摘要
同步电机模型对电力系统稳定分析具有重要的影响。分析了同步电机三相短路的物理过程 ,推导了 5种形式的发电机模型 ,并指出两者间的联系。通过算例验证 ,在电力系统进行计算时应该根据实际要求 ,合理选择发电机的模型 ,否则各种模型计算的结果会有一定的差别。
Synchronous generator model has critical effect on power system stability analysis. The physical process of three phase short circuit accident of synchronous generator was analyzed and five types of synchronous models were deducted.The relationship between the process of three phase short circuit and the five models was indicated.It was suggested through computation examples that the synchronous generator model must be carefully selected according to actual request,otherwise the computations of different models may be different.
