Objetivo
To optimise the hydroelectric potential at the San Miguel hydroelectric power station by installing equipment to generate from water flow which is later spilled into the Bao reservoir.
By means of a Pelton turbine with two injectors, the plant works with variable flows ranging from 150-2, 100 l/sec. and a high efficiency.
A "TEAM" electronic regulator has been used for plant automatism. This regulator was especifically designed for synchronous groups. It performs, among others, the following functions :
- Start/stop automatism
- Manual control coordination
- Signalling
- Alarms
- Automation of ancillary elements
- Turbine regulation before coupling
- Synchronization
- Regulation by level after coupling
- Tension regulation
- Power-factor regulation
This plant has obtained most satisfactory results. This has been so much the case that it has alredy been resolved to use an analogus design in other plants to be built in the future.
A Pelton turbine will be installed at the new Cernado Power Station, to generate energy from water transferred from the river San Miguel to the Bao reservoir. Thus, both the Cernado and Bao heads (135+362m) will be utilized, limiting operation of the old San Miguel Power Plant (260m) to the turbining excess flows.
Technical details :
head : 135m
flow : 0.2/2.0 m3s-1
rating : 2360 kW
turbine : Pelton
The plant will run automatically and be controlled remotely. It is hoped to validate the suitability of the present design of Pelton machine to operation over a wide range at a constant head and to confirm the suitability of the system for remote control. The electricity produced will be sold to the national grid.
