摘要:

目前实际生产中尚缺乏有关电力系统关键设备(变压器、断路器等)短路电流累积效应的计算方法。针对此现状，提出了一种基于PSD-BPA程序包的批处理计算方法。该方法依据实际故障发生时间、故障类型及系统运行方式，批量计算系统的故障短路电流累积效应。该计算模型已应用于江苏电网。最后，提出了在电力系统应用的图形化显示设想。根据各设备历史故障电流累积效应来排序，提供设备状况预警和设备检修优先策略，将有助于改善电网安全稳定运行状况。

Abstract:

There is no effective quantitative analysis method in the cumulative effect of the short circuit current which aims at key equipment (transformer, circuit breaker, etc.) in power systems. A fault short-circuit current cumulative effect analysis model based on PSD-BPA simulation procedures is presented for this condition. The model uses batch calculation for several short-circuit faults based on the fault occurrence time, the actual fault type and system operation mode. The paper presents the results of the cumulative effect of a fault in the Jiangsu power grid. Finally, it puts forward the ideas of the graphical display of application in power system. The proposed method can be used to sort the equipment according to the equipment history fault current cumulative effect, and provide early warning and maintenance of the equipment by priority strategy, which will help to improve the safe and stable operation of power grid.

Key words: cumulative effect analysis PSD-BPA batch operations graphical display of cumulative effect short-circuit current key equipment
