WIND POWER

The wind power panel is for the simulation of a real wind power plant. The development was done in cooperati-on with cooperati-one of the leading manufactuers for wind power plants.

Automatic Mode:

Settings of nominal values are done either on integrated

potentiometers or external sensors.

Setting for Wind Direction:

• Integrated Graycode Switch

• External Graycode (4bit or 8bit)

• 4-20mA • 0-10V

Setting for Wind Speed:

• 0-10V • 4-20mA • PWM-Signal

Setting for Degree of Daylight:

• Internal LDR

After entering all nominal values, the panel operates completely autarc and simulates all options of a real wind power plant.

• Pitch-adjustment (rotor blade), depending on the wind force between 0° (full surface) to 90° (break).

• Azimuth tracking (wind direction), depending on the wind direction the azimuth is automatically positioned. • The rotation speed of the rotor changes with the wind speed.

• Change between day - and night light (warning light for aviation) with respect to the degree of ambient daylight.

• Drivetrain break for emergency stop mode.

All functions in case of emergency stop, service mode and power failure could be simulated with switches.

A 7-segment-display indicates the actual wind speed, rpm of the rotor and the generated and consumed power.

Manual Operation (Optional):

In manual operation the overall automatic controls are disabled. Now all actuators could be controlled by SPS and all integrated sensors could be read out, connection is done to SUB-D socket.

Actuators:

• Rotation speed of the rotor via PWM-signal • Pitch adjustment via PWM-signal

• Azimuth tracking via +24V left or right signal

• LED break • LED day light • LED night light

Sensors:

• Wind direction (Graycode) • Azimuth position (Graycode) • Service switch (24V) • Enable switch (24V)

• Emergency stop switch (24V) • Power failure (24V)

• Actual value rotation speed (pulses per minute) • Brightness sensor (0-10V)

• Wind speed (0-10V)
