350MW机组发变组保护双重化改造

350MW Generator Transformer Group Protection Modification

根据继电保护双重化配置的要求,许昌龙岗发电有限责任公司对#1、#2号发变组保护进行双重化配置改造。每台机组设置三面电气保护柜,其中A、B柜为电气量保护柜,C柜为非电量保护柜,保护动作于跳闸或信号。对汽轮机联跳发电机、发变组联跳汽轮机逻辑进行修改,并做了详细说明。保护改造至今,机组运行安全可靠。

According to the double configuration of relay protection requirements,Xuchang Longgang power generation limited liability company on1,2 aircrew generator-transformer group protection for double configuration transformation.Each unit setting three cabinet, wherein A,B cabinets for electrical protection cabinet,can realize the generator-transformer group all the electricity protection,C cabinet for non-electricity protection cabinet,can realize the generator-transformer group all the non electrical quantity protection.Protective action on the trip or send a signal.On turbine tripping generator, generator-transformer unit combination jump turbine logic modification, and a detailed description.Unit 1reforming so far,generator-transformer group protection and safe and reliable operation,various parameters showed normal.
