变电站主变压器低压侧主回路与站用变压器回路共用间隔的布置优化研究

Study on the Layout Optimization in the Same Space Between the Low-voltage Side of the Main Transformer and the Auxiliary Transformer

针对变电站低压侧配电装置占地面积大、工程造价高等问题,以500 kV变电站为例,就变电站内主变压器低压侧站用变压器户外布置方案进行优化,采用主变压器低压侧主回路与站用变压器回路共用间隔的布置方案。对比分析相同电压等级变电站低压侧的常规布置方案与新型布置方案,得出新型优化布置方案,可大大节省主变低压侧占地面积,节约工程造价。

In view of the low-voltage side of transformer substation distribution equipment covers area is large,engineering cost is high.We take 500 kV substation as an example and do the research of the substation low-voltage side of transformer station transformer outdoor layout optimization.The layout optimization in the same space between the low-voltage side of the main transformer and auxiliary transformer is adopted.The low-voltage side of transformer substation based on the same voltage grade of general layout plan and the new layout of comparative analysis,concluded that the new optimal layout scheme can greatly save the floor area of the low voltage side and the project cost.
