摘要
针对分布式电源应用趋势越来越明显但在接入系统方面却缺乏相应技术分析与论证的问题,重点研究了各类分布式电源接入后对电网运行的影响结果。首先,从运行模式和接口方式对分布式电源进行分析,以便于分类研究不同的影响结果;其次,分析分布式电源接入电网的方式,构建配电网典型模型,以作为分布式电源接入影响性分析的基础;最后通过接入后模型的理论计算,研究分布式电源接入电网对稳态特性和电能质量、保护等方面带来的影响,从而为配电网规划技术原则的修改提供理论基础。
Aiming at the problem that distributed generation,an increasingly popular role in grid,accessing to grid is lack of corresponding technical analysis and evidence,this paper mainly studies impact of distributed generation in different types on grid..Distributed generation are classified from two categories of operating mode and interface mode in this paper firstly according to classification research.Then,its connection manner to power grid is analyzed with building a typical model of distributed network for basis.Finally,combined with the theoretical analysis and the case study,the impacts of the grid-connected distributed generation on power grid such as stable characteristics,power quality and the protection,issues are analyzed,which provides theoretical support for the modification of power grid guidelines.
