摘　　要：串联补偿技术作为新兴发展起来的技术在配电线路上开始推广应用,配电网串联补偿技术能够改善辐射状配电线路沿线电压分布,有效减小线路损耗。通过数学模型对串联补偿技术的节能原理进行定量分析,推导出固定串联补偿节约有功功率和无功功率的量化公式。以理论分析为基础,结合运行数据,研究了串联补偿安装位置、串联补偿度及线路负载率对串联补偿技术节能效果的影响。结果表明,上述指标能有效评估配电网串联补偿的节能效果,对配电网节能降损工作有参考意义。Series compensation technology as a newly developed technology in the distribution lines began to promote its application. Series compensation technology in distribution network can improve the voltage distribution along the radial distribution lines and reduce the line loss effectively. The mathematical model was used to quantitatively analyze the energy saving principle of the series compensation technology, and the quantitative formula of the active power and the reactive power saved by the fixed series compensation was deduced. Then, based on theoretical analysis and operation data, the effect of installation position of series compensation, the level of series compensation and the rate of line load on the energy saving of series compensation technology was studied. The resuhs show that the above-mentioned indexes can effectively evaluate the energy saving effect of the series compensation of the distribution network, and have significance for energy-saving and loss reducing distribution network.
