| Abstract: | A transformation was cult, the relay protection for booster made at booster fans frequency conversion in 2008. Because of the change of primary cir- fans and the primary system is recongfigurated. The relay for Booster Fan running at 50 HZ or changed frequency is discussed and the program about relay protection is presented. The relay protection＇s congfigura tion with CT and with the relay protection device at present was soluted, which ensures all the demands of relay protection. |
