摘要
建立了同步发电机直接带整流负载的数学模型,通过对其运行状态的分析,推导了以换相重叠角为自变量的同步发电机—整流系统电流、电压谐波畸变计算公式。根据换相重叠角与发电机电磁参数的关联,确立了系统谐波特性与发电机电磁参数间的函数关系。分析了变压器对同步发电机—整流系统谐波特性的影响,利用仿真验证了发电机电磁参数、推进变压器对系统谐波畸变的影响规律,最后利用搭建的同步发电机-整流系统试验平台对部分仿真结果进行了验证。确定了适用于船舶综合电力推进系统的同步发电机的电磁参数设计方法。
A mathematics model for synchronous generator with rectifier was built up. By analyzing the operation of the system, the formulas of the harmonic distortion for synchronous generator-rectifier system current and voltage were supplied with the overlap angle as variable. Based on the connection between overlap angle and electromagnetism parameters, the function between the harmonic characteristics of the system and the electromagnetism parameters of the generator were brought forward. The influence of transformer on synchronous generator-rectifier system had got. The simulation validated the rule that influence of electromagnetism parameters and propulsion transformer on the harmonic distortion. Finally, some of the simulation result had got proved through a generator-rectifier system experimental platform. Make up a rule for three phase generator design for electromagnetism parameter used in integrated power system.
