- Let us describe first the main items (1 to 6):
- 1ECMC. Unit:
Unit designed for simulating an energy generation system from the ocean currents, using the technolgy
of turbine-driven generators anchored in place into the current stream.
This unit is mounted in an anodized aluminium structure with painted steel
panels.
Diagram in the front panel with similar distribution to the elements in the
real unit.
Main metallic elements are made in stainless steel.
- The unit is formed by the following main elements:
Transparent working channel to be filled with water. Includes level switch.
- Drive system consisting of:
Intermediate storage tank. Includes level switch.
Main drive pump to the channel, computer-controlled.
Pump for suction and filling of the tank, computer-controlled.
Generator-turbine anchored in the channel.
Flow meters installed at key points in the circuit.
Pressure sensors at the outlet of each pump for protection and safety.
DC loads module.
Power measurement from the computer.
- The complete unit includes as well:
- Advanced Real-Time SCADA. Unit: ATENG 11528
Open Control + Multicontrol + Real-Time Control.
Specialized Control Software based on LabVIEW.
National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
Calibration exercises, which are included, teach the user how to calibrate a sensor and the
importance of checking the accuracy of the sensors before taking measurements.
Projector and/or electronic whiteboard compatibility allows the unit to be explained and
demonstrated to an entire class at one time.
Capable of doing applied research, real industrial simulation, training courses, etc.
Remote operation and control by the user, as well as remote support from technical
support, are always included.
Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
Designed and manufactured under several quality standards.
Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
calculations, etc. Apart from monitoring user's knowledge and progress reached.
This unit has been designed for future expansion and integration. A common expansion is
the Scada-Net (ESN) System which enables multiple students to simultaneously
operate many units in a network.
- ECMC/CIB. Control Interface Box:
The Control Interface Box is part of the SCADA system.
Control interface box with process diagram in the front panel and with the same distribution that
the different elements located in the unit, for an easy understanding by the student.
- All sensors, with their respective signals, are properly manipulated from -10V. to +10V. computer output.
Sensors connectors in the interface have different pines numbers (from 2 to 16), to avoid
connection errors.
Single cable between the control interface box and computer.
The unit control elements are permanently computer controlled, without necessity of
changes or connections during the whole process test procedure.
Simultaneous visualization in the computer of all parameters involved in the process.
Calibration of all sensors involved in the process.
Real time curves representation about system responses.
Storage of all the process data and results in a file.
Graphic representation, in real time, of all the process/system responses.
All the actuators’ values can be changed at any time from the keyboard allowing the
analysis about curves and responses of the whole process.
All the actuators and sensors values and their responses are displayed on only one screen in the
computer.
Shield and filtered signals to avoid external interferences.
Real time computer control with flexibility of modifications from the computer keyboard
of the parameters, at any moment during the process. ECMC/CIB
Real time computer control for pumps, compressors, heating elements, control valves, etc.
Real time computer control for parameters involved in the process simultaneously.
Open control allowing modifications, at any moment and in real time, of parameters involved in the
process simultaneously.
Three safety levels, one mechanical in the unit, another electronic in the control interface and
the third one in the control software.
