利用相似模型类推法对蒲城电厂 1号、2号机组励磁机与发电机连接短轴断裂进行了分析 ,论证了在电网故障冲击下励磁机与发电机连接短轴安全裕度不足 ,是该型机组短轴断裂的主要原因
The similar model analogy was used to analyze the short-axis faults of exciter and generator connections in Pucheng Power Plant No.1 and No.2 units. It is proved that the safety margin of the short-axis between the exciter and the generator is not enough under the fault of the power grid. The main reason for the short axis fracture of the unit
