A visual tool to calculate optimal control strategy for non-identical pumps working in parallel, taking motor and VSD efficiencies into account

A simple graphical tool was developed, that finds the optimal combination of pumps and their rotational speeds for all possible working points for a pump battery. The tool was integrated into EPANET as well as EPA SWMM simulation packages. The tool allows us to analyse and optimize operation non-identical parallel pumps with different minimum and maximum frequencies for all possible working ...

TCU temperature control model selection and technical parameter description

TCU temperature control is also a two-cycle unit single-fluid temperature control system. When selecting the model, it is very important for the whole temperature control reaction. Only the appropriate reaction system is used to exotherm and absorb the whole reaction process. The heat responds to the entire control, so the choice of model is very important. TCU temperature control model: SR-10 ...

A robust approach based on time variable trigger levels for pump control

An approach for the control of a pumping plant feeding a tank at the inlet of a water distribution system is presented. The approach is aimed at minimizing the energy costs by maximizing pumping during off-peak electricity tariff periods. It is based on trigger levels which are variable during the day according to a prefixed pattern in order to ensure that the water level in the elevated tank ...

Frequency pressure regulation in water supply systems

In water supply systems, pressure management in most cases is proven to be the most cost-effective activity related to water loss control. As an advanced method of pressure control, it is possible to use variable frequency drives for centrifugal pump control. Pressure regulation can be performed with constant pressure or with proportional pressure control. The application of proportional ...
