HYDROMATRIX® An innovative way to hydropower generation Conventional

HYDROMATRIX®



An array („Matrix“) of small turbines instead of conventional sized turbines



Best suited for low head sites with existing dam and weir structures



Most ost econom economica icall in larger larger numbers numbers -> ->not a typica typicall „ „s small hydro“ hydro“ application application

HYDROMATRIX® Advantages 

HYDROMATRIX® Differences HYDROMATRIX® vs StrafloMatrix TM HYDROMATRIX® 

Simple Bulb Design



Synchronous or Asynchronous Operation



Perm. Magnets or Conventional Rotor Winding





StrafloMatrix™ 

Generator outside of flow (straight flow)



Synchronous Operation



Permanent Magnet Technology



Shorter, Less Weight



No PF Compensation required

Longer, Heavier than StrafloMatrix™ PF Compensation (for asynchronous version only)

HYDROMATRIX® Operation Aspects 

Maintenance intervals 





BOP Equipment: 

According to maintenance schedule



UW - Cables: Change every 10-12 years

 Accessibility 



 TG-Units: Annual Oil Inspection / Change

Easy access to all maintenance-relevant components without disturbance of overall plant operation

Expected life time 

Identical to conventional hydropower concepts
