摘　　要：现行技术在电力配电线路节能降耗中效果不佳,不仅线损率较高,而且线路电能损耗较大,无法达到预期的节能降耗效果。为此,开展基于自动无功补偿技术的电力配电线路节能降损研究。在配电端引入无功补偿器,自动采集配电线路电流与电压有效数据,预测配电线路负荷,根据配电线路负荷确定线路无功损耗,作为无功补偿器输出信号,自动调整其线路无功输出,以最小化无功损耗,实现基于自动无功补偿技术的电力配电线路节能降损。经实验证明,设计技术应用下配电线损率不超过2%,线路电能损耗得到了有效降低,节能降耗效果良好。The poor effect of current technology in energy saving and consumption reduction of power distribution lines,not only the line loss rate is relatively high,but also the line power loss is relatively large,which can not achieve the expected energy saving and consumption reduction effect.Therefore,this paper conducted research on energy saving and loss reduction of power distribution lines based on automatic reactive power compensation technology.The reactive power compensator is introduced into the distribution terminal to automatically collect the effective data of current and voltage of the distribution line,predict the load of the distribution line,determine the reactive power loss according to the load of the distribution line as the output signal of the reactive power compensator,and automatically adjust its reactive power output to minimize the reactive power loss,so as to realize the energy saving and loss reduction of the power distribution line based on the automatic reactive power compensation technology.Experiments show that the loss rate of distribution line is less than 2%under the application of design technology,and the power loss of line is effectively reduced,with good energy saving and consumption reduction effect.
