EX2000励磁系统国产化改造及应用

EX2000 Exciter Localization Retrofitting and Application

叙述了9E燃机EX2000励磁系统国产化改造项目背景和主要工作内容,通过试验研究破解9E燃机励磁系统的控制策略,成功地用国产RCS-9400微机型励磁调节器替代进口EX2000励磁调节器,并完成了励磁系统模型参数测辨和电力系统稳定器整定试验,建立了可反映强励、限幅、PID和电力系统稳定器特性的RCS-9400励磁系统模型。

The paper illustrates the background of the EX2000 exciter’s localization retrofitting for 9E gas-turbine.The major work includes the followings：analyzing the control strategy of the 9E GT s exciting system,replacing the EX2000 exciter with the home-made exciter（Type RCS-9400）,completing the exciter s model parameters measurement and the PSS test.A detailed model of RCS-9400 exciter is set up,which reflects forced excitation,limited range,PID and the characteristic of PSS.
