Simulation Analysis on Loss of Excitation Phenomenon for Synchronous Generator

文章介绍了同步发电机失磁现象,并分析了失磁产生的原因及其危害。以一台8极同步发电机为例,通过有限元软件模拟仿真,对突然发生不同程度失磁故障的发电机电流、电压等物理量进行了仿真分析。

The loss of excitation phenomenon of synchronous generator is introduced in this paper,while the causes and harms of loss of excitation are analyzed.Taking an 8-pole synchronous generator as an example,the physical quantities such as current and voltage of the generator under the condition that different degrees of sudden loss of excitation fault occur are simulated and analyzed through the finite element software simulation.
