Transcription

1 Your solution for water and wastewater pumping stations Reduce your electricity consumption. Control your hydraulic networks remotely. Increase the life of your installations. On-site or remote operation of water infrastructure by optimised start-up, control and monitoring systems. Building a New ElectricWorld

2 Optimised solutions to control your installations and significantly reduce your electricity consumption Control operating costs Combine the automation, starting, control and monitoring of pump motors to maintain network pressure, avoid voltage drops during start-up and reduce electricity consumption. Increase the energy efficiency of the installation Optimise the process Integrate harmonic filters in the electrical installation to ensure energy quality. Add power factor correction systems to bring the installation in line with requirements of electrical utilities and avoid penalties. Control and monitor pumps to improve operation by controlling discharge, regulating pressure and uniformly distributing pump operating times. Design a selective electrical distribution system to increase installation availability and decrease power outage phenomena. Take immediate action via remote management Store, edit and transmit data in real time to handle emergencies quickly. Reconfigure the system remotely at any time, whatever the telecommunication system used. Increase the service life of hydraulic equipment Protect life and property Eliminate water hammer and protect pumps with an optimised electrical installation to extend equipment life. Use solutions that comply with the most demanding standards.

5 Did you know? The other advantages of pumping station solutions What are the advantages of variable s compared to traditional valve-based regulation systems? > Variable s control the power supply to the pump motor to adapt motor speed to the required flow rate and pressure. Combined with an asynchronous motor, these drives replace valves that control discharge by reducing the cross-sectional area of the pipe. In addition to complementary functions, drives offer energy savings of 25 to 30% by eliminating the very high head losses produced by valves. The elimination of regulating valves also simplifies hydraulic installations. What does electricity represent in the cost of operating a pumping station? > On the average, electricity represents 30 to 35% of the overall operating costs of a pumping station. For water supply installations, this value depends highly on the type of source : surface water, springs, groundwater, etc. How can I find out more about Schneider Electric solutions? > Ask for technical documentation and the complete catalogues.
