1 SCE. Unit:
Anodized aluminum structure. Main metallic elements in stainless steel.
Diagram in the front panel with similar distribution that the of the elements in the real unit.
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.
Gate subsystem:
It consists of a motor that controls the gate opening, and some mechanisms that emulate it.
Turbine-generator system:
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 that simulates different loads (inductive, capacitive or resistive).
Three loads in parallel are connected at the generator output, that simulate the consumption of the energy distribution system:
Variable resistance.
Capacitance.
Inductance.
Control interface.

Maximum output rate up to: 833 KS/s.
Output range(V)=±10.
Data transfers=DMA, interrupts, programmed I/0.
Digital Input/Output:
Number of channels=24 inputs/outputs.

3 SCE/CCSOF.Computer Control+Data Acquisition+Data Management + Simulation Software:
Compatible with actual Windows operating systems. Graphic and intuitive simulation of the process in screen.
Compatible with the industry standards.
Registration and visualization of all process variables in an automatic and simultaneously way.
Flexible, open and multicontrol software, developed with actual windows graphic systems, acting simultaneously on all process parameters.
Management, processing, comparison and storage of data.
Sampling velocity up to 250,000 data per second guaranteed.
Student calibration system for all sensors involved in the process.
It allows the graphic representation in real time.
Comparative analysis of the obtained data and modification of the conditions during the process.
Open software, allowing to the teacher to modify texts, instructions. Teacher’s and student’s passwords to facilitate the teacher’s control on the student, and allowing the access at different work levels.
This software has got 2 operating modes:
REAL mode: Through motors, actuators and sensors that the unit includes (Continuos, transient).
SIMULATED mode: through the mathematical modelization of the motors, previously mentioned.
This unit allows that the 30 students of the classroom can visualize simultaneously all results and manipulation of the unit, during the process, by using a projector.

4 Cables and Accessories.
5 Manuals:
This system is supplied with 8 manuals: Required Services, Assembly and Installation, Interface and Control Software, Starting-up, Safety, Maintenance, Calibration & Practices Manuals.

Q References 1 to 5: SCE + DAB + SCE/CCSOF + Cables and Accessories + Manuals are included in the minimum supply, enabling a normal operation.
