Electricity is primordial for basic sanitation development, and this sector was responsible for
2.4% of Brazilian energy consumption in 2015. In our recent scenario, seeking for more
energetic efficient processes is mandatory for reducing the environmental impact as well as
costs incurred from a lower energy consumption for companies responsible for public
sanitation. The objective of this current study was the evaluation of energetic efficiency
technique for pumping systems. A Variable Frequency Drive was installed to vary the engine
rotation aiming to reduce the flow rate when compared to the standard usage of a flow control
valve. The analysis was made on a system of water supply in the municipality of Palmas-TO
where a 100hp motor was ignited by a soft starter. This study monitored the following
parameters: power, flow rate, pressure, pumped water volume and system energy consumption;
this allowed proving the efficiency of the usage of the variable frequency drive which increased
the system yield as well as reduced energy consumption in approximately 22%. It was then
concluded that on systems where there are flow rate restrictions by valves it is economically
feasible to install a variable frequency drive and the payback for the initial investment will come
in power savings, to the case in question the payback is 10 months. |
