Computer Controlled Power Plants Regulation and Control Unit Deluxe

The Computer Controlled Power Plants Regulation and Control Unit, to study the modeling and simulation process of power generation in a plant, as well as to validate the model’s behavior against the real system in a safe and controlled way.

ATENG 12649 — Computer Controlled Power Plants Regulation and Control Unit

(for main items)

• With this unit there are several options and possibilities:
• Main items: 1, 2, 3, 4 and 5.
• Optional items: 6, 7, 8 and 9.
• Let us describe first the main items (1 to 5):
• 1SCE. 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 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.
• Unit: ATENG 12649
  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).
• The complete unit includes as well:
  Advanced Real-Time SCADA.
  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.
