摘要: |
为了研究并网风电场和光伏电站内应用全容量SVG(Static Var Generator)动态无功补偿的必要性和特别要求,重点从调节特性与响应速度等性能指标对比研究了SVC(Static Var Compensator)和SVG两种型式的动态无功补偿装置。针对甘肃已并网多个新能源项目,分析了大型风电场升压站在无功配置方案和无功补偿设备运行方面存在的误区和一些细节问题,并结合典型事故进一步分析了电网故障情况下SVG对系统无功和电压的支撑作用。同时,研究了集中并网光伏电站内SVG的选型和典型电气接线方案以及SVG在实际工程应用中的常见故障问题,对类似工程具有指导意义。 |

Abstract: |
In order to study the necessity and specification requirements of static var generator (SVG) dynamic reactive power compensation applied in large-scale grid connected wind power plant and photovoltaic substation, this paper comparatively studies the two kinds of reactive power compensation, i.e. static var compensator and static var generator, in terms of regulation characteristics, response speed and other performance indicators. For grid connected new energy projects in Gansu Province, it analyzes some details and misunderstandings about reactive power configuration and reactive power device operating experience of wind power plant. And it researches voltage support and reactive power of SVG to power system under grid failure condition, combined with analysis of typical accident case. Meanwhile, SVG selection, typical wiring program and common failure problems of centralized grid-connected photovoltaic substation in practical engineering applications are studied, which is benefit to similar projects. |
