灯泡贯流式水电站励磁系统改造探讨

Research on improvement of bulb flow through type hydropower station excitation system

潇湘水电站励磁系统于2002年5月随潇湘#1机组投入运行,在后期运行中,其调节性能和工作稳定性逐渐变差,为适应电力系统的发展趋势和提高企业的经济效益,潇湘水电站分别对2台机组的励磁系统进行了全面改造,改造效果良好。通过对励磁系统存在问题、技术改造方案及改造结果的深入分析和比较,总结了改造经验,指出了励磁系统在改造后仍然存在的一些问题并给出了相应的处理意见。

Xiaoxiang hydropower station excitation system was put into operation in May 2002 with No. 1 unit run. With the time going, its control performance and stable became worse. In order to keep speed with the power system development tendency and improve economical benefit, the comprehensive transformation scheme to 2 units was carried out, and the results were satisfied. By analysis and comparison of present problems, technical transformation schemes and transformation results, the transformation experience was summarized. The remained problems after excitation system transformation was pointed and relevant advice was presented.
