摘　　要：针对具有特殊定子绕组结构的高低压双绕组感应发电机,提出计及定子双绕组间漏磁耦合的稳态分析模型。考虑定子2套绕组间的互漏感列写支路电压方程,引入流控电压源表示互漏电势,推导出双绕组感应发电机的稳态等值电路。通过计算流控电压源的复数控制系数,说明了稳态分析时计及定子双绕组间漏磁耦合的合理性。基于等值电路采用回路电流法列写矩阵方程,以回路阻抗矩阵的行列式绝对值为目标函数采用优化法进行求解,可以确定模型中的未知量。采用所建模型计算样机外特性和稳压电容值,计算结果与实验结果高度吻合,验证了所建稳态分析模型的正确性与准确度。For high-low voltage dual-winding induction generator with special stator-winding structure,the steady-state analysis model was proposed taking the magnetic leakage flux coupling between two sets of stator windings into account.Considering the mutual leakage inductance between two sets of stator windings,the branch voltage equation was formulated,and the steady-state equivalent circuit of high-low voltage dual stator-winding induction generator was derived where the current-controlled voltage source was introduced to express the mutual leakage electromotive force.By calculating the complex control coefficient of the current-controlled voltage source,the rationality of considering the magnetic leakage flux coupling between two sets of stator windings was explained.The loop current method was used to formulate the matrix equations of the equivalent circuit,and the optimization method was used to determine the unknowns of the analysis model taking the determinant of the loop impedance matrix as the objective function.The proposed model was used to calculate the output characteristic and the capacitance for voltage stabilization of the prototype.The calculation results are highly in agreement with the experimental results,which verify the correctness and accuracy of the proposed model.
