Transmission of Electrical Energy: Overhead Lines takes a computational approach through the use of the Alternative Transient Program (ATPdraw), which is a program of worldwide use. The number of exercises solved, including computer simulations with ATPdraw and source codes in MATLAB® make the work didactic and easy to assimilate, even for those readers new to the subject. The subjects presented throughout the text aims to make the reader understand and gain sufficient knowledge to analyze the operation of overhead transmission lines in a steady-state and in a transient state, besides carrying out an introductory project of a steady-state transmission line. The book can be used in both undergraduate and graduate courses in electrical engineering.

ATPdraw Program

1.1 Introduction

ATPdraw is a preprocessor for the alternative transients program (ATP), resulting from cooperation between the Bonneville power administration (BPA) of Canada and the Norwegian Electric Power Research Institute of Norway, which developed ATP for the Windows operating system environment. ATPDraw output is a file that is used as input to the ATP program.

1.2 Resolution Algorithms

The first studies related to the digital simulation of traveling wave problems in power systems were conducted in the early 1960s using two techniques: the Bewley diagram and the Bergeron method. These developed techniques were applied in the analysis of small networks with lumped, linear or nonlinear parameters and distributed parameters. The extension to multi-node networks was done by Hermann W. Dommel, which resulted in BPA's electromagnetic transients program (EMTP) and later alternative transients program (ATP). The scheme developed by Dommel combines the Bergeron method and the trapezoidal r...
