摘要:
为了研究船用发电机在稳定运行时,不同负载对发电机电磁振动大小的影响,首先通过理论分析阻性和感性负载下发电机内部合成磁场的变化规律,建立电磁振动响应模型,并运用Maxwell张量法推导出不同合成磁场下的电磁力波,然后用模态叠加法计算发电机定子的振动响应,最后通过ANSYS Electronics仿真与实验进行验证。结果表明,当永磁同步发电机负载为阻性负载时,随着有功功率的增加,发电机各点振动增强;负载为感性负载时,随着内功角的减小,发电机各点的电磁振动增强。
Abstract:
In order to reduce the vibration of marine generator,the influences of different loads on the electromagnetic vibration of Marine generators during stable operation are studied.In this study,author focuses on the influence of various types of load,which is under a high operated stability,on the electronic vibration.The electromagnetic vibration response model was established by theoretical analysis of the variation rule of the intemal synthetic magnetic field of the generator under the load of inductive or resistance.It theoretically analyses the changing regular of interal resultant field with resistor inductance load.Maxwell tensor method was applied to deduce electromagnetic waves under different synthetic magnetic fields,and modal superposition method was used to calculate the vibration response of generator stator.Maxwell tensor method is applied to deduce the magnetic waves under various resultant magnetic field.Besides,with mode superposition method,author computes the vibration response of generator stator.Finally verified by ANSYS Electronics simulation and experiment,the experimental results are consistent with theoretical analysis.The conclusion is that when the load is resistive,the vibration of the generator increases with the increase in active power.When the permanent magnet synchronous generator load is the resistive load,the electromagnetic vibration of each point of the generator increases with the Internal power angle ψ decrease.
