【摘要】：計及新能源分布式電源(DG)并網(wǎng)對智能配電網(wǎng)的影響,構(gòu)建了一種含DG配電網(wǎng)的可延展通用模型。基于模型結(jié)構(gòu)等效變換,分析了引起電能質(zhì)量監(jiān)測儀方向誤判的影響因素,針對電壓暫降型或電壓暫升型的電能質(zhì)量(PQ)擾動源,提出了DG并網(wǎng)對PQ擾動方向判定的影響規(guī)律,進(jìn)而提出了一種基于規(guī)律校正的PQ擾動方向判定算法。將多個DG接入IEEE 13和IEEE 34模型,Matlab仿真表明,該算法能提高PQ擾動方向判定的準(zhǔn)確率,并具有簡明清晰、抗噪聲能力強(qiáng)等優(yōu)點。
[Abstract]:Considering the influence of new energy distributed generation (DG) on smart distribution network, a general extensible model with DG is constructed. Based on the equivalent transformation of the model structure, this paper analyzes the influencing factors that cause the misjudgment of the direction of the power quality monitor. In view of the power quality disturbance sources of voltage sag or voltage surge, the influence of DG grid connection on the determination of the PQ disturbance direction is put forward. Furthermore, a PQ disturbance direction decision algorithm based on law correction is proposed. The simulation results of IEEE 13 and IEEE 34 model show that the algorithm can improve the accuracy of PQ disturbance direction determination, and has the advantages of simplicity and clarity, strong anti-noise ability and so on.
