ABSTRACT
Power system transient analysis is usually performed using computer simulation tools like the Electromagnetic Transients Program, although modeling using Transient Network Analyzers is still done, but decreasingly. This chapter summarizes the capabilities of present simulation tools to obtain models considering the different approaches for parameter determination. It provides a summary of modeling guidelines for the representation of the most important power components in transient simulations taking into account the frequency range. There is a family of tools based on computerized real-time simulations, which are normally used for testing real control system components or devices such as relays. The simulation of the asymmetrical behavior that can be caused by some transients must be based on models for which no standard has been yet developed, although several tests have been proposed in the specialized literature. The increasing capabilities of simulation tools and computers are a challenge for developers, and more sophisticated and rigorous models will be developed and implemented at lower costs.
