Sorensen Governor Continues as Premier
Station Automation and Upgrade Provider
Sorensen Systems has over 50 years experience with new installations, refurbishment projects and hydro station automation for the hydroelectric, power generation, water and waste-water industries. It has established a reputation as a leader in the design and manufacture of electro-hydraulic governors, gate-operating systems, and hydraulic lubrication and bearing cooling units.
Sorensen Builds System Solutions
Its in-house staff of engineers and design technicians have extensive experience with applications ranging from turbine speed control to water level management. System design, fabrication, installation, start-up and field maintenance are provided for:
- High and low pressure electro-hydraulic
conversion systems
- Remote gate positioning systems
- Ball valve, butterfly valve and fixed cone
operating assemblies and systems
- Turbine lubrication and cooling systems
- Crest, slide and roller gate control systems
- Gas/steam turbine combined cycle diverter systems
- Electro-hydraulic governor control systems
Full Service Project Engineering
From its 60,000 square foot engineering and manufacturing headquarters in Massachusetts, Sorensen Systems works closely with its customers and with any globally recognized hydraulic and electrical component manufacturer to provide full service project engineering from initial concept through commissioning. Its team of mechanical, electrical, hydraulic, and pneumatic engineers, support customers in the following ways:
- We provide complete design
documentation
- We follow a compressed turn-around
design-to-production schedule
- We offer worldwide field assistance for on-site
engineering of special applications reducing installation
and commissioning costs
- We offer customized testing procedures at
our facility allowing the customer to put their
equipment to work sooner
Keeping the Water Flowing
When the Massachusetts Water Resources Authority determined that turbine generators at its Clinton MA location along the Wachusett Reservoir needed upgrading and refurbishment, Sorensen Systems was awarded the contract for the project. The two vertically oriented, full Kaplan type 1,600 KW generators with six adjustable runner blades and two 2,240 HP turbines had been in operation since 1969. The upgrade was necessary to integrate the turbine operation with a newly configured water supply system. The hydroelectric facility, locally referred to as the Cosgrove Intake, regulates the flow of water from the Wachusett Reservoir into the Cosgrove Aqueduct, which is an important transmission leg in the supply of water to the Boston Metropolitan area.
There are two sections, the North and South intakes, and both intakes include a hydraulic turbine and two bypass lines. Each intake has three channels with traveling water screens. Each intake also has an upper intake sluice gate and lower intake sluice gate that allow operational flexibility to draw water from different levels of the reservoir.
Hydro Station Automation
Sorensen Systems provided the design, manufacturing, installation supervision, commissioning and training for the entire project, which included the disassembly and refurbishment of the existing turbine generators, new static excitation systems, new turbine bearing cooling water systems, refurbished switchgear panels, new turbine control panels, new digital governor heads with the refurbished governor hydraulic pumping units and new station battery charging system.
