摘要
光伏发电作为清洁无污染的可再生能源,其发展正受到人们越来越多的关注。光伏电站因其出力的随机性,对电网电能质量产生一定影响。文章以哈密地区某60 MWp光伏电站为例,提出两种不同接入系统方案。利用PSASP软件进行仿真分析,分别讨论两种不同接入方案并网后,光伏电站在电网最大和最小运行方式下对电网的潮流分布和短路电流的影响,结合经济性比较提出合理的接入方案,并提出改善电能质量的建议。
Photovoltaic power generation as a clean and pollution-free renewable energy,its development attracts more and more attentions of people. Due to the randomness of photovoltaic plant,it would have an effect on the quality of power supply when it is connected to grid. This paper comes up with two different plans about the 60 MWp photovoltaic power plants connected to region grid in some area of Hami. By using PSASP simulation software,it analyzes two different access schemes under the condition of minimum and maximum mode of operation,and discusses the load flow and short circuit current influence when it is connected to grid,combining with the economical comparison,a reasonable access scheme is put forward,as well as the suggestion to improve the power quality.
