摘要
龙滩水电站分两期建设 ,电站水头变幅大 ,在不增加水轮机额定水头、额定出力和转轮直径的前提下 ,推荐机组最大容量为 70 0MW ,并采用不更换转轮和不改变机组转速的方案。同时推荐发电机电压母线选用离相封闭母线 ;主变压器采用特殊组合三相变压器 ;5 0 0kV高压引线选用干式电缆 ;5 0 0kV配电装置采用GIS。
The construction for Longtan porject is divided into two stages. Its water head fluctuation is big. Under the condition of no increase in normal head, normal output and runner diameter of turbine, it is recommended a max. capacity 700 MW without replacement of runner and unit speed. It is also recommended to use separate phase closed generator voltage bus bar; special composite three phase main transformer; dry cable for 500 kV high voltage lead; CIS for 500 kV distribution device.
