【摘要】：針對低壓配電網(wǎng)日益嚴重的電能質量問題,在配電變壓器低壓側加裝一定容量的綜合補償裝置對諧波、無功及三相不平衡進行集中綜合治理與補償。由于補償裝置容量受限,為了提高綜合補償裝置的補償容量利用率,在此提出了一種將電能質量綜合評估方法與傳統(tǒng)實時檢測控制方法相結合的綜合補償控制策略。該策略運用電能質量綜合評估方法量化電能質量指標,以反映電能質量情況,使綜合補償裝置周期性調整各補償量的補償比例,更合理利用補償容量。最后,通過仿真及實驗驗證了所提綜合補償控制策略的優(yōu)越性。
[Abstract]:In view of the increasingly serious power quality problem in the low voltage distribution network, the harmonic, reactive power and three phase unbalance are comprehensively treated and compensated by adding a certain capacity comprehensive compensation device to the low voltage side of the distribution transformer. Because of the limited capacity of the compensator, in order to improve the utilization ratio of the compensation capacity of the integrated compensator, a comprehensive compensation control strategy combining the power quality comprehensive evaluation method with the traditional real-time detection control method is proposed. In order to reflect the situation of power quality, the comprehensive power quality evaluation method is used to quantify the power quality index, so that the compensation ratio of each compensation quantity is adjusted periodically and the compensation capacity is used more reasonably. Finally, the superiority of the proposed comprehensive compensation control strategy is verified by simulation and experiments.
