摘要
当具有随机相角的非线性负荷投入系统运行时，应考虑谐波叠加的问题。本文在一定的假设条件下，应用超值概率叠加方法计算出了同阶但有随机相角的谐波过限的概率。同时为了求解系统谐波畸变的水平，本文导出了一种更为直观的叠加方法──ＭｏｎｔｅＣａｒｌｏ模拟法。通过多次抽样试验，证明它可获得较为满意的谐波估计量。
When nonlinear loads are put into oper-ation at random phase angle in power system,the su-perposition of harmonics should be considered.In thispaper,under certain assumptiOns,the probability ofover-limit Harmonics which are or the same order andat random phase angles is obtained by means of super-position. Amore intuitive method of finding the de-gree of distortion caused by harmonics with the appli-cation of Monte-Carlo simulation is derived.By re-peated sampling test,it was proved that the harmonicsestimation was satisfactory.
