====================================================PART 8 IEEE39节点模型当年做毕设用了Norika版主在PSCAD上搭建的10机39节点系统，真是如鱼得水，感激涕零...现在在交流会上居然拿到了一个10机39节点的模型，自己也跑了一次，收敛。虽然说拿电磁暂态软件来做大系统的机电暂态不太方便，但是确实是可行的，所以也拿出来与大家交流，给大四做毕设的孩子们一点帮助。 WAYYAWWEN 发表于 2015-7-14 11:18
用最新版的PSCAD去运行IEEE39的文件，最后程序会异常终止，原件和模块都没有错误，请问这是什么原因
能否向你请教一下39节点模型
3球 特别好的分享 谢谢卤煮 恰好做次同步振荡方向 楼主你好 为什么我的新英格兰39节点没有运行结果 总是中断 新手 请求指导 lz,好像少上传一个Wind-Power-Case.rar附件。:sleepy: 回复 2# mingyu
补上了，帖子过了30分钟怎么改？ 楼主 能不能便宜点 Wind-Power-Case这个用哪个版本PSCAD能打开 这么贵啊 本帖最后由 sunek 于 2012-5-27 13:21 编辑

我是想把专家分都给去掉...改不了么..那个风电部分的复制上来的时候格式乱了，wind power case里面包含：
1.矢量控制的双馈异步风机（DFIG）模型和永磁直驱风机（PMSG）模型（适用于X4.4版）注：V4.2版本打不开.pscx文件（见附件Wind-Power-Case.rar中的DFIG_Case-X4.4）

6.风机（异步机）的过流保护模型（见附件Wind-Power-case.rar中的DGinterconnnectCase_01） 回复 6# mrqinhuai
不了解行情，过了30分钟不能编辑专家分去不掉么，只好求助版主了 建议版主加精啊 有点贵了……能便宜点吗？
