3条进线3台变压器的110kV变电站主接线方式选择

Selection of Main Connection Methods for a 110kV Substation with Three Incoming lines and Three Transformers

国家电网公司"两型一化"变电站建设设计导则,对110kV终端变电站主接线方式提出了具体的要求。以一座典型3条进线3台主变压器的110kV变电站主接线方式的选择为例,通过分析国家电网公司通用变电站设计中的几种典型主接线方式的特点,对该典型110kV变电站主接线方式进行初步选择。经过方案比较,确定了适合3条进线3台主变压器的110kV变电站的主接线方式。

According to substation requirement are raised to the 110 construction guidance ＂two type one model＂ by kV terminal substation main connection methods. State Grid, specific A typical 110 kV substation with 3 incoming lines and three transformers set as an example, features of several classical main connection methods for designing of common substation within State Grid are analyzed and basic selection of the 110 kV substation main connections is settled. After comparing, a suitable main connection method is decided for the 110 kV substation with 3 incoming lines and three transformers.
