新手求助配电网潮流分析

shirleyy

请问下配电网基本的分析软件常用的有哪些？计算潮流，短路故障等，我查到的有opendss，pss/adept等，不知道是不是可以直接应用

! e. E; m& c: V$ x因为后期要与matlab接口，担心这些软件接口不好做，我目前想直接用matlab编程来计算配网潮流，用前推回代法，目前只编写了一个辐射配网的程序，无环网，无分布式电源，还比较简单，后期加如这些的话不知道实现起来难度大不大

6 j4 g) h1 L5 s/ T3 Y我是新手，怕走弯路，想听听大家的建议


2 I, o! O! V- R& n拜谢大家

唉，没人回答，自言自语吧
$ L. e! H! [7 ]$ u我用matlab编写的基于功率来前推回代的程序，算出来和别人的基于电流前推回代的程序总是差那么一点，小数点后一位基本相同，后面就不同了，检查了半天也没看出有什么错误，不知道会不会因为算法不同呢

use MATPOWER for load flow analysis

It's free and easy to use. All you need is your distribution network data.

算输电网的倒是很多软件。。。

Distribution company in Australia uses PSSE for modelling their network at voltage level 132kV, 66kV, 33kV, 11kV and alike.

Notice MATPOWER has limited modelling capability and doesn't have a user friendly interface. MATPOWER is a good tool for academic purpose and it's free.

    没太明白你说的，配网和大网的结构，r、x比值不一样，算法上用大网的有时不收敛啊

X/R ratio is already considered in the model. What do you mean by "不收敛"???

As far as I know, the distribution utility here in Australia uses PSSE for their network.
