Objective
Increasing production self-sufficiency through:
. automation of remote power stations
. data acquisition and transmission from each power station to a central unit
. setting-up of a program for a maximum effective operation of power stations
. remote control and adjustment of power stations of power stations and plant.
Even though in the years 1989-1990 there was a reduction in the amount of both rain and snow precipitation equal to 30%, and periods of considerable drought with consequent reduction of the average yield equal to 3-15%, the results were comforting and fully fulfilled the expectations.
1) Production surplus exceeding the 1,000,00 kWh forecast. Note: In the calculation of the delta-Q an average annual production of 29,200,000 kWh was assumed, decremented by 5-10%.
2) The per kWh cost of self-reduction was kept around the forecast amount of Lire/kWh 55 (reduction of labour/production costs and exceptional maintenance work).
3) Commitments made by contract to ENEL were kept, in spite of reduced self-production and the stability of power consumption.
The Cogno Olcese factory produces cotton yarn and consumes nearly 50 million kWh/year. The electric energy is partially purchased from ENEL and consumes auto-production in hydro-electric power stations located in Campione, Artogne, Cogno, La Rocca.
The present operation of electric power stations is manual or semiautomatic (Campione).
To fulfil project objectives the following is foreseen:
- local survey of running conditions in power stations
- automation of remote power stations
- centralisation of all data acquisition in a master unit meant to establish the optimum running periods for each power station
- Master unit intervention for:. automatic start-up and shut-down of power stations. control of factory electrical loads. alarm management. energy consumption management
The project allows:
- optimum exploitation of water supply preventing overflow in periods of abundant water supply and optimum use of water basins in dry periods
- optimum use water-supply according to multi-band tariffs
- forecast of water availability according to: flow, supply in different basins, use by each station and power needs in factory
- control and smoothing of power peaks in factory
- control and compensation of malfunctioning in a self-production group
- programming optimum use of stations according to changes in production and or in process.
- maintenance and operating control of the electric system of plant and stations
- adjustment of turbines in working conditions nearing peak efficiency.
