Power System Blockset

Synchronous Machine and Regulators

This case study investigates the application of a multi-input multi-output nonlinear controller to a system consisting of a hydraulic turbine and a synchronous generator connected to an infinite bus. The complete system is modeled using the Power System Blockset and Simulink blocks.

The objective of this case study is to demonstrate the use of the Synchronous Machine block connected to a complex control system implemented with Simulink blocks. The controller is based on a feedback linearization scheme. Its main goal is to control the rotor angle as well as the terminal voltage, to improve the stability properties, and to obtain good dynamic response. Simulation results will show that the nonlinear controller is able to replace the standard linear controllers and give better performance.
