某项目35 kV、多路10 kV不同电压等级进线供电方案比较分析

Comparison and Analysis on Power Supply Schemes of 35 kV,Multiple 10 kV Incoming Lines of Different Voltage Levels

以天津河西区马场道东侧地块项目为例,探讨了不同电压等级电源进线方式的供电方案,通过比较得出了各种方案的优缺点,提出在不考虑进线工程费及供电配套费前提下,从技术性、经济性及灵活性方面选择最优方案,可为类似项目供电方案设计提供参考。

Taking the east plot project of Machang road in Hexi District of Tianjin as an example,the power supply schemes of different voltage level power supply incoming lines were discussed.Through comparison,the advantages and disadvantages of various schemes were obtained.Without considering the incoming line engineering cost and power supply supporting cost,the scheme is considered to be the optimal scheme based on the principles of technicality,economy and flexibility.It can provide references for similar project design.
