuations in the wastewater flow directly affect the operation of power supply systems for sewage pumping stations, of them pumping units being the main consumers. Changing the operating mode of pumping units has the greatest impact on the amount of energy consumption of pumping stations. Most of the existing methods for calculating the power consumption of industrial facilities were developed in the 1990s, hence the most important reference values of the use and demand factors have remained unchanged since their development. Comparison of actual and design data of energy consumption of operating pumping stations is given. The difference between the actual and design values of electrical energy consumption indicates the need to improve the existing calculation methods. Estimated methods for calculating energy consumption based on the process characteristics of pumping stations were formulated and tested, the results of which showed the closest value to the actual energy consumption of sewage pumping stations.
