潮流我已经计算过了，计算的结果放在ieee90.bse中

N-1的控制语句如下

(POWERFLOW,CASEID=004BPA,PROJECT=004BPA)
/OUTAGE_SIM\
>OLD_BASE,FILE=ieee90.bse<
>OUTAGE,BASE=110<
>OVERLOAD,BASE=110<
>OUTPUT_SORT,BOTH<
>DEFAULT_RATING<
110.       100.
100.       500.
(END)

计算的结果如下：

我想问为什么会有FATAL，还有怎么没结果显示啊？难道是我的控制语句写得不对？我在网上找了好久都没有介绍怎么算断线故障的，还请大神给我指点一下。

我说一下我遇到过的情况。没有加“>DEFAULT_RATING<”语句，但是在潮流数据文件dat中，每条线路参数都设置了额定电流值。但是一开始设置的数值都很小，潮流dat文件可以运行，但是N-1的dat文件报错如楼主所说。在修改了各条线路的额定电流参数后，N-1校验dat文件可以正常运行，并显示电压越限节点和过负荷线路情况。

注释掉就可以了吧。

很少有人用BPA算N-1吗？

geytao · 发表于 2011-8-30 14:33:02

算N-1，是SWI程序吧？

你是指用稳定来计算？

是吧？

joeyuan · 发表于 2011-9-12 00:32:57

胡扯，BPA的N-1断线校验是属于热稳定问题，和暂态稳定计算没关系，不涉及swi卡。

看看BPA的说明书吧，貌似没什么问题。

很可能是你目标文件路径里有“桌面”这样的中文引起的错误。

直接把线路注释掉就可以了啊

在不含中文的目录中运行也是一样的错误
