| 摘 要： | 快速解耦法具有程序设计简单、计算速度快、内存占用量小、收敛性好等优点,因此成为高电压等级网络优先采用的潮流计算方法。但对一些病态系统,往往会出现计算过程振荡甚至不收敛的现象。在快速解耦法中引入最优乘子调节变量的修正步长,应用到交直流混合系统的潮流计算中,提高了计算速度,并有效地解决了病态交直流混合系统的潮流计算问题。通过算例验证了该方法的有效性。

| Abstract: | Fast decoupled method has many advantages such as simple program composition,fast computation speed,less memory requirement and good convergence.So it is used for load flow calculations of high-voltage networks as a priority.But for some ill-conditioned power systems,the calculation may be oscillatory,and even to be divergent.In this paper,optimal multiplier is introduced in fast decoupled method to adjust the amendment step of parameters.Fast decoupled method with optimal multiplier is applied to the hybri... |
