Parameter Calculation of Three Parallel-circuit Winding Schemes of Large-size Generators

提出大型空冷汽轮发电机定子三支路绕组理论排列组合方案集的计算方法,并在数量巨大的可选方案中,提出相应的支路绕组分布系数和电动势不平衡度计算方法,为建立大型汽轮发电机三支路绕组设计方案集提供理论基础。

Calculation method of permutation and combination of the stator three parallel-circuits winding for large-size air-cooled turbine generator is presented.For hundreds of millions of schemes,the corresponding calculation methods of circuit winding distribution coefficient and electromotive force unbalance degree are proposed,to provide the theoretical basis for establishing a feasible three parallel-circuit winding design scheme for large-size turbine generators.
