Transient Eerformance of 3-Phase Inductor-Type Synchronous Generator II-Uusymmetrical Short Circuits

The line-to-ground short-circuit case of an inductor-type synchronous generator is solved. Modified a, ß, 0 components have been used to formulate the basic differential equations of the alternator, which can be solved approximately to yield short-circuit currents. As compared to conventional synchronous machines these types of generators have lower short-circuit currents, and higher transient reactances. The short-circuit currents also decay at a comparatively faster rate than the normal synchronous machines.
