摘　　要：为保证配电网的运行管理效果,本文以多接入点分布式光伏发电系统运行状态为依据,研究多接入点分布式光伏发电系统介入后对配电网谐波和配电网电压的交互影响机理,分析其谐波分布和电压波动情况。测试结果显示,通过分析多接入点分布式光伏发电系统介入后对配电网运行状态的影响,能够有效掌握光伏发电系统接入配电网后各线路的电压波动结果,并计算最大电压波动结果,掌握配电网在光伏接入后的功率标幺值结果,有效保证发电系统的应用效果,满足相应应用需求。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.
