辐射配网潮流技术在环网中的应用

根据牛顿法的基本原理，建立了一种基于辐射配网潮流技术的求解有环配电网潮流的新模型，该模型对配网中每条支路引入一对变量，使得到的功率方程变为严格的线性方程，同时在环网部分加入反映状态变量关系的环网方程，形成了适用于有环配电网的潮流技术，提高了这种潮流技术的实用性．文章的最后，以多个算例对该方法进行了验算，并与传统牛顿法做了比较，结果表明，这种方法具有良好的收敛性能，且在收敛速度上明显优于牛顿法。

Reliable Power Flow Technique for Meshed Distribution Networks

According to Newton-Raphson(NR) method, a new power flow method based on reliable power flow technique is proposed.By introducing a pair of variables to each branch, the power equations of radial distribution networks become linear. By adding equations that reflect the relation of state variables, the power flow technique that is suitable for meshed distribution systems is formed and the practicability of the technique is enhanced greatly. The proposed method has been applied to several meshed distribution networks and the results show that our method is superior to conventional NR method both in terms of speed of convergence and computation times.
