摘　　要：针对配电网谐波治理前后的负荷水平不完全一致所导致的谐波治理真实节能效果无法量化的问题,以将谐波治理前后的负荷状态化归至同一水平为目标,提出了配电网谐波治理降损效果实证方法。首先对主要电力设备谐波损耗倍数进行原理分析;进而得到谐波损耗的数学模型,并给出了配电网谐波损耗与基波损耗的关系;最后将谐波治理前后的网络基波损耗值化归为同一基准,提出了谐波损耗折算值求解的方法,得到了谐波治理后的真实节能量,并通过算例验证了本方法的实用性和有效性。Real energy-saving effect cannot be quantified because of the different load levels before and after the distribution network harmonic control. This paper aims at making the load state before and after the harmonic control to be on the same level,and raises empirical method of the loss reduction effect which is caused by distribution network harmonic control. Firstly,the principle of major electrical equipment harmonic losses multiples is analyzed. Then,the mathematical model of harmonic losses and the relationship between the harmonic loss and fundamental loss is obtained. Finally,the fundamental loss before and after harmonic control is made to the same load level,and the method of the discounted value of the harmonic losses is raised,and the real energy savings after the harmonic control is obtained. The practicality and effectiveness of the empirical method is verified by an example.
