Computer models for complex plant based on terminal measurements

A method for obtaining models of a complex plant and systems for use in transient voltage studies is described. The method is based on determining the terminal impedance/frequency characteristics of the plant or system under study over a wide frequency range. This characteristic is obtained from measurements performed at sampled frequencies with a programmable impedance meter and a microcomputer. The use of the method for performing a high-speed switching transient calculation for a cable/motor system is illustrated and the results are compared with experimental records.<
