摘　　要：受电网结构及地理环境等因素限制的中西部地区电网,通常具有电源接入点少、供电能力薄弱及可再生能源丰富等特点。以新疆某地区弱电网为例,光伏发电系统大规模接入电网,在实际并网中会产生大量谐波电流,对电网运行造成严重影响。为此,对接入新能源光伏电站的谐波特性开展测试与分析,利用谐波特性分析测试装置,基于相关谐波特性的标准定量,评估了新能源接入后的电网侧谐波特性水平。The power grid in the central and western regions is limited by factors such as power grid structure and geographical environment,and usually has the characteristics of few power access points,weak power supply capacity and abundant renewable energy.Taking the weak current network in a certain region of Xinjiang as an example,photovoltaic power generation system will generate a large number of harmonic currents in the actual grid connection,which will have a serious impact on the operation of the grid.To this end,the harmonic characteristics of the new energy photovoltaic power station are tested and analyzed.Using the harmonic characteristic analysis test device,based on the standard quantification of the relevant harmonic characteristics,the level of harmonic characteristics on the grid side after the new energy connection is evaluated.
