“…In the slip test, it is very hard to obtain a suitable slip in salient poles machines provided with damper windings due to their induced currents and resulting pulsating torque, always tending the machine to pull into synchronism. In addition, high voltage in the open field winding and high current in the dumper windings are induced when slip is large [5].…”

This paper introduces the constant excitation test to be applied in synchronous machines. The results obtained from this test allow the determination of the quadrature axis synchronous reactance of the salient pole synchronous machines. Despite standard present methods for its determination, the proposed method is suitable for large installed machines. The method basis is described and it is applied to several existent hydrogenerators. The calculated quadrature axis synchronous reactances are compared with the values supplied by the manufacturers, resulting in very good agreement. The appendix shows the quadrature axis location from the previous calculations results to obtain transient parameters from load rejection test.

“…Machine modeling with its physical dimensions requires a deep knowledge of the machine design, applied material, and construction [7]- [9]. Recent techniques have been presented to obtain machine synchronous and transient parameters, which include time domain and frequency responses [13]- [15].…”
