Real time simulation of a synchronous machine in a programmable high speed controller

摘要

The real-time simulation of a synchronous machine in a microprocessor based programmable high-speed controller (PHSC) is presented. The simulation is based on the normalized equations of the machine in the d-q reference frame. The system presented can be used as a generator in HVDC simulation as well as to study the effects of various excitation control techniques. It can also be used as a motor simulator to study the various closed-loop control strategies in variable-speed drive applications. The dynamic behavior of the simulator is illustrated by results of open- and short-circuit tests, by network synchronization, and by response of excitation control.
