CONCEPTION OF STANDART FRANCIS TURBINE RANGE OF POWER BELOW 300 KW

Obiettivo

The project objective is to carry out, in full scale, a Francis turbine type which will be used for development base of complete standart range. This range will be a complement of an other, Kaplan type, actually build by THEE.
This future range allow to answer at many request received by THEE for site equipment whose the head is over the capacity of actual range wether above 18 meters.
The maximal electric power would limited at 300 kW. Limit power value above which it is existing many other manufacturers.
Net head : 18.1 m
Nominal flow : 1480 l/s
Electrical power : 205 kW
Speed : 760 t/mn
Output at 31/12/1996 : 332.000 kWh.
The program objective has been perfectly respected : the efficiency of turbine is 85%. The sale price of turbine is between 2000 to 4000 FF per kW and the installation working since 18 months without problem.
The product seems perfectly adapted at the market since 3 turbines are already sale.
A range half standardised has been developed come with complete set of technical documents. This range permit to offer competitive price and shortly manufacturing.
Technical context :
The project is based on utilisation of known technology (francis runner) but placed in configuration adapted at power below 300 kW, the objective is to create a standart range. Indeed it is impossible to plan a turbine of 100 kW like one of 1000 kW. Simplifications and standardisation are necessary to limit cost and saling price.
Main lines project are the following :
- Creation of range for the head between 20 to 80 meters.
- Considerable standardisation by commun sub assembly.
(shaft assembly, butterfly valve, chassis, guide vanes...)
- Complet setting of unit turbine/generator at work shop so as to limit the operation of site erection. - Determining of range half standardized by creation of sub assemblies.
- To define several standart type of establishing (vertical, horiozntal, spiral case, water chamber) so as to adapt at many cases.
- To suggest a product financialment adapted at small power.
- To find the good balance between a good efficiency and a simplicity of manufacture.
- To suggest, in parallel, a simple electrical automatism, standart, specially adapted at this type of turbine.
Demonstration site :
Demonstration site is located in department des VOSGES, at PLOMBIERES on trbutary of SAONE, the SEMOUSE.
It is an existing site which is furnished energy to a wood shop during many years. There is general installation. Dam with sluice gates, penstock (diameter 1100 mm), down stream channel, turbine and electrical cubicles.
The original characteristics are the following :
Gross head 20.70 meters
Nominal flow 1500 l/s
Estimated electrical power 190 kW

Final economics side :
Total amount of project 1.763.469 FF
Annual income 240.000 FF
External expenses 30.000 FF
Rentability 7.1 years
