Instructional Use of Declarative Languages for the Study of Machine Transients

Abstract:

This paper illustrates uses of high level and declarative programming environments for the teaching of machine transients. It demonstrates the clarity and flexibility afforded by this new generation of mathematical software environments. Three environments are compared: Speakeasy, PC-Matlab, and SOLVER-Q. Results obtained using these environments are compared with simulations obtained using the Electromagnetic Transients Program (EMTP). Numerical results of simulations are similar, with minor differences between constant and adaptive time step programs. Execution times differed, with environments that emphasize symbolic computation slower than those that are able to perform numerical simulations alone. The paper also compares the clarity of the expressions needed to produce a simulation in each environment. © 1991, IEEE. All rights reserved.
