Keywords:
synchronous machine, electrical parameters, platform, transient reactance, sub-transient reactance.Abstract
This paper deals with the design and implementation of a platform by means of sensors and a data acquisition board that allows to visualize real time variables and obtain parameters of the tests applied to synchronous machines in dynamic state. In particular, it is used in smooth-pole synchronous machines in which, as a case study, the three-phase short-circuit opening test and a sudden short-circuit test on the stator windings are carried out in order to calculate the transient direct shaft reactance, sub-transient reactance and permanent state reactance. Voltage and current sensors are used which capture and carry information to a National Instruments NI USB 6009 board that serves as an interface with the Labview® evaluation software in which the calculations and control and acquisition necessary to perform the calculations. The control schemes, design and implementation of the platform are shown, in addition to the algorithms and performance tests carried out on the prototype.
