摘要
直流输电系统是实现高电压、大容量、远距离送电和区域电网互联的一个重要技术手段,对于大规模新能源发电的跨区域消纳具有重要的作用。以大规模光伏发电发电接入西北某电网为对象,建立光伏电站模型,分析光伏电站不同运行方式及电网扰动情况下对直流系统的影响,并提出为保证大规模光伏发电接入后直流系统稳定运行的措施与建议。
The DC transmission system is an important technical means for high voltage, large capacity and long distance power transmission and intereonnection of regional power grids, and it plays a very important play for trans-regional digestion for large-scaled new energy generation. Based on integration of the large-scaled PV （photovohaic） power generation with a certain power grid in Northwest China, this paper establishes a PV power station model and explores the impacts of the PV station on the DC system under different operation modes and grid disturbances. Finally it puts forward suggestions and measures to guarantee the stable operation of the DC system with the large scale PV power generation integrated with the system.
