To ensure the operation and management effectiveness of the distribution network,this paper takes the operation status of the multiple access point distributed photovoltaic power generation system as the basis,studies the interactive impact mechanism of the multiple access point distributed photovoltaic power generation system intervention on the harmonics and voltage of the distribution network,and analyzes its harmonic distribution and voltage fluctuations.The test results show that by analyzing the impact of the intervention of multiple access point distributed photovoltaic power generation system on the operation status of the distribution network,it is possible to effectively grasp the voltage fluctuation results of each line after the photovoltaic power generation system is connected to the distribution network,calculate the maximum voltage fluctuation results,and grasp the power standard value results of the distribution network after photovoltaic connection,effectively ensuring the application effect of the power generation system and meeting the corresponding application needs.
