摘要
随着电力行业发展水平的不断提升,新能源不断被接入且在各个地区得到有效应用。基于此,文章就智能配电网分布式光伏电源并网保护技术进行研究,首先从实际案例出发,就分布式光伏电源在智能配电网中的应用价值进行分析,然后从故障分析和保护分析两个角度探讨分布式光伏电源对电流保护的影响,最后就运行方式、距离保护、继电保护和分布式发电单元保护的技术方案给予说明。
With the development of the electric power industry, new energy sources have been connected and applied effectivelyin various regions. Based on this, this paper studies the protection technology of distributed photovoltaic power in smart distributionnetwork. Firstly, the application value of distributed photovoltaic power in smart distribution network is analyzed from the actual case.Then, the influence of distributed photovoltaic generation on current protection is discussed from two aspects of fault analysis andprotection analysis. Finally, the technical scheme of operation mode, distance protection, relay protection and distributed generationunit protection are explained.
