摘要
变频交流发电系统在航空电源上越来越受到重视。发电机转速的变化带来了发电机参数的变化,对发电机调节技术带来了挑战,现有的适合恒频发电系统的调压技术不能满足变频发电系统的需要。本文将发电机电压、励磁电流、发电机频率和负载电流四个量作为反馈量,构成多环反馈,用于新型的混合励磁无刷交流发电系统中,分析了混合励磁无刷交流发电机的特性。对发电系统进行了变频调压实验,实验结果表明,设计的发电机调压器减小了动态调节时间,适合于变频交流发电系统。
Aeronautic variable frequency（VF） AC generation system has been paid more and more attention.The variation of the generator characters keeps along with the variation of generator speed,and brings challenge to the voltage regulator,because the exiting technology of the voltage regulator can not fit the VFAC generation system.In this paper,the multi-loop feedback control technology is proposed.The four parameters including generator voltage,magnetic field exciting current,voltage frequency,and load current are detected and feedback to form the multi-loop.The generation system also contains the hybrid excitation synchronous generator（HESG）,which is a novel aeronautic brushless generator.The output characteristics of the HESG are also analyzed in detail.The experiment results verify the theoretic analysis and simulation.
