10 kV长线路系统通用降损方法与节能技术分析

Analysis of General Loss Reduction Method and Energy Saving Technology for 10 kV Long Line System

线路损耗是衡量电网运行效率的关键性指标,主要评估电能全寿命转换和输送过程中产生的损耗。损耗越大,说明电能利用效率越低。10 kV配电系统中产生的损耗量占整个电力系统损耗的约80%,对电力系统经济性效益有着较大的影响。文章主要针对10 kV配电线路的线损问题开展研究,深入挖掘产生线损的机理以及影响线损的关键参数,针对性地提出10 kV长线路的线损治理方法,并在最后选择一段典型线路进行重点改造,验证其方法的经济性。文章在目前新能源发电并网较多的情况下,引入了大量的影响线损的因素。选择本文设计的方法和措施可有效降低配电线路损耗的指标,进一步提升配电网运行效率。

Line loss is a key index to measure the operation efficiency of power grid.It mainly evaluates the loss generated in the process of power life-cycle conversion and transmission.The greater the loss,the lower the power utilization efficiency.The loss generated in 10 kV distribution system accounts for about 80%of the loss of the whole power system,which has a serious impact on the economic benefits of the power system,Therefore,this paper mainly studies the line loss of 10 kV distribution line,deeply excavates the mechanism of line loss and the key parameters affecting line loss,puts forward the line loss treatment method of 10 kV long line,and finally selects a typical line for key method modification to verify the economic improvement of the method.The method studied in this paper introduces a large number of factors affecting line loss when there are many new energy power generation connected to the grid.The methods and measures designed in this paper can effectively reduce the indicators of distribution line loss and further improve the operation efficiency of distribution network.
