Water Plant Installs Standby Power System
A new 5 MW standby power system installed at the Wyoming (MI) Water Treatment Plant features two new PowerCommand® 2.7 MW diesel generators from Cummins Power Generation.
A new 5 MW standby power system installed at the Wyoming (MI) Water Treatment Plant features two new PowerCommand® 2.7 MW diesel generators from Cummins Power Generation. Introduced in the fall of 2002, the diesel generator sets have a high-power output and a small footprint in addition to having low emissions and high fuel efficiency.
The Wyoming Water Treatment Plant serves Wyoming, MI, (a large suburb of Grand Rapids) and a number of other municipalities. With a population of 70,000, Wyoming is the 16th largest community in the state. The city draws water from Lake Michigan approximately 30 miles to the west. Most of the electrical load at the treatment plant is from pumps – some as large as 2,000 horsepower.
In order to provide a constant source of water for the communities, the water treatment plant needs a highly reliable electric supply. While the plant already had power feeds from two separate utilities, the new Cummins standby power system adds yet another level of redundancy should one or both utility feeds fail. The power system can also operate in an interruptible mode by running in parallel with either utility feed, thus permitting the plant to shed some or all of its electrical load when requested. Plants on interruptible electric service usually pay lower utility rates.
Designed and installed by the local Cummins distributor, Cummins Bridgeway, the power system consists of the two diesel generator sets with the new PowerCommand 3200 controller and model 300 paralleling master control. These pre-integrated digital components monitor hundreds of system functions, provide precise control of voltage and frequency, and allow remote operation and monitoring. The power system also has four generator paralleling breakers operating in conjunction with the two utility mains.
As configured in this power system, each generator's output is rated at 2.5 MW. The generators can operate individually or together in parallel with the utilities; or the system can provide all the power necessary to operate the plant if both utility feeds fail.
