Automated mini hydroelectric station.
MINI HYDROELECTRICAL STATION
The suggested system includes:
Turbine-generator unit activated by a forced-pressure closed water
circuit.
Three-speed horizontal stainless steel multistage centrifugal
electrical pump.
Steel water tank.
Inverter for the electrical energy transformation produced at
standard mains values.
Control and supervision panel, with possibility of telemeasurements
of the electrical variables (voltage, current, power factor, frequency
and consumption) connected to a personal computer; analog
instruments (voltmeter, ammeter). It enables to regulate two
programmable outputs for the system control and a unit for the PC
conversion: RS485/RS232.
