EX21OOe励磁系统故障诊断与预警优化

励磁系统的运行与发电机及电力系统稳定性息息相关。EX2100e系统是目前GE公司燃气轮机的主 流励磁 系统，该系统 、输出信息少，与国产励磁系统差异较大，不利于运行维护人员及时发现并处理故障。针对这种 ，对该系统的保护、故障报警进行了分析梳理，并实施了故障 化方案，提升了系统 靠性。

EX21OOe Excitation System Fault Diagnosis and Early Warning Optimization

The operation of excitation system is closely related to the stability of generator and power system. EX2100e system is the mainstream excitation control system of GE company at present. The system has high degree of encapsulation, less alarm information, and is greatly different from other excitation system, which is not conducive to the timely detection and treatment of faults by operation and maintenance personnel. In view of this situation, the protection logic and fault alarm of the system were analyzed and sorted out, and the fault alarm optimization scheme was implemented, which improved the reliability of the system.
