| Abstract: | Shorts in double-winding AC-DC generators were modeled by analogy to an ordinary 3-phase synchronous generator to predict the electromagnetic torque of a double-winding generator after a sudden AC and DC sides short circuit in the design stage.The double-winding generators were analyzed using a method for analyzing the electromagnetic torque after a sudden short circuit in a 3-phase synchronous generator. The analysis gives analytical expressions for the alternating and unidirectional electromagnetic torques as well as the total electromagnetic torque after simultanous shorts in both sides of a double-winding AC-DC generator.The expression and simulations which are suitable for engineering applications were verified by circuit model simulations.The method can also be used to analyze electromagnetic torques in double-winding AC-DC generators after shorts or just DC side. |
