Introduction to Transients Analysis of Power Systems with ATP

Transient analysis has become a fundamental methodology for understanding the performance of power systems, determining power component ratings, explaining equipment failures, or testing protection devices. A rigorous and accurate analysis of transients in power systems is difficult due to the size of the system, the complexity of the interaction between power devices, and the physical phenomena that need to be analysed. Alternative Transients Program (ATP) was originally developed for simulation of electromagnetic transients in power systems. The ATP package is integrated by at least three tools: ATPDraw, a graphical user interfaces for creating/editing input files; TPBIG, the main processor for transients and harmonics simulations; and one postprocessor for plotting simulation results. The EMTP Theory Book, ATP Rule Book, and ATPDraw Reference Manual material will be of help when using any of the basic tools that constitute the package. The chapter also presents an overview of the key concepts discussed in this book.
