110 kV变电站电气设计

Electrical Design of 110 kV Substation

文章通过对负荷资料的分析和计算,根据结果确定变电站主变压器台数、容量以及型号,从安全、经济及可靠性等方面考虑,设计出110kV、35kV及10kV电压等级的主接线方案,并根据系统阻抗计算出短路电流大小,为后续高压电器设备的选型提供依据。

Based on the analysis and calculation of load data,the number,capacity and type of main transformer in substation were determined according to the results.Considering safety,economy and reliability,the main connection schemes of 110 kV,35 kV and 10 kV voltage levels were designed.The short-circuit current was calculated according to system impedance.A basis for the selection of subsequent high-voltage electrical equipment was provided.
