Short circuit calculation and simulation of twelve phase rectifier synchronous generator

根据发电机定转子磁链、转速等状态量之间的耦合关系,建立了船用十二相整流同步发电机在旋转dq坐标系下的数学模型,并通过参数转化得到直流侧极间短路电流的解析计算公式,为直流侧短路故障的危害评估及保护研究提供了依据,仿真分析验证了该文理论分析和计算的正确性。

According to coupling relationship between stator and rotor flux linkage,speed and other state variables of generator.In this paper,mathematical model of marine twelve phase rectifier synchronous generator in rotating dq coordinate system is established,and the analytical calculation formula of DC side inter pole short-circuit current is obtained through parameter transformation,which provides a basis for hazard evaluation and protection research of DC side short-circuit fault.The simulation results show the validity of theoretical analysis.
