龙羊峡电厂的励磁调节器由于设计、制造、安装等方面的原因,自87年第一台机投产发电以来,励磁调节器的问题一直较多,多次造成机组事故停机,严重威胁着我厂机组的安全运行,为此决定对设备进行技术改造。在充分调研的基础上,采用了南京电力部电力自动化研究院电气控制公司生产的 SJ—820型双微机励磁调节器来更换原调节器。第一套新调节器于1992年7月在我厂四号机上投运,取得了明显的效果。机组安全运行水平得到了大幅度提高。
Longyangxia Power Plant’s excitation regulator due to design, manufacture, installation and other reasons, since 87 the first machine put into operation since the excitation regulator has been more problems, causing multiple crew downtime, a serious threat to me The safe operation of the plant unit, to this end decided to carry out technological transformation of the equipment. On the basis of full investigation, the SJ-820 dual microcomputer excitation regulator manufactured by Electric Control Company of Nanjing Institute of Electric Power Automation was used to replace the original regulator. The first set of new regulators in July 1992 in our plant on the fourth machine put into operation, and achieved remarkable results. The safe operation of the unit has been greatly improved.
