Magellan Power develop a containerised battery backup system to control water hammer effect

Battery system for W.A. Utility
  
The utility Magellan Power completed this project for is the principal supplier of water, wastewater and drainage services throughout the state of Western Australia. The company operates 112 wastewater treatment plants across Western Australia

The water utility wished to upgrade its wastewater plant with replacement pumps of higher capacity than the existing system. The surge analysis of the pressure main however, revealed that a full vacuum was likely to occur throughout the pipeline network during pump trips during which the maximum pressure could significantly exceed the allowable limits resulting in water hammer effect


The Magellan Solution


A pump trip scenario will occur when there is a power loss from grid network which does not allow the VSD to ramp down the pump to mitigate a pressure surge leading to water hammer effect resulting in potential damage to the pipeline system.

It was proposed to design and develop a battery backup system to allow the VSD (Variable Speed Drive) to ramp down in a controlled manner in the event of a power loss. The purpose of this R&D project is the analysis of deploying an Uninterrupted, Chopper Controlled, Variable Frequency, Variable Speed drive to prevent water hammer from damaging pumps and pipes.

Installation

Once the containersed system was manufactured, the focus of the Magellan team moved to getting the unit on-site for commissioning, this involved the delicate process of transporting the unit across Perth from Magellan Powers' Bibra Lake facility to the wastewater treatment plant.

Once on-site, the Magellan Power commissioning team then 
installed & tested the batteries & connected and tested the power systems, working closely with the utility to facilitate the handover of this critical equipment.

Director of Magellan Power, Masoud Abshar said “This is yet another example of using stored energy in a battery to mitigate sudden interruptions to electrical power which can cause damage to industrial installations. At Magellan we have thirty years’ worth of solutions to help with power interruptions”

Testimonials

Magellan Power has been our supplier of industrial battery chargers for a number of projects which require uninterrupted DC power for high voltage protection, automation and power generation. The customer service is always excellent, and the quality of their products is unparalleled.

Luke Del Paggio | Everett-Smith & Co.

Schneider Electric have used Magellan Chargers for its’ various projects in WA, and Magellan Services have been excellent. Well done Magellan!

Joseph Tjo | Schneider Electric

Magellan has supplied us with UPS for a range of projects and we found their service to be firstly cost effective, secondly the back up support is good and the supplied equipment of a good standard.

Rick Krause | Ergon Energy

Brookfield Rail’s Merredin office regularly sources power chargers from Magellan Power, and we always find it an easy process for new purchases and repairs. Their Sales & Repair Manager Shijo is prompt with responses to our queries, and on one occasion travelled to Merredin to meet with us, which we found extremely helpful.
