摘要
结合大型水电厂仿真培训系统中对水轮发电机内部故障仿真的需要 ,根据交流电机的多回路理论 ,在相坐标系a ,b ,c中建成立了多支路凸极同步电机以定子一条并联支路为基本单元的数学模型 。
For the sake of synchrogenerators simulation, a different method in calculating internal fault currents in salient pole synchrogenerators under the unsymmetrical conditions is advanced. Based on the multi-loop theory for alternative generators a generator is considered as a circuit in which there are many electric branches Each branch is composed of many windings, and each phase is composed of a few branches This method can be used to analyze and calculate fault currents when both internal and external faulties occur at the breakdown of synchrogenerators
