摘　　要：无功支撑能力是光伏逆变器的重要性能,光伏逆变器需具备根据指令调节无功的能力,并在电压跌落时提供相应无功电流,以满足光伏逆变器并网要求,保障规模化光伏发电并网运行的安全稳定性。德国BDEW标准规定了接入中压电网的发电厂无功支撑能力等并网性能技术要求,标准内容覆盖光伏发电系统。针对该标准,研究了光伏逆变器静态及动态无功支撑能力检测及评价技术,并完成无功支撑能力实验室型式试验检测。Reactive power support ability is one of the important performance of photovohaic inverters.Photovoltaic inverter should have the ability to adjust reactive power according to dispatch instructions,and provide reactive current when voltage drops, in order to ensure the safety and stability of grid which large-scale photovohaic systems connected to.The German standard BDEW provides access to the medium voltage power grid interconnection pr- operties, such as power reactive power support ability of the technical requirements, which covers photovohaic power generation systems.This paper researches on the static and dynamic reactive power support capacity detection and evaluation technology of photovoltaic inverter based on the standard.A photovohaic inverter is taken as an example, to complete the reactive power support ability type testing laboratory testing.
