摘　　要：混合励磁发电机具有较宽的电压调节能力,可实现发电机变速稳压输出,但负载发生突变时,发电机的稳压能力会受到影响。文章的研究对象是一种宽转速的混合励磁发电机,针对负载发生突变的工况下发电机输出电压出现大幅度下降的故障进行研究和分析,提出了改进方案并进行试验验证,试验结果显示改进方案解决了负载突变时输出电压出现大幅度下降的瞬变故障,为该类问题提供了一种解决思路。The hybrid excitation generator has a wide voltage regulation ability,which can realize the variable-speed and stable output of the generator.However,when the load changes suddenly,the voltage-stabilizing ability of the generator will be affected.The research object of this paper is a wide-speed hybrid excitation generator.The failure of the generator output voltage to drop significantly under the condition of sudden change of load was studied and analyzed,and an improvement plan was proposed and verified by experiments.The test results showed that The improved scheme solved the transient fault that the output voltage drops sharply when the load suddenly changes,and provided a solution to this type of problem.
