Small-scale Renewable Generation Control Circuit

Description:

You are required to design a small-scale control circuit for a low power wind generator system. There is a dc generator (acting as wind turbine) which is coupled physically to a prime mover (acting as wind), producing dc voltage across the generator's terminals. The generator is connected to a very simple (resistor-based) load (acting as a household).

The wind speed is subject to unexpected changes (just like what happens in real life applications), leading to unstable voltage across the generator terminals. Therefore, the control circuit should be able to detect the undesired voltage changes and adjust the load accordingly, so the household appliances do not get damaged by the unexpected voltage surge/drop. Your VI should be able to:

- Make a user interface that can change the speed of the prime mover (simulating the wind behaviour). So the user will be able to change the speed of the wind and evaluate the response of your circuit to those wind disturbances.

Measure voltage and current at the output of the generator and illustrate it in the front panel. This includes adding waveform graphs and charts to visualize relevant information.

Perform necessary calculations of power quality (e.g., voltage, current, etc).

Adjust the output voltage so you will have a stable voltage across the load terminals. This encompasses introduction of a control loop.

Perform signal processing tasks to visualize useful technical information to illustrate more details about the system status (frequency of wind oscillations, Fourier transform, etc).

Important notes:
• You will be given the required hardware equipment such as DC motor, NI myDAQ, jumper wires, breadboards, etc.

• The project scope is not restricted to the above-mentioned requirements. You have freedom to add more features wherever you think would be beneficial.
