摘　　要：为了实现发电机定子单相接地多回路仿真模型的编程应用,利用修正的Calahan算法计算数学模型中的刚性状态方程。针对模型中时变电感矩阵难以求解的问题,结合运用MATLAB三维矩阵思想,运用修正的Calahan算法对单个时间点进行运算加以解决。用该方法编程分别对一台12kW同步发电机进行空载接地仿真,对一台30kVA凸极同步发电机进行并网单相接地编程仿真。仿真结果与试验数据对比结果表明采用该方法对仿真模型编程实现是可行的,从而方便了多回路仿真模型在本研究领域的应用。In order to apply the Multi-loop simulation model of generator stator single-phase grounding fault in MATLAB,modified Calahan algorithm is used in this paper.the means of Three-dimensional Matrix is used to solve the question that time-variable inductance matrix is hard to caculated;By the method,the stator single-phase grounding faults in a 12 kW synchronous generators without load and in a 30 kVA generator connected with power network are simulated,comparing the simulation result with the experiment data shows the method is feasible.Therefore the multi-loop model is more convenient for the study in this field.
