摘　　要：介绍了对发电机励磁系统进行实时监测的一种技术方案。提出在复杂的电磁环境中使用光变送器测量励磁直流电流和励磁直流电压,从而提高数据采集的安全性、精确性和实时性;进而通过励磁系统仿真软件分析机组励磁试验的录波文件,实现静态自并励机组励磁参数识别。实验室录波数据和现场录波数据的分析结果表明了该方案的正确性。A technical solution on real-time monitoring of generator excitation system is introduced. In the solution, optical transducer measuring field current and voltage is used in complex electromagnetic environments in order to enhance the safety, accuracy and real-time of data collection. Through the simulation software for excitation system, recorded wave forms on unit excitation tests are analyzed and the excitation parameters of the static self-excitation unit are identified. The analysis of recorded wave data from the laboratory and field indicates the validity of the solution approach.
