The related regulations of temperature rise test of autotransformer for autotransformer starter in IEC, GB were described, the current in every winding of autotransformer was analyzed. 3. Three-phase autotransformer with pure resistor load is chosed for the simulation experiments. 4. Subsequently, shunt capacitor banks and autotransformer starters are suggested to mitigate the impact, and simulation results prove that these measures are reasonable and effective. 5. For these reasons, the use of an autotransformer to interconnect a generator to its host system should be approached with caution. 6. An improved algorithm based on equivalent circuit of autotransformer -fed (AT-fed) systems was proposed to calculate power flows of electric traction networks. 7. They are autotransformer low-voltage starter, high-voltage transducer soft-starter and a dedicated transformer for the motor starting directly on line. 8.
