| 摘 要： | 随着大规模光伏电站在蒙西电网并网，势必将对电网产生一系列影响：光照强度和阴影分布影响电站出力，对系统调峰提出更高的要求；逆变器及无功补偿装置选择不当影响系统正常运行。本文研究了光伏电站出力变化范围及统计趋势，并提出逆变器及无功补偿装置的控制模式，即逆变器需具备恒电压控制、恒功率因数控制和恒无功功率控制，无功补偿装置需使用恒电压控制模式，同时分析了光伏电站对蒙西电网无功电压、电能质量等方面的影响，并提出相应的改进措施。

| Abstract: | According to the practical situation of Inner Mongolia Grid, analyzed factors affecting the output of power station and requirements of peak-load regulation of the system after large scale PV power station grid getting connected, also researched and studied about inverter and choice of reactive power compensation device, then proposed controlling mode of inverter and reactive power compensation device. Besides, analyzed affections of PV power station to reactive voltage in Inner Mongolia Grid, quality of electric energy, and etc., then put forward improving measures. |
