光伏发电系统并网电能质量测试数据分析

Analysis on power quality of grid-connected photovoltaic generation system

太阳能是可再生能源,光伏发电是太阳能发电的主流,近些年来,世界范围内太阳能光伏技术和光伏产业发展很快,江西省的光伏电站也在逐渐增加。厚田沙漠光伏电站是江西省内第一个并网发电的光伏发电系统,结合厚田沙漠光伏电站的并网电能质量测试,详细介绍了开展光伏电站并网电能质量测试的步骤,同时依照测试数据对光伏发电的功率变化、电压偏差、闪变以及谐波含量等方面进行了分析,可为今后光伏电站并网测试提供参考,同时为深入研究光伏并网对电网电能质量的影响提供可靠依据。

Photovoltaic generation is the mainstream of solar power generation for solar power is renewable energy.Recently,with the development of photovoltaic technology,photovoltaic generation stations in Jiangxi has increased.Houtian photovoltaic generation station is the first grid-connected photovoltaic generation system.With the power quality test in the station,power quality test procedure is presented and the test result is analyzed based on power change,voltage deviation,flicker and harmonic.The analysis provide reference for grid-connected test in photovoltaic generation station.
