摘要
以山西阳光发电有限责任公司2008年对增压风机进行变频改造为例,由于一次回路的变化,对增压风机及一次回路进行保护重新配置,对变频及工频运行两种工况下的保护进行研究探讨,提出保护配置的方案,并解决现阶段电流互感器CT(Current Transformor)及保护装置实际运行工况下保护的配置。
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.
