To control the excitation system of a synchronous generator with an excitation system controller, the controller is connected to the generator’s field winding. The controller then monitors the generator’s output voltage and adjusts the field current accordingly to maintain a constant voltage. This helps to ensure that the generator operates at a stable voltage and frequency, which is important for the proper functioning of the power grid.

Here are some steps to consider when using an ABB excitation system controller:
- Connect the excitation system controller to the synchronous generator’s field winding.
- Set up the controller according to the manufacturer’s instructions.
- Monitor the generator’s output voltage and adjust the field current using the controller as needed to maintain a constant voltage.
- Perform periodic maintenance on the controller and generator to ensure proper operation.
