摘要
本文首先提出一种分析运动磁场模型的有限元剖分方法,通过三相凸极同步发电机空载电压谐波计算证明了该剖分方法的简便性和实用性。然后阐述了电路和运动磁场间耦合关系的处理方法,从而使瞬变磁场计算和电路动特性仿真同时得解。文中给出同步发电机三相突然空载短路的例证。
A new method for subdivsion of finite element mesh in the analysis of a moving field model is first developed. Its convenience and availability was proved through the computation of no-load voltage harmonics for 3-phase salientpole synchronous generator. The treatment of the relationship between the electric circuit and its coupling moving field is then discussed, which makes the simultaneous solution of the transient field calculation and the dynamic characteristic of electric circuit to be available. An analysis of the 3-phase sudden short-circuit of a salientpole synchronous generator is shown in this paper as a practical example.
