Paralleling synchronous generators requires a priori voltage matching and frequency synchronization. Exceeding normal limits can lead to severe electrical transients. The classical three-phase short circuit analysis is extended to include the case of two initially unloaded synchronous generators. An analytical solution is developed neglecting winding resistances and saturation. Of particular interest is the tendency to induce negative field currents that cause inverse voltages across the rotating rectifier in a brushless design. Typical aircraft generator parameters are used to predict the paralleling transient vs. initial rotor electrical angle mismatch. Results are compared to simulation and limited test results.
