摘要:
  为了更准确分析发电机非全相定子电流特性,建立了适用于发电机并网运行的基于调速控制的场-路-网耦合时步有限元模型,仿真计算了发电机并网额定运行时,接线方式为YNd11 变压器高压侧断路器一相或两相断开2 种非全相工况下的定子电流,揭示了不同非全相情况下定子各相电流之间关系,分析了转速控制对故障电流动态影响,并计算2 种故障后定子稳态负序电流,整个仿真计算结果考虑了发电机故障运行时,发电机磁场饱和、畸变等非线性因素的影响,同时为了模拟真实的发电机的并网运行情况,整个场路耦合模型中包含了转速控制系统,并且通过变压器、双回架空输电线路将发电机与无穷大电网连接起来,这样更能贴近工程实际,最后,将结果与解析法得到的结果进行对比,验证了方法的正确性。
Abstract:
 In order to accurately analyze the stator current of the generator under open-phase condition,the field-circuit-network model with the speed control suitable for the generator running under grid connected condition is established. The stator current was calculated under two kinds of open-phase conditions.The one phase or two phases of the YNd11 transformations high voltage( HV) side were off,when the generator was running at rated grid connection connected condition. The relationship between the stator currents was revealed under different phase-open conditions. Also the dynamic influence of the speedcontrol on the fault current was presented. The steady negative-sequence current was calculated under two kinds of fault conditions. The influence of nonlinear factors on the simulation results was considered under open-phase condition. In order to simulate the generator running at grid-connected condition,the fieldcircuit-network model contained the speed control system,and the generator and the infinite system were connected by the transformer and parallel two-way overhead power transmission lines,which was closer to the engineering practice. Compared with the result of analytical method,the validity of the method is proved.
