Abstract
As the demand for distributed power supply increases, the permanent magnet generator with many advantages has been widely used. In order to overcome the defect that the permanent magnet generator can't maintain the output voltage constantly by adjusting the excitation current the same as with the electrically excited synchronous generator, this paper presents the stabilized control strategy based on speed-adjusting of prime mover, that is use the rectified DC voltage as feedback through adjusting the speed of the prime mover to achieve no static error control. This paper introduces the control principle of the power generation technology, based on the research of the external characteristics of permanent magnet generator and operating characteristics of the prime mover analysis of the feasibility of this control method. The curve of the prime mover's speed varies with load obtained by co-simulation when maintaining the generator's output voltage constantly. The control strategy proposed in this paper is the organic combination of the prime mover and generator, which simplifies the control the structure of generator set. This power generation technology is suitable for the distributed power supply spontaneous for personal use. The stabilization of DC voltage can avoid the requirement of constant frequency and the stable DC power supply can supply the power for DC load or through the inverter for AC load.
