The electronic electronic level of the modern power m88 com live casino registersystem is increasing，Power Electronic Device while improving the flexibility and controllability of the system，It also injected a large number of harmonics into the system。distributed new energy and electric vehicles、Harmony sources such as residents' load and other harmonic sources are decentralized and connected to the grid，Make the harmonic more obvious volatility and time -degeneration，The background of the grid is increasingly serious。For the effective harmonic governance，Need to evaluate the responsibility of each harmonic source。This paper proposes for the radiation distribution networkd-pmulayered partitional harmonic responsibility assessment method，The m88 sports bettingcore idea is based on the topology of the distribution networkd-pmucloth point, starting with harmonic exceeding standards, withd-pmuis boundary，Divide the molecular area layer by layer by the end of the branch，Gradually refine the harmonic liability through the operation between levels。Based on a wide range of linear plural domains, the smallest two -multiplication method (WL-CPLS) Return to the harmonic responsibility evaluation model，Improving the calculation efficiency; based ond-pmuHigh sampling frequency data proposes multiple harmonic liability division indicators of multiple time standards，revealed the dynamic changes in the comprehensive harmonic responsibility of each m88 com live casino registerchild area。Considering that there are more nodes in the network，d-pmuThe key node generally installed on the distribution network。In order to ensure that there is a source of unknown harmonic sources, the main harmonic source can still be located and divided the harmonic liability，This paper studies different quantitiesd-pmuConfiguration on the impact of the evaluation of harmonic liability; the proposed method is suitable for anyd-pmuquantity and configuration radiation -like distribution system.
