Transient Stability - Objective

This document is a user's guide for real-time simulation used to study transient stability in power systems.

A basic example of a power grid composed by an infinite bus, a synchronous generator, a transformer and four buses is studied and simulated in both normal and fault operation. In addition, the impact of damper windings on the synchronous generator rotor is highlighted by comparing the generator performance with and without damper windings. A power system stabilizer (PSS) is added, which stabilizes the system after a fault and returns it to normal conditions before continuing to the next exercise.

A user interface is provided to interact with the system in real time and run the tests step-by-step.

Finally, the grid is analyzed in (i) time-domain mode and in (ii) phasor mode, which allows users to explore and understand both power systems analysis methods.

The introduction of the manual describes the pedagogical approach proposed to realize the exercises and improves the understanding of transient stability in power systems. A description of the simulated grid, with all its parameters, is presented in Part 2.

The simulator panel, which provides the interactive interface between the user and the virtual grid, is described in detail in Part 3, which is the complete reference for all components in the front panel and users can refer to this section during the exercises.

Part 4 describes the procedures for the three exercises on the transient stability in power systems.
