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
/ O2 @1 n* n5 z  w7 K$ ]
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

唉，没人回答，自言自语吧
% e7 P" k9 N' H1 y2 W( K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

    I don't see a reason why you can't use it. The underline models of such algorithm are purely based on those described in the power system text books.

) B5 Z% E1 E9 R) @Some of the difference between distribution and transmission networks are:
- voltage level, line data, circuit configuration
- network topology
" W  _: s) B/ ]% S9 S - different protection setting

Distribution company in Australia uses PSSE for modelling their network at voltage level 132kV, 66kV, 33kV, 11kV and alike.
" q+ v: d2 z9 K" S( M3 kThe sole reason that you don't use simulation software for network modelling is when the network is radially connected (i.e. does not form a ring circuit at all). In such case, the calcualtion is rather straightforwad. They can be viewed as discrete branches.

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.

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