Analysis of dynamic processes for turbo-generator

针对目前汽轮发电机失磁异步运行性能的不断提高,对汽轮发电机失磁过程进行了仿真分析。从系统角度建立了模拟汽轮发电机失磁故障的数学模型,并利用Matlab/Simulink对失磁全过程进行了仿真分析,并利用该模型对汽轮发电机的失磁故障进行了仿真计算。仿真结果与实测结果的对比说明了仿真模型的正确性,对电机设计和电网运行具有一定的有参考价值。

Aiming at improving of asynchronous operation lost magnetization on turbo-genrator, the dynamic process of the turbogenerator under excitation loss was analyzed. At first, the excitation-loss model was estabished, and the whole process under excitation loss with Matlab/Simulink was simulated. The excitation loss of the turbo-generator was simulated. It illustrates the correctness of the model by comparing the simulation result with the measured result. The result is valuable to design generator and operate the power grid.
