A single shaft coupled double-aerogenerator comprises a tower(6),a main machine frame(1),a main shaft(2),a wheel hub(3),a current transformer(5) and two aerogenerators(4),in which the middle of the main machine frame is connected with the tower securely, the main shaft is connected with the wheel hub and fixed on the main machine frame by a main bearing(21).The two aerogenerators are mainly provided with an inner stator(41) and an outer rotor(42) and fixed on the two ends of the main machine frame by the stator. The rotors of the two aerogenerators are connected with the main shaft. The stator side of each aerogenerator is connected with one or more independent full power current transformers that is parallel connection together and connected with an electric network. The single shaft coupled double-aerogenerator adopts a structure design of an outer rotor and an inner stator so having a compact structure, adopts a design of two generators thereby being capable of balancing the carrying capability of the generator bracing frame and helpful in prolonging the service lifetime of the generator tower, and applicable to the large generator system thus overcoming the defects of the current outer rotor aerogenerator. |
