摘 要: | PSD-SCCP与PSASP是目前国内常用的2种短路电流计算软件,采用不同的计算条件及计算方法,计算结果将大不相同,已影响电网的决策。结合现行常用的3种短路电流计算标准,分析了不同标准对短路电流计算影响因素的处理差异,结合等效电路研究了线路和变压器电阻、线路电容、无功补偿、静态负荷对短路电流计算结果的影响。以"十三·五"期间某年江苏电网规划数据为基础,基于PSD-SCCP与PSASP 2种软件采用了6种不同的短路电流计算方法进行计算,并对计算结果进行比较与分析,提出了推荐意见,以期为电网规划和工程前期设计中短路电流计算提供合理的参考和思路。

Abstract: | PSD-CCP and PSASP are two commonly used software for short-circuit current calculation at present in domestic,however,the calculation results differs under different calculation conditions,affecting power grid planning and decision-making.With consideration of three standards for short-circuit current calculation,differences between them are analyzed,then some factors such as line and transformer resistances,line capacitors,reactive power compensation and static load affecting short-circuit current calculation results are analyzed theoretically combined with the equivalent circuit.Finally,six different short-circuit current calculation methods are adopted based on PSD-SCCP and PSASP using Jiangsu power grid planning architecture in some year during 2016-2020 as an example,and recommendations are put forward through comparing the calculation results,in order to provide reasonable reference and ideas for short-circuit current calculation in power grid planning and the early stage of project design. |
