电力系统谐波潮流的一种解耦算法

从电力系统谐波潮流计算的线性算法和非线性算法出发，提出了谐波潮流的一种解耦算法，改变常规非线性算法中将基波潮流与谐波潮流联立迭代的方法，使两者分立求解。其中，基波潮流通过牛顿法迭代求解，谐波潮流通过高斯消元法求解，两者通过功率方程关联，并以此考虑基波与谐波之间的相互影响。文中给出了该解耦算法的原理，程序框图和实际算例。计算表明，该算法具有较高的计算精度，同时明显减少了计算量，节省了内存，提高了计算速度，收敛可靠。

A DECOUPLED ALGORITHM FOR POWER SYSTEM HARMONIC FLOWS

On the basis of the linear harmonic flowalgorithms and the nonlinear harmonic flow algorithms adecoupled harmonic flow algorithm is given, in which thesimultaneous iteration of fundamental power flow withharmonic flows in conventional non-linear algorithms ischanged into separated iteration. The fundamental power flow is iterated and solved by Newrton method and the harmonic flows are solved by Gauss elimination. The two methods are incident with one another by power equations and theinteraction between the fundamental and the harmonics isaccordingly considered. Using this algorithm the calculation accuracy is improved and the amount of calculation is greatly reduced. Meanwhile, the memory is saved, the calculation is speeded up and the convergence is reliable. The principle, flow chart of this algorithm and practical calculation examples are given.
