摘要
利用建立在对称分量解耦-补偿理论基础上的电力元件模型,提出了适用于谐波潮流计算的网络模型和算法。该算法计及低次谐波潮流对基波潮流的影响,而忽略高次谐波的影响;然后与性能良好的PQ解耦法结合,形成了实用的电力系统三相谐波潮流计算程序。由于潮流可按正序、负序、零序分别求解,在保证求解精度前提下,提高了求解效率。
By using the power element models established on symmetrical component decoupling - compensation theory ,a network model with algorithm suitable for harmonic flow calculation is deve - loped.It calculates the effect of low - order harmonic power flow on fundamental power flow and ignores that of high - order harmonics.Incorporating with the conventional P-Q decoupling load flow algorithm ,a practical three - phase harmonic flow program is brought up.The harmonic flow study can be undertaken in positive -,negative - and zero - sequence reference frames separately ,thus the computation efficiency can be enhanced with acceptable precision.
