摘要
为研究110 kV架空线单相断线接地时的短路电流,以线路和变压器的实际参数为基础,分别建立了ATP-EMTP仿真模型和理论计算模型。理论计算结果与仿真结果吻合,表明了仿真结果的正确性。研究结果表明架空线负荷侧单相断线接地时的短路电流较小,可为线路单相断线接地时的应急调度提供理论支撑。
In order to study the short-circuit current of single-phase broken and grounding fault of 110 kV overhead line, the ATP-EMTP simulation model and theory calculation model are built based on the actual parameters of line and transformers. The simulation results are consistent with theoretical results, which shows the validity of simulation. The results show that the short-circuit current is small when overhead line is broken and grounded, which can provide theoretical support for emergency dispatch.
