500kw Turgo Hydro Turbine Generator For Micro Hydro Generator

overview

Turgo impulse turbines are well suited to power generation in South East Asia. Their robust design features and simple construction provide good reliability and availability. Machine efficiencies are maintained over a wide flow range and progressive efficiency reductions due to erosion by silt present in the water are minimal.

The simple and robust Turgo Impulse turbine provides reliable power generation even on water supplies with silt burdens.

It offers a number of advantages particularly over reaction turbines especially in SE Asia that have been covered above.

The Turgo has a higher specific speed than Pelton turbine resulting in smaller

faster rotating turbine generator unit for a given head and flow

High tolerance to erosive particles in the water with no significant reduction in efficiency

Low maintenance design

Deflector speed control giving a fast response to load / frequency changes

Modular design approach

Flexibility in turbine design, layout and configuration

No penstock surge in response to a change in load or frequency

No penstock surge on emergency shutdown on loss of grid

Operation possible down to 10% of rated flow

A higher annual energy may be possible than is available from reaction turbines

on projects with long periods of low flow

Advantages 

Covers the boundary between Francis and Pelton

Limits Over-Pressure Effect over the penstock

Higher speed = weight and cost reduction

Maintains efficiency over a wide flow range

Superior abrasion resistance

Ease of operation and maintenance
