摘要

光伏电站无功补偿装置的型式一般为SVG+FC或全SVG。针对北方大型光伏电站

依据站址光强辐射强度分布曲线

通过全寿命周期的经济及技术方面的对比

对无功补偿装置形式SVG+FC和全SVG两种型式进行比较。通过比较分析可知:对于所建北方100 MW光伏电站模型

由于夜间无辐照度所占时间比例较大

无功补偿宜采用SVG+FC

其中FC容量选择为整个光伏电站无功补偿固定容量。从技术角度讲

由于SVG故障率略高

采用SVG+FC对光伏电站来说更为可靠。研究结果可供光伏电站设计相关同行及有关研究部门参考。

Abstract

The type of reactive power compensation device of PV power station is in general divided into SVG+FC or total SVG. As for the large PV power station in the north part of China and in accordance with distribution curve of radiation intensity at the stationsite

such two type of reactive power compensation device as SVG+FC and whole SVG are compared by the comparison in both economic and technical aspects of the whole life period.It is known by the comparison and analysis that for the 100 MW PV power station model established in the north region

the choice of SVG+FC is preferable for the reactive power compensation due to large percentage rate of by no radiation intensity at night

in which the choice of FC capacity is the fixed capacity of reactive compensation of the whole PV power station. From point view of the technology

since the fault rate of SVG is a bit higher

the choice of SVG+FC is more reliable for the PV power station.The study result can be sued as reference for the related industry and research institute rated to the design to the PV powerstation.
