Forecast and optimisation device for the mode control of a pumping station

Pumping units of the country use more than 300 billion kWh of electricity annually, i.e. more than 20% of the whole amount of electricity generated by the electric power network of the country (Leznov, Saving energy in pumping installations, 1991). In accordance with the requirements of the energy efficiency law, consumers should save energy in their companies. Water supply companies face a problem of low efficiency of the main technological equipment, such as pumping units supplying water into the network, and sewage pumping stations. A possible solution of this issue might be the optimisation of energy consumption by selecting the most appropriate model for the pumping unit control. Generally, the accepted way of improving energy efficiency of pumping units is by the introduction of the variable frequency drive (VFD), which provides a significant reduction in electricity consumption.
