220 kV变电站主接线的设计研究

摘要

The main electrical wiring of 220 kV substations has been designed. Based on the general power supply situation, load calcula-tion, reactive power compensation capacity and other factors, this paper analyzed the speciifc form of the wiring, the selection of main trans-former and gave the calculation of short-circuit current, electrical equipment and bus selection criteria. The results show that the design has high practicability in actual power transmission process.%对220kV变电站电气主接线进行了设计，基于一般供电情况、负荷计算和无功补偿容量等因素对具体的接线形式、主变压器选择进行了分析，并给出了短路电流计算及电气设备与母线选择标准。结果表明，该设计在实际输电过程中具有较高的实用性。
