摘要 光伏发电与常规发电技术相比,发电形式极为简洁,发电过程不消耗资源,环境友好,光伏发电技术已逐渐被全世界接受,并成为最被看重的新能源发电技术。新疆省由于其特殊的地理优势,光能资源尤其丰富,同时再加上国家经济政策的倾斜,仅2013年底就有100多家光伏电站集中并网发电,然而光伏电站的大规模接入,势必对电网产生一定的影响。本文针对新疆某电网的实际情况,采用中国电力科学研究院“PSD电力系统软件工具”对光伏接入进行了详细的计算及仿真,并基于上述研究着重分析光伏接入对线路以及变压器保护的影响。本项目的开展对光伏接入选择合理的继电保护配置及方式,保证电网的安全、稳定、可靠运行具有积极意义。

Abstract:Compare with the conventional power generation technology, photovoltaic (PV) power generation is resource-saving, environment-friendly, and has become the great importance as new energy power generation technology around the world. Because of the unique geographical advantage, sufficient sunshine and national policy support, only at the end of 2013 there were more than 100 PV power generations had generated in XinJiang. But with the large-scale photovoltaic (PV) power generation, it must have influence to the power network. In view of the actual situation of XinJiang power grid, this paper mainly discusses the effect to the line and transformer protection base on the modeling and simulation of large-scale PV integration by the “PSD Power Tools” of China Electric Power Research Institute. This discusses is beneficial for the selection of relay protection, and has positive significance to ensure the safety, stable and reliable operation of the power grid.
