Abstract

The invention provides a variable-speed constant-voltage generator. The generator adopts fundamental wave and harmonic wave excitation. Firstly, stator and rotor cores are lengthened so that the generator can reach the rated power at relatively low rotating speed; through using the fundamental wave and harmonic wave excitation, when the rotating speed range of the generator is changed, the technical performance of the generator can be ensured at the changed rotating speed; a shaft is of alloy steel, the comprehensive mechanical property of the shaft is enhanced, when the rotating speed of the generator is changed, the motor shaft still can bear the rated load. The generator uses the excitation system which is good in performance and is composed of fundamental wave and harmonic wave coils and AVR; when designing the electromagnetism, main sizes and parameters are selected and determined rationally, and both technical performance and economic performance are taken into consideration when the rotating speed of the generator is changed.

Description

technical field [0001] The invention relates to a generator that outputs a constant voltage when the rotating speed (1350-1710r / min) range changes, and reaches rated power at a low rotating speed, and specifically relates to a variable-speed constant-voltage generator. Background technique [0002] Usually, when the generator is lower than the rated speed, the load capacity of the generator will decrease, and the voltage will also be unstable. When the speed of the diesel engine used by the user changes, the electrical components used for the load cannot work normally. And can utilize the excess power of the main diesel engine to drive the generator to generate electricity for the ship, so the operating efficiency of the main diesel engine can be improved, and the power consumption and cost of the auxiliary engine power system can be saved. Contents of the invention [0003] The purpose of the present invention is to provide a variable-speed constant-voltage generator. Th...
