Alat Peraga Pendidikan Teknik Mesin | Computer Controlled Generating Stations Control and Regulation Simulator
DESCRIPTION
Unit designed to simulate the regulation behaviour of a hydroelectric generating station, as a didactic application with different aspects of regulation, control and simulation.
It is possible to work with this unit in 2 ways:
• REAL mode (continuous or transient analysis).
• SIMULATED mode.
The unit consists mainly of an interface for the conditioning of input and output signals. For its part, this one will be connected to the computer (through a SCSI wire and a data acquisition board) and to the two subsystems that we try to control:
Gate subsystem.
Turbine-generator subsystem.
The unit has (in the interface) some switches to establish different loads to the generator output and different conditions of the real system.
SPECIFICATIONS
• SCE. Unit:
Bench-top unit.
Metallic box and main metallic elements in stainless steel. Diagram in the front panel with similar distribution to the elements in the real unit. It is possible to work with this unit in 2 ways:
• REAL mode (continuous or transient analysis).
• SIMULATED mode.
The unit consists mainly of an interface for the conditioning of input and output signals. For its part, this one will be connected to the computer (through a SCSI wire and a data acquisition board) and to the two subsystems that we try to control:
Gate subsystem.
Turbine-generator subsystem.
The unit has (in the interface) some switches to establish different loads to the generator
output and different conditions of the real system.
Gate subsystem:
It consists of a motor that controls the gate opening, and some mechanisms that
emulate it.
The control tension to command the gate’s motor will be range between 0 and 10 volts. The gate’s motor is coupled, by one side, to a dynamo, that will give us a signal proportional to its own rotating velocity, and by the other side to a reduction gear.The dynamo (Dynamo Gate) gives us a voltage that is proportional to the motor’s rotating velocity.Near the output of the reduction gear there is a potentiometer that gives us an output in volts proportional to the position where it is located, simulating the opening degree of the gate.Turbine-generator subsystem:
This subsystem will be analyzed separately or linked up with the previous one, achieving that the
motor that simulates the turbine turns according to the gate opening percentage.
This turbine is connected with a generator system and with a system of different loads (inductive, capacitive and resistive). Three loads in parallel are connected at the generator output, that simulate the consumption of the energy distribution system:
Variable resistance (270-770 W approx.).
Capacitance (1000 mF).
Inductance (100 mH).
Control interface.
