摘要：本文从双Y相移30°同步发电机的电磁和机械关系出发，推导出理想双Y同步发电机数学模型，并建立了脉冲方式运行且输出频率变化情况下的隐极式双Y移30°同步发电机Simulink仿真模型.进而对双Y相移30°同步发电机依靠轴系释能机械能通过不可控整流为感性负载供电的过程进行了仿真。通过与80MVA隐极式双Y移30°同步发电机实际运行结果对比分析，证实了仿真模型的可靠性和合理性。

Abstract: According to the electro-magnetic and mechanical relationships in double Y six-phase synchronous generator with cylinder rotor, based on ideal assumption terms, a mathematical model of six-phase double Y synchronous generator was deduced, and then a simulation model for that type generator with its output frequency being able to change was established by using Simulink. Furthermore, the process of a 80 MVA dual Y shift 30° generator supplying an inductive load through diode rectifier only by releasing its mechanical energy stored in its shaft was simulated. Comparing the simulation results with the operation results of the real 80 MVA synchronous generator, it shows that simulation model has certain rationality and reliability.
