针对当前低压配电网线损率较高,影响配电网正常运行的问题,本文将开展低压配电网线损分析和降损措施研究。首先,对线损构成进行分析。其次,结合得到的分析结果,构建低压配电网线损计算神经网络模型。在明确造成低压配电网线损的具体原因后,提出无功控制、合理选择确定配电变压器能耗等级与布置位置、优化计量统计控制等降损措施。将本文所提出的降损措施应用于实际,低压配电网的网损率得到有效控制,同时此次研究也可以为相关工作的开展提供重要参考。

In response to the current high line loss rate in low-voltage distribution networks,which affects the normal operation of the distribution network,this article will conduct a study on line loss analysis and loss reduction measures for low-voltage distribution networks.Firstly,analyze the composition of line loss.Secondly,based on the obtained analysis results,a neural network model for calculating line losses in low-voltage distribution networks is constructed.After clarifying the specific causes of line losses in low-voltage distribution networks,measures such as reactive power control,reasonable selection and determination of energy consumption levels and layout positions of distribution transformers,and optimization of measurement and statistical control are proposed to reduce losses.Applying the loss reduction measures proposed in this article to practical applications can effectively control the loss rate of low-voltage distribution networks.At the same time,this study can also provide important reference for the development of related work.
