ANDRITZ HYDRO 2012 www.andritz.com2

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

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

Most economical in larger numbers -> not a typical small hydro application

HYDROMATRIXAn innovative way to hydropower generation

Conventional

6+ m

HYDROMATRIX

1.3+ m


3/55


Available plant discharge from ~ 60 m/s

Available head from 2 m up to 25 m

Minimum submergence 1.5 m below tailwater

Unit output from 100 kW up to ~ 1500 kW

Grid connection in close vicinity

Structure available & suitable for HYDROMATRIX

HYDROMATRIXApplication criteria


4/55


Use of existing weir structures

No major civil construction> less cost

Little excavation & no coffer dams> less geological risk

No additional land usage -> environmentally friendly

Existing river flow pattern can be maintained

HYDROMATRIX Modules removeable at flood conditions

Standardized modular concept

Compressed project schedule

High availability & easy maintenance

HYDROMATRIX StrafloMatrix

Generator outside of flow (straight flow)

Synchronous Operation

Permanent Magnet Technology

Shorter, Less Weight

No PF Compensation required

Simple Bulb Design

Synchronous or Asynchronous Operation

Perm. Magnets or Conventional Rotor Winding

Longer, Heavier than StrafloMatrix

PF Compensation (for asynchronous version only)

Maintenance intervals

TG-Units: Annual Oil Inspection / Change

BOP Equipment:

According to maintenance schedule

UW - Cables: Change every 10-12 years

Accessibility

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

operation

Expected life time

Identical to conventional hydropower concepts
